If you are looking for a compact frequency inverter for driving asynchronous motors and need real Modbus RTU, vector control and an integrated brake chopper, the Kinco KC100 offers a cost-effective solution without compromises on functionality or reliability. With power ratings from 0.4 to 5.5 kW, the KC100 covers most standard applications in mechanical engineering and automation — single-phase 230 V or three-phase 400 V. 🏭 Typical Applications Pumps & fans with PID control: The integrated PID controller enables simple pressure regulation, flow control or temperature management — without external controllers. Frequency setpoint via analog input 0–10 V or 0–20 mA. Conveyor technology and series machines: The S-curve ramp provides smooth acceleration and deceleration — ideal for positioning tasks or high-inertia loads such as conveyor belts and winding drives. Integration into Modbus RTU networks: Unlike its predecessor CV20, the KC100 uses real Modbus RTU (RS-485) with standard function codes — it integrates seamlessly into existing PLC architectures and can be parameterized via a higher-level controller. Systems with unstable mains voltage: The AVR voltage regulation actively compensates for mains fluctuations — useful in industrial networks with poor power quality or unstable supply. ⚙️ Improvements Over the CV20 Predecessor Kinco developed the KC100 (introduced 2024) as a targeted upgrade to the CV20 series, passing on cost reductions in power electronics directly to customers: AVR voltage regulation for active compensation of mains voltage fluctuations Vector control (SVC) — 150% rated torque from 0.5 Hz, speed control range 1:200 S-curve ramp for smooth acceleration and deceleration, four ramp groups selectable Integrated brake chopper for braking high-inertia loads (external braking resistor connectable) Autotuning of motor parameters for improved running smoothness Speed tracking — detects current motor speed and enables flying start from the actual speed Power dip ride-through (Instantaneous Non-Stop) — during a mains dip, the drive feeds back kinetic motor energy to maintain operation briefly without tripping Wave-by-wave current limiting — limits current pulse-by-pulse during sudden load spikes, preventing nuisance trips without requiring intervention from the higher-level controller Real Modbus RTU (RS-485) with standard function codes — the CV20 used proprietary function code 41 for permanent parameterization Maximum frequency 600 Hz for high-speed applications Demand-controlled fan speed instead of continuous operation — extends fan service life Spring-clamp terminals on the I/O terminal for fast wiring in series production Extension port (CN2) for external operator panel — cable up to 10 m, parameter copy between drives supported The following functions are also available (as with the CV20): Frequency setpoint via frequency table with 8 fixed values using 3 digital inputs Frequency setpoint via analog input 0–10 V and 0–20 mA Frequency setpoint via Modbus RTU and integrated PID controller Frequency setpoint via pulse input up to 50 kHz ⚠️ Known Limitations No integrated EMC filter: An external EMC filter is required for CE-compliant operation in European installations. Suitable filters for each model are available separately. 🔌 Connections & I/O 4 digital inputs (DI1–DI4): NPN/PNP compatible, active level 9–30 V. DI1–DI3 are standard inputs; DI4 can also be used as a high-speed pulse input up to 50 kHz. 1 analog input (AI): 0–10 V or 0–20 mA, switchable via DIP switch.

The GD27 from INVT is a flexible and compact frequency inverter that is ideal for use in series machines.STO function (SIL 2) for safe shutdown and requirements in accordance with the Machinery Directive Built-in EMC filter (C2 for 230 V, C3 for 400 V) Suitable for three-phase asynchronous and synchronous motors Integrated brake chopper for inertial generative loads GD27 models with 230 V and 0.4 kW or 0.7 kW are passively cooled and have no fan The spring terminals for the I/O on the front are very suitable for quick wiring in series machines Note: The digital input terminals are NPN (negative switching). They must therefore be controlled with a relay output or NPN output. Alternatively, the control commands can also be transmitted via Modbus RTU (2-wire). This saves wiring work and increases the variety of functions that can be addressed via the control unit. If you require digital inputs in PNP version (positive switching), the INVT GD20 is well suited.

🏭 Variable Frequency Drive with IP66 Protection for Harsh Environments Anyone looking for a VFD that works in dusty, wet or water-spray environments – in agriculture, food processing, outdoor installations or demanding industrial settings – will find the M-Driver M980 a robust and cost-effective solution. The M980 brings IP66 protection directly to the drive housing: no additional enclosure required, mount directly at the machine. 🏭 Typical Applications Pumps and fans in wet or outdoor areas: Irrigation systems, wastewater pumps, cold-room ventilation – IP66 protection allows direct installation without a separate enclosure. The built-in PID controller handles constant-pressure regulation on its own. Food and agricultural environments: Conveyor drives in food processing, stable ventilation, silo conveying – wherever washdown water and dust are part of daily life and conventional IP20 drives only survive inside a cabinet. Construction sites and mobile equipment: Mixers, concrete conveyor systems or portable pump units that are occasionally exposed to water spray and have no fixed control cabinet location. Simple retrofit projects: Replace direct-on-line starters, reduce energy consumption, limit inrush current – without a complex terminal layout. The 8-segment multi-speed function works with just 2 digital inputs. 🖥️ Key Technical Data Control mode: Open-loop vector control (SVC) and V/F curve (linear, square, multi-point). Sufficient for most pump, fan and basic conveyor applications. Output frequency: 0 – 500 Hz, carrier frequency 0.5 – 16 kHz (automatically adjusted by load) Overload capability (G-type): 150% rated current for 60 s, 180% for 3 s Starting torque (SVC): 150% at 0.5 Hz – for hard-to-start loads Supply voltage: Single-phase 200–240 V AC or three-phase 380–480 V AC (±10%, 50/60 Hz) depending on variant Power range: 0.75 kW to 15 kW (three-phase) or 0.75 kW to 4 kW (single-phase) 🔌 I/O and Connections Digital inputs: 2 × (DI3, DI4), opto-isolated, bipolar (active-high or active-low selectable) – configurable as run/stop, direction, fault reset, multi-speed, preset frequencies and more Analog input: 1 × AI1 – selectable 0–10 V / 4–20 mA / 0–20 mA, with adjustable gain and offset Relay outputs: 2 × relay (T1, T2) – T1 and T2 each one normally open contact; T2 additionally with normally closed contact; 250 V AC / 3 A, 30 V DC / 1 A Analog output: 1 × AO1 – selectable 0–10 V / 4–20 mA / 0–20 mA; configurable for output frequency, current, voltage, power or Modbus control Auxiliary supply: 10 V and 24 V output terminals for external wiring (e.g. potentiometer 1–5 kΩ) 🌐 Communication and Built-in Functions Modbus RTU via RS-485 (terminals S+/S-): Full remote control and parameter access via Modbus. Address 1–249 freely configurable, baud rate 9,600 – 115,200 bps, multiple data formats (8-N-1, 8-E-1, 8-O-1, 8-N-2). Built-in PID controller: Direct connection of a pressure sensor (0–10 V, 4–20 mA or variants) to AI1. Setpoint via keypad, potentiometer or Modbus. Sleep/wake function, anti-freeze operation and water shortage detection included. 8-segment multi-speed with internal PLC sequencing (timing, individual acceleration/deceleration per segment configurable). Further features: Speed-tracking restart, S-curve ramp, skip frequency (resonance protection), DC braking, over-voltage/over-current stall prevention. ⚠️ Important Limitations – Please Check Before Purchasing Only 2 digital inputs (DI3 and DI4): Applications with a complex terminal concept – safety relay chains, multiple external speed-step switches, enable signals from a safety PLC – quickly reach the limits of what is possible. Where start/stop, setpoint and control commands can be handled entirely via Modbus RTU (RS-485), many applications can get by without additional DI terminals – which significantly reduces this limitation. However, anyone who needs hardware DI signals from sensors or safety relays and requires more than 2 will need a different drive. Digital inputs NPN only (sinking) – no PNP: Control inputs DI3 and DI4 are implemented as NPN inputs only (active-low, sinking). In Europe, most PLC output cards use PNP outputs (sourcing, 24 V switched to GND). Direct wiring from a PNP PLC to the M980 DI terminals is therefore not possible – an interposing relay, opto-isolator interface or a NPN-compatible PLC output is required. When using full Modbus RTU control, this issue does not apply. No brake chopper, no braking resistor connection: The M980 has neither a built-in brake chopper nor terminals for connecting an external braking resistor. With high-inertia loads (e.g. centrifuges, large-diameter fans, conveyors with frequent braking cycles), regenerative energy cannot be actively dissipated – the drive protects itself by tripping on overvoltage. Anyone requiring short deceleration times or dynamic braking must use a drive with an integrated brake chopper. Thermal derating above 40 °C: Rated output current applies up to 40 °C ambient. Above this, it decreases by 1.5% per degree; maximum permissible is 50 °C. For permanently higher temperatures, select the next higher power rating or provide active cooling. Altitude derating above 1,000 m: At high altitudes, cooling efficiency decreases due to thinner air. Derating: 1% per 100 m above 1,000 m; maximum operating altitude is 4,000 m. IP66 – but not for direct sunlight or corrosive atmospheres: Despite its IP66 rating, the manufacturer specifies installation away from direct sunlight, corrosive or flammable gases, oil mist and salt. For aggressive outdoor air (marine environments, chlorine-containing atmospheres), additional protective measures must be considered. No built-in EMC filter: spstiger exclusively stocks the variant without an integrated line filter. For operation on sensitive networks or in CE-compliant installations, an external EMC filter must be included in the design. 🏷️ Manufacturer and Reliability M-Driver is a brand specializing in robust variable frequency drives with a focus on high-protection variants for demanding operating conditions. The M980 is CE-certified and meets the EMC requirements for industrial use in Europe. spstiger distributes and supports the M980 for the German and European market – please contact us with any commissioning or parametrization questions. 🔧 Mounting and Scope of Delivery Mounting: Screw fixing, vertical, on mounting plate or wall (no DIN rail clip). Minimum clearances: sides ≥ 10 mm, top and bottom ≥ 200 mm (for 0.75–22 kW). Mount multiple drives side by side rather than stacked – heat dissipates upward, stacking causes thermal interference. Scope of delivery: M980 frequency inverter. The separately available copy keypad (item no. md.copykeypad) enables convenient parameter backup and transfer between drives.
