7.27 Connecting the motors in parallel
Parameter p0306 is assigned in a STARTER commissioning screen. When the subsequent
parameters are set, p0306 is included in the calculation of the current limit (p0640) and in the
reference current (p2002). Parameter p0306 has a value range of 1 to 50, and is it
dependent on the motor data set (MDS).
1. To connect motors in parallel, select the corresponding motor in the selection screen and
activate the "Parallel motor connection" option.
2. Enter the number of motors in the parallel connection in the entry field "Number".
This display and input function is available for vector control only. For servo control, the
parallel connection of motors can only be configured using the expert list (parameter
p0306).
Motors with integrated DRIVE-CLiQ interface (SINAMICS Sensor Module Integrated) can
also be connected in parallel. The first motor is connected to DRIVE-CLiQ via the encoder.
The additional motors must be identical. Using parameter p0306 and the encoder
information obtained via DRIVE-CLiQ, it is possible to determine all the necessary motor
data.
