Various motor switchover variants can be enabled
The function motor switchover in the control means switchover between motor data set 1 (MD
1xxx) and 2 (2xxx).
Possible switchover variants are:
• Star/delta switchover, motor data set 1 star connection, motor data set 2 delta connection.
Switchover of the motor windings must be performed externally with contactors that are
controlled by the PLC. Synchronization with the drive is performed by the control and
status word of the cyclic interface.
• Switchover between two real motors. Motor data set 1 for motor 1, motor data set 2 for
motor 2. Motor switchover is performed externally using contactors, synchronization via
control and status words.
Note:
The machine for the 2nd motor must be parameterized in order to be able to enable the
star/delta switchover. The drive considers the 2nd motor to be parameterized if machine data
MD 2102 does not include the value 0.

1 = the drive is ready when those of
the following conditions apply
simultaneously:
– no ZK1 alarm
– terminal 63=1 (I/R module)
– terminal 64=1 (I/R module)
– terminal 663=1 (drive module)
0 = ZK2 parameterization errors are
not supported (default setting).
