Switching off power supply via
firmware
The "parking axis" firmware command (C1600) causes the encoder power
supply to be switched off.
7.1.13 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 X156 or X104).
7.1.14 Operation with standard motors
KMS02 near motor servo drives without X104 connection (encoder
interface = "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 KMS
data sheet).
Selecting standard motors
The table below shows the nominal powers P
nenn
of standard motors which
can be operated. The data are subject to the following conditions:
● Motor design:
4-pole standard motor (2 pole pairs) with rated voltage 3 AC 400 V,
50 Hz at mains voltage U
LN
≥ 3 AC 400 V or
● Operation at minimum switching frequency f

● Rotary field at output with f

performance profile
Observe the performance data P

and P

in the
"UEL_P_e" performance profile of the supply unit and the
performance data of the KCU drive connection box.
