DC Bus voltage control
option
➢
Unit’digit :Overvoltage stall control
0:overvoltage stall disabled
1:overvoltage stall enabled
2:overvoltage stall enabled self-adjustable
➢
The over-voltage stall function limits the amount of
power generated by the motor by extending the
deceleration time or even increasing the speed,
avoiding over-voltage on the DC side and reporting
over-voltage faults
Ten’unit:Undervoltage stall control
0:undervoltage stall disabled
1:Undervoltage stall(decelerate to zero
speed and be in standby mode,after
power restoring ,it will run again
automatically)
2: Undervoltage stall
deceleration(decelerate to zero and stop)
➢
The undervoltage stall function reduces the
motor power consumption or reduces the power
consumption of the motor or turns it into a
power generation operation to avoid the
undervoltage fault on the DC side.
➢
The undervoltage stall function is used when the
input power supply quality is poor (the power
supply voltage fluctuates downward or the sporadic
short power is suspended), and it is necessary to
keep the inverter running as much as possible.
