Activity
Depending on the drive transformer version (dry or oil filled), integrate
the transformer protection and monitoring devices in the alarm and
shutdown train of the drive. A range of digital inputs are available for
this purpose on the customer terminal strip.
Options L80 to L82
The PTC thermistor sensors (type A PTC resistors) must be connec‐
ted to the thermistor motor protection unit ‑F at terminals T1 and T2 for
alarm/shutdown purposes.
Options L91; L93, 94, 95, 96
The resistance thermometers must be connected to evaluation unit
‑A1 to evaluate the PT100. The two-wire or three-wire system can be
used here to connect the PT100 sensors. The sensors are divided into
two groups. This must be taken into account when the evaluation is
performed (factory setting).
To check the correct wiring and macro interconnection, first select
limits below the ambient temperature and check the messages.
After checking the correct wiring and macro interconnection, set the
limit values for alarm and shutdown to match the component moni‐
tored.
Option K50
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
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 transformers at the medium-voltage level, which
supply 3-phase 100 V AC as the synchronization voltage. Connect the
voltage transformers on the drive side to terminals.
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
