Functional extensions are options which increase the flexibility of an AC drive by extending I/Os and by providing dedicated interfaces for a wide variety of feedback devices.
General Purpose I/O OC7C0
This I/O option extends the standard inputs and outputs integrated in the drive.
Main specification
- 3 digital inputs, supporting PNP logic
- 2 digital outputs, configurable PNP, NPN, push-pull, pulse range 0-100 kHz
- 2 analog inputs: 0/4-20 mA, 0 to 10 V DC, -10 to +10 V DC
- Temperature sensors: Up to 3 PT100’s can be connected in series to the input. PT1000, Ni1000 (A/B), KTY81, KTY82, KTY84
- 1 analog output: 0/4-20 mA

I/O and Relay Option OC7C1
This I/O option offers an extended number of control inputs and outputs.
- 6 digital inputs, single-ended
- 2 digital outputs, configurable PNP, NPN, push-pull
- 1 isolated thermistor input
- 2 analog inputs: -20/0 to +20 mA or -10/0 to +10 V
- 1 analog output: 0-20 mA or 0-10 V
- 3 relay outputs
- 2 x NO, NC
- 1 x NO
- 250 V AC 3 A max. (50/60 Hz)
- 24 V DC 2 A resistive load

Relay Option OC7R0
This relay option makes it possible to extend relay functions with 3 additional relay outputs.
Main specification
- 2 x relay output NO/NC
- 1 x relay output NO
- Maximal terminal load (AC-1): Resistive load: 250 V AC, 2 A
- Maximum terminal load (AC-15): Inductive load: 250 V AC, 0.2 A
- Maximum terminal load (DC-1): Resistive load: 80 V DC, 2 A

Encoder/Resolver Option OC7M0
The Encoder/Resolver option supports connection of various devices as speed/position feedback or reference.
The following device types are supported:
- Incremental encoders with 2 or 3 channels (TTL, HTL, SinCos without zero pulse)
- TTL encoder simulation output
- Absolute encoders (SSI, EnDat, BiSS, Hiperface, Hiperface DSL)
- Resolvers
Depending on the device type, you can connect 1 or 2 devices. Up to 2 feedback systems can be connected. Learn more from our operating guide.

Temperature Measurement OC7T0
Use the temperature measurement option to measure and monitor application temperatures or to protect the motor from being overheated by monitoring the temperature of motor bearings (2 pcs) and motor windings (3 pcs).
Main specifications
- Sensor inputs: 5 channels
- Sensor connection: 2-wire, 3-wire, or 4-wire
