Group E4: Protection Parameters
E4.00
Software over voltage protection threshold Factory Default 810 V
Setting range 790 − 820 V Minimum unit 1 V
E4.01
Stall over voltage function Factory Default 0
Setting range 0、1 Minimum unit 1
E4.02
Stall over voltage protection level Factory Default 130.0 %
Setting range
120.0 % − 150.0 % (of rated
converter peak voltage)
Minimum unit 0.1 %
● Parameter ‘Stall over voltage function’ [E4.01] is used to activate or de‐
activate stall over voltage function.
–
0: Deactivated
– 1: Activated
● In stall over voltage protection, converter detects the bus voltage during
deceleration and compares it with ‘Stall over voltage protection level’
[E4.02].
● If bus voltage exceeds stall over voltage protection level, the converter
output frequency stops decrease.
● Only if bus voltage is lower than the stall over voltage protection level,
will the converter resume deceleration, as shown in fig. 7-52 "Stall over
voltage protection level" on page 133 :
Fig.7-52: Stall over voltage protection level
E4.03
Stall over current protection level Factory Default 150.0 %
Setting range
20.0 % − 200.0 % (of rated
converter output current)
Minimum unit 0.1 %
The function action will lead to longer acceleration time than set time.
During acceleration:
●
If the converter output current exceeds ‘Stall over current protection lev‐
el’, the converter output frequency will stop increase.
● Only if the converter output current is lower than ‘Stall over current pro‐
tection level’ [E4.03], will the converter resume acceleration, to avoid
stall over current.
