Santerno Sinus M - 10.6 Slip compensation

10-11
 H33: Enter the motor nameplate rated current.
 H34: Enter the measured current when the motor is running at rated frequency without load. Enter 50%
of the rated motor current when it is difficult to measure the motor no load current.
 H36: Enter motor efficiency as shown on the nameplate.
 H37: Select load inertia related to the motor inertia as shown below.
H37
[Load inertia
rate]
0
Less than 10 times motor
inertia
1 About 10 times motor inertia
2
Greater than 10 times motor
inertia
 As the loads are heavier, the speed gap between rated RPM and synchronous speed is greater (see
the figure below). This function compensates the speed gap due to the slip.
