Additional Settings Required For Units That Are Connected In Parallel - Siemens SINAMICS G150 Operating Instructions Manual

5.3.3

Additional settings required for units that are connected in parallel

After commissioning with STARTER, for the (parallel) units listed below, in addition, the
following settings must be made:
● For 3 AC 380 to 480 V:
● For 3 AC 500 to 600 V:
● For 3 AC 660 to 690 V:
Settings to monitor the checkback signal from the main contactor or circuit breaker for 12-pulse infeed
The checkback contacts of the main contactors and the circuit breakers are connected in
series in the factory and wired to digital input 5 of the Control Unit.
After the drive unit has been commissioned, the checkback signal monitoring function must
be activated. This is realized using parameter p0860{VECTOR} = 722.5{CU}.
If the monitoring function for the main contactor or circuit breaker checkback signal is not
activated, then the drive could be powered up even if the main contactor or circuit breaker
on an individual system fails. This could overload and damage the input rectifiers on the
individual system.
NOTICE
When resetting (restoring) the parameterization to the factory setting, this setting must be
again made after the drive unit has been recommissioned.
Settings for motor connection to a motor with one-winding system
During commissioning, a motor with several winding systems is automatically defined.
The setting for a one-winding system is made after commissioning has been completed by
setting parameter p7003 to 0.
NOTICE
If the "motor with a one-winding system" is not set using p7003 = 0, then the drive can be
powered down (tripped) during the motor identification routine with an "overcurrent" fault
message. The system will not be properly tuned.
NOTICE
When resetting (restoring) the parameterization to the factory setting, this setting must be
again made after the drive unit has been recommissioned.
