iC7 Functional extensions

  • Overview
  • Documents

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.

This I/O option extends the standard inputs and outputs integrated in the drive.

Main specification:

  • 3 digital and inputs, supporting PNP and NPN 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: 1xPT100, 2x PT100, 3xPT100, PT1000, Ni1000 (A/B), KTY81, KTY82, KTY84
  • 1 analog output: 0/4-20 mA

This pluggable relay option makes it possible to extend relay functions with 3 additional relay outputs.

Main specification:

  • 2 x NO, NC
  • 1 x NO
  • 250 V AC 2 A max. (50/60 Hz)
  • 24 V DC 2 A resistive load

The optional Encoder/Resolver interface 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)
  • Absolute encoders (SSI, EnDat, BiSS, Hiperface, Hiperface DSL)
  • Resolvers

Depending on the device type, you can connect 1 or 2 devices.
