5.2.2 Automatic Restart After Momentary Power Loss (P051)
When momentary power loss occurs, operation restarts automatically.
Setting
Description
0
Not provided (factory default)
1*
Continuous operation after power recovery within 2 seconds
2 **
Continuous operation after power recovery within control logic time (no fault output)
* Holds the operation signal to continue operation after recovery from momentary power loss.
** When “2” is selected, operation restarts if power supply voltage returns to its normal level (level before
power loss). No fault signal is output.
5.2.3 Carrier Frequency (P050)
This function sets the inverter output transistor switching frequency (carrier frequency). This is used to reduce motor noise and leakage current.
