iC7 Functional extensions

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

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 

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  

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. 

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).​
