Switching off power supply via
firmware
The "parking axis" firmware command (C1600) causes the encoder power
supply to be switched off.

Length of motor cables and encoder cables at KMS
The allowed length of motor cables at connection X156 or X104 of KMS is
limited (see description of connection point
7.1.12
Operation with standard motors
KMS02 near motor servo drives without X104 connection (encoder inter‐
face = "NNN") are provided for operating converter-proof standard motors..
Guide value "Rise of voltage at output"
When selecting standard motors, make sure that they comply with
the occurring voltage load "rise of voltage at output" (see
Selecting standard motors
The table below shows the nominal powers P
