Startup
9.8.5
Startup of multi-motor drive
Multi-motor drives are mechanically connected to each other (e.g. chain drive with
several motors). Observe the notes in the publication "Multi-Motor Drives".
Multi-motor drives are possible with installed identical SEW motors only.
•
Set the multi parameter of the motor startup to the number of connected motors.
9.8.6
Startup of group drives
Group drives are mechanically decoupled from each other (e.g. different conveyor
belts). In this operating mode, the inverter operates without slip compensation and with
a constant V/f ratio.
You can operate a group of asynchronous motors on one inverter in V/f characteristic
curve operating mode. Important:
•
Select V/f operating mode
•
Set the power of the largest motor
•
Disable automatic adjustment P320/330
•
Set boost P321/331 to zero
•
Set IxR compensation P322/332 to zero
•
Set slip compensation P324/334 to zero
•
Set current limitation P303/313 to 1.5 times the total current of all motors
•
Set I
rated
UL monitoring P345/346 to the total current of the connected motors.
Implement motor protection individually.
In this operating mode, the inverter operates without slip compensation and with a
constant V/f ratio.
