68 Chapter 6 Parameter Descriptions
Set appropriate switching frequency F092.
First tune P (F088) and I (F089) for high-speed application, ensuring no
oscillation and short response time.
Next, tune P (F090) and I (F091) for low-speed application, ensure no
oscillation and good response performance at low frequency.
F093 Slip compensation gain
Range: 0, 50.0%~250.0%
【
100.0%
】
F093 is used in calculating slip frequency. The setting 100% means rated slip
frequency corresponds to rated torque current. The user may
decrease/increase the settings of F093 to adjust the speed control's
difference accurately.
F094 Motoring torque limit
Range: 0.0%~200.0%
【
100.0%
】
F095 Braking torque limit
Range: 0.0%~200.0%
【
100.0%
】
Torque limiting is used to limit the speed regulator's output torque current.
Torque limit is the percentage of the drive's rated current; If the torque limit is
100%, then the torque current limit is the drive's rated current. F094 and
F095 limit the output torque in motorizing state and braking state respectively,
as shown in Figure 6-16.

Note
When operating in regeneration state, adjust braking torque limit (F095) if necessary.
Given large braking torque, it is required to connect braking unit on DC bus bar,
otherwise bus bar overvoltage fault may occur.
