Figure 4.3.99 Slip compensation output frequency
Slip compensation gain at high speed (18-01)
(1) It is not required to adjust the Slip compensation gain at high speed if the motor is loaded.
(2) After adjusting parameter 18-00 it is recommended to increase the reference frequency and
check the motor speed. In case of a speed error increase the value of 18-01 to adjust the
compensation.
(3) Increase the motor rated frequency (01-12 base frequency) and increase the value of 18-01 to
reduce the speed error.
(4) Compared to 18-00, 18-01 serves as a variable gain for the full speed range.
(5) If the speed accuracy becomes worse due to an increase in motor temperature it is
recommended to use a combination of 18-00 and 18-01 for adjustment.
Parameter 18-01 determines the slip compensation at the motor rated speed and is calculated follows:
