p0306[0...n]
Number of motors connected in parallel / Motor qty
Access level: 1
Can be changed: C2(1, 3)
Unit group: -
Min:
1
Description:
Sets the number (count) 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 observed in motors connected in parallel:
Rating plate data should only be entered for one motor: p0305, p0307
The following parameters are also only valid for one motor: p0320, p0341, p0344, p0350 ... p0361
All other motor parameters take into account the replacement/equivalent motor (e.g. r0331, r0333).
Recommendation:
For motors connected in parallel, external thermal protection should be provided for each individual motor.
Dependency:
See also: 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!
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, p3900 > 0).
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.
Note
Only operation with U/f characteristic makes sense if more than 10 identical motors are connected in parallel.
p0307[0...n]
Rated motor power / Mot P_rated
Access level: 1
Can be changed: C2(1, 3)
Unit group: 14_6
Min:
0.00 [kW]
Description:
Sets the rated motor power (rating plate).
Dependency:
IECdrives (p0100 = 0): Units kW
NEMA drives (p0100 = 1): Units hp
NEMA drives (p0100 = 2): Unit kW
See also: 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
Once the Control Unit has booted for the first time or if the factory settings have been restored, the parameter is pre-
assigned to match the power unit.
