Tip
INVT braking resistor Applicable for inverters
INVT braking resistor: Suitable for INVT frequency inverters. The INVT frequency inverters have built-in brake choppers to which these resistors can be connected in order to dissipate energy from the braking of the motor.Use braking resistors if the load has a high moment of inertia and the frequency inverter goes into the fault state during braking (deceleration).

INVT GD28 frequency inverter with STO and optional communication card
From
€82.08 *
If you need a compact frequency inverter with built-in STO, brake chopper and EMC filter that can be integrated into PROFINET, EtherCAT, EtherNet/IP or Modbus TCP when required, the INVT GD28 is a universal inverter from 0.2 to 2.2 kW for single-phase 230 V and 0.4 to 22 kW for three-phase 400 V. Modbus RTU comes as standard; a single card covers all Ethernet fieldbuses: the EC-TX149.
🏭 Typical Applications
Packaging, printing and machine tools: STO to SIL 3 / PL e is built into every model. According to INVT, sensorless vector control delivers up to 200 % starting torque at 0.5 Hz, with a torque response below 10 ms.
Pumps, fans and compressors: integrated PID controller, energy-saving control at partial load and speed tracking for a smooth restart of a coasting motor. In light-duty mode, one unit covers the next larger motor rating.
Conveyors, mixers and filling machines: linear or S-curve ramps, up to 16 preset speeds and ride-through during short mains dips.
Plants with different fieldbuses: The EC-TX149 handles PROFINET, EtherCAT, EtherNet/IP and Modbus TCP — the protocol is selected by parameter. One card type in stock instead of four.
⚙️ Control and Functions
Two control modes: V/f control and sensorless vector control (SVC) with a speed range of 1:100 and ±0.2 % speed accuracy.
Asynchronous and permanent-magnet synchronous motors, autotuning of motor parameters.
Dual rating: heavy duty 150 % for 60 s and 180 % for 10 s, light duty 110 % for 60 s and 150 % for 10 s.
Output frequency 0–599 Hz, frequency resolution 0.01 Hz.
Frequency setpoint via keypad, potentiometer, analog input, pulse input, preset speeds, PID or Modbus — setpoint channels can be combined.
Motor temperature monitoring: PTC directly on DI4, PT100, PT1000 or KTY84 via the AO→AI analog combination.
Fewer nuisance trips: overvoltage and overcurrent stall control, automatic voltage regulation (AVR).
🔌 Connections and Control I/O
5 digital inputs: 4 standard inputs and 1 high-speed input up to 50 kHz, NPN and PNP (factory setting PNP).
2 analog inputs: AI1 0–10 V or 0–20 mA, AI2 −10–+10 V or 0–20 mA.
1 analog output 0–10 V or 0–20 mA and 1 high-speed digital output up to 50 kHz.
1 relay output: changeover contact, 250 V AC / 3 A or 30 V DC / 1 A.
RS-485 with Modbus RTU as terminal, RJ45 for the external keypad.
USB-C: parameter setting, parameter copy and monitoring with the INVT Workshop software — the PC powers the control electronics, no mains voltage and no interface converter needed.
Spring-clamp terminals for the control wiring, one slot for expansion cards.
⚠️ Before Ordering
Select by output current, not by kW: The motor rated current must match the inverter's output current. The kW figure in the model name applies to heavy duty and a standard four-pole motor.
EMC filter: With the built-in filter, the single-phase models meet category C2, the three-phase models C3. C2 on three-phase units requires an external filter.
External brake resistor: The brake chopper is built in; the resistor is connected to (+)/PB. Do not go below the minimum resistance for each power rating.
Using STO: The STO inputs are jumpered at the factory. If STO is part of your safety concept, remove the jumpers and wire a safety relay or safety PLC.
Keypads: A simple LED keypad is built in. For the cabinet door, the BOP-270 (LED) and SOP-28 (LCD) keypads are available. While a USB-C cable is plugged in, the external keypad is disabled.

INVT frequency inverter vector control GD-27, STO function, applicable for AM and PM, IP20
€341.70 *
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.
