KFU 2-/4-
39
5.3 Optional
Components
Thanks to the modular hardware components, the frequency inverters can be inte-
grated in the automation concept easily. The standard and optional modules are rec-
ognized during the initialization, and the controller functionality is adjusted automati-
cally. For the information required for installation and handling of the optional mod-
ules, refer to the corresponding documentation.
Danger!
The hardware modules at slots B and C may only be assembled and
disassembled after the frequency inverter has been disconnected safely
from power supply. Wait for some minutes until the DC link capacitors
have discharged before starting the work.
The unit may only be connected with the power supply switched off.
Make sure that the frequency inverter is discharged.

B
C
Slot for customer-specific adaptation of the control inputs
and outputs to various applications:
EM-ENC: extended speed sensor evaluation
EM-RES: resolver evaluation
EM-IO: analog and digital inputs and outputs
EM-SYS: system bus
