Number of motors connected in parallel / Motor qty

Description: Number of motors that can be operated in parallel using one motor data set.
Depending on the motor number entered, internally an equivalent motor is calculated.
The following should be carefully observed for motors connected in series:
The following rating plate data should only be entered for one motor:
- resistances and inductances: p0350 ... p0361
- currents: p0305, p0320, p0323, p0325, p0329, p0389, p0390, p0391, p0392
- power ratings: p0307
- masses/moments of inertia: p0341, p0344
All other parameters take into account the replacement/equivalent motor (e.g. r0331, r0333).
Recommend.: For motors connected in parallel, external thermal protection should be provided for each individual motor.
Dependency: Refer to: r0331
Caution: The motors to be connected in parallel must be of the same type and size (same order no. (MLFB)).
The mounting regulations when connecting motors in parallel must be carefully maintained! Especially for
synchronous motors, the pole position of motors that are rigidly coupled with one another (mechanically) must be
identical.
The number of motors set must correspond to the number of motors that are actually connected in parallel.
After changing p0306, it is imperative that the control parameters are adapted (e.g. using automatic calculation with
p0340 = 1).
For synchronous motors connected in parallel with p1300 >= 20, be following applies:
- the individual motors must be mechanically coupled with one another and the EMF must be aligned to one another.
For induction motors that are connected in parallel, but which are not mechanically coupled with one another, then
the following applies:
- an individual motor must not be loaded beyond its stall point.
Notice: If p0306 is changed during quick commissioning (p0010 = 1), then the maximum current p0640 is appropriately pre-
assigned. This is not the case when commissioning the motor (p0010 = 3).
Note: Only operation with U/f characteristic makes sense if more than 10 identical motors are connected in parallel.
Separately-excited synchronous motors must not be connected in parallel.
Synchronous and reluctance motors that are not coupled with one another align themselves when the pulses are
switched in. If the motors have different load levels, then equalization currents flow between the motors.

-100000.00 [kW]
Description: Sets the rated motor power (rating plate).
Dependency: IECdrives (p0100 = 0): Units kW
NEMA drives (p0100 = 1): Units hp
Refer to: p0100
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note: For generators, a negative rated power should be entered.
