Range: 0 to 150% of slip speed
• Press to edit the value.
• Press ▲/ ▼ to make changes to the value.
• Press to accept the new value OR
• Press ESC to abandon the value change.
Motor slip is the difference between the shaft speed and the frequency applied to the motor
(synchronous speed) and is dependent on load. Slip Comp can provide compensation for this varying
slip to produce constant shaft speed under varying loads. The MSC-3 estimates the slip of the motor
using the parameters entered in the MOTOR parameters menu and the motor load. A value of 100%
will make the shaft speed equal the synchronous speed. Flux Plus may be used in conjunction with Slip
Comp to provide increase output torque at low speeds.

• Press once to begin the selection.
• Use the ▲ / ▼ buttons to select the audible frequency.
• Press to conrm the choice.
This value sets the maximum frequency that the drive uses in the creation of its PWM output voltage.
This frequency is noticeable as an audible sound that the motor makes. Usually higher settings produce
less audible noise but increase the switching losses which produce more heat in the drive. For most
efcient operation select 2 kHz.
