Model Hysteresis voltage [V]
1P 200 V 10
3P 400 V 15
When the brake chopper is controlled by the hysteresis voltage, the switching
pattern is shown as below:
Fig. 8-47: Switching pattern_hysteresis voltage
When the duty cycle is set as 100 %, the switching will be only according to the
hysteresis. It means that there is no switching after 10ms (100 Hz).
E4.02 Stall overvoltage prevention level
Setting range 200 V class: 300 ~ 390 V; 400 V class: 600 ~ 885 V
Minimum unit 1 V
Factory default 200 V class: 390 V; 400 V class: 885 V
With stall overvoltage protection, the frequency converter detects the DC bus
voltage during deceleration and compares it with "Stall overvoltage prevention
level" [E4.02].
● When the DC bus voltage exceeds the stall over voltage protection level, the
output frequency stops decreasing.
● When the DC bus voltage is lower than the stall overvoltage protection level,
the frequency converter resumes deceleration.
