Output side
The following symmetrical layout must be adhered to on the output side:
● Symmetrical connection setup
between Motor Modules Booksize and asynchronous motor
● Identical motor cables
– Same output type and same cross-section
– Same motor cable lengths
– Adherence to the required minimum cable lengths; see Chapter: Decoupling Motor
Modules (Page 30)
Control mode
Only vector control with and without encoder feedback may be used as the control mode.
Limiting circulating currents
To limit possible circulating currents between the Motor Modules Booksize connected in
parallel, a minimum inductance per converter output is required.
Additional information is provided in Chapter: Decoupling Motor Modules (Page 30).
Current reduction
For a parallel connection, the current reduction in relation to the rated currents for the individual
Motor Modules is 5%.
Asynchronous motors
Asynchronous motors with a common winding system (one-winding system) can be used. All
of the parallel windings within the motor must be connected in such a way that from the outside
they look like a single winding system.
Note
No group drive
Connecting several asynchronous motors of the same type to one Motor Module is not
permitted when using the parallel connection of Motor Modules Booksize.
Note
Motor protection
The motor is protected by the thermal model of the firmware. Alternatively, the motor
temperature can also be monitored using corresponding motor sensors.
