H 7 [Dwell frequency] - 0.1 - 400 5.00 Hz
H 8 [Dwell time] - 0 - 10 0.0 sec
In this setting, motor begins to accelerate after dwell operation is executed for dwell

time at the dwell frequency.
It is mainly used to release mechanical brake in elevators after operating at dwell

frequency.
►
Dwell frequency: This function is used to output torque in an intended direction. It is
useful in hoisting applications to get enough torque before releasing a mechanical
brake. Rated Slip frequency is calculated by the formula shown below.

Set H40
– [Control mode select] to 1 {Slip compensation}. 
This function enables the motor to run in constant speed by compensating inherent slip

in an induction motor.
