1.8 Setting the Motor and Frequency Measurement Source for Computing the Sync Speed and Slip
IM WT3001E-51EN
• Equation for Deriving the Slip
The unit of synchronous speed is fixed to min
slip, set the scaling coefficient of the rotating speed (see section 1.7) so that the unit
of rotating speed s also min
Synchronous speed (min
Slip (%) =

Please select a stable voltage or current (supplied by the motor) with small distortion or noise
for the frequency measurement source.
