2.11 Auxiliary parameters
2.11.1 Slip compensation (Pr. 95 , Pr. 96 , Pr. 97 )
<Setting>
*When this value is made smaller, response will be faster.
However, as load inertia is greater, a regenerative overvoltage (OVT) error is
more liable to occur.
The inverter output current may be used to assume motor slip to keep the motor
speed constant.

95
0.01 to 50% Used to set the rated motor slip.
0, - - - Slip compensation is not made.
96 0.01 to 10s Used to set the slip compensation response time. (*)
97
0
Slip compensation is not made in the constant output range
(frequency range above the frequency set in Pr. 3).
- - - Slip compensation is made in the constant output range.
REMARKS
When making slip compensation at 60Hz, set the maximum frequency (Pr. 1) to slightly higher
than 60Hz.
In the factory setting status, it is clamped at 60Hz.
