EXPLANATION OF PARAMETERS (6/7).
• Address
016
:
Gliss
, Motor Slip.
At this address is programmed the motor slip.
Example of the slip calculation :
For a 4 pole motor, 50 Hz, which without slip would turn at 1500 rpm, yet the motor
plaque states 1380 rpm,
the slip will be
1500 1380
1500
0,08 ie 8%

⇒ Program 08,0 %
If the RPM is not shown, use the table below once you have calculated the Id / In ratio
(starting current / nominal current)
