S2-05 695h
High Frequency Slip
Compensation Gain
HF SlipComp Gain
Sets the gain for the Motor Slip Compensation at
Hi-Speed Function. Although this parameter rarely
needs to be changed, adjustments might be needed
under the following circumstances:
If the motor at constant speed is slower than the
frequency reference, increase S2-05.
If the motor at constant speed is faster than the
frequency reference, decrease S2-05.

High Frequency Slip
Compensation Primary Delay Time
HF SlipComp Time
Sets the filter on the output side of the Slip
Compensation at Hi-Speed Function. Although this
parameter rarely needs to be changed, adjustments
might be needed under the following
circumstances:
-Decrease the setting when the slip compensation
response is too slow.
-Increase this setting when speed is unstable.

High Frequency Slip
Compensation Limit
HF SlipComp Lim Sets the upper limit for the Slip Compensation at
Hi-Speed Function as a percentage of the motor
rated slip (E2-02).

High Frequency Slip
Compensation Selection During
Regeneration
HF SlipCompRegen
When Slip Compensation during Regeneration at
Hi-Speed is activated and a regenerative load is
applied, it might be necessary to use a dynamic
braking option (braking resistor, braking resistor
unit, or braking unit).

Motor 2 Control Mode Switchover
Frequency
HF SwOver Freq 2
Sets the frequency of switching from Closed Loop
Vector Control to V/f Control for Motor 2
This function is disabled when 0 or 400Hz is set,
the inverter runs as V/f Control when 0 is set, and
Closed Loop Vector Control when 400Hz is set.
However, OPE21 occurs when the relations among
Control Mode Switch Frequency (S2-11) and PG
Pulse per Revolution (F1-31) and Numbers of
Motor Poles (E4-04) are set higher than the
permissible input frequency of PG option.

Sets the hysteresis width of Control Mode Switch
for Motor 2.

Motor 2 High Frequency Slip
Compensation Gain
HF SlipCompGain2
Sets the gain for the Motor Slip Compensation at
Hi-Speed Function for Motor 2. Although this
parameter rarely needs to be changed, adjustments
might be needed under the following
circumstances:
-If the motor at constant speed is slower than the
frequency reference, increase S2-15.
-If the motor at constant speed is faster than the
frequency reference, decrease S2-15.
