Option K50
Sensor Module
for detecting the
actual motor
speed
If a function for detecting the actual speed value is provided to improve
speed accuracy, connect the motor rotary pulse encoder to the SMC30
( A... ).
Option L32
Voltage Sens‐
ing Module
If, for process-related reasons, the drive needs to be restarted after
power failures of > 100 ms, connect the synchronization voltage of the
line upstream of the medium-voltage circuit-breaker to the VSM 10. To
do so, install voltage converters at the medium-voltage level, which
supply 3-phase 100 VAC as the synchronization voltage. Connect the
voltage converters on the drive side to terminals.
Switch-on conditions with water-cooled drives
Before switching on the drive for the first time, you must reduce the conductivity of the de-
ionized water circuit to < 1 µS. After filling the re-cooling unit, switch it on for several hours
before switching on the drive. The conductivity reduction may also be necessary if the
drive has been out of service for an extended period (such as maintenance/revision times).
Required tools
To install the connections, you will require:
● Spanner or socket spanner (w/f 10)
● Spanner or socket spanner (w/f 13)
● Spanner or socket spanner (w/f 16/17)
● Spanner or socket spanner (w/f 18/19)
● Hexagon-socket spanner (size 8)
● Torque spanner, max. 50 Nm
● Screwdriver, size 2
● Screwdriver, Torx T20
● Screwdriver, Torx T30
