This parameter is used to set whether the drive will report main circuit undervoltage alarm when 
undervoltage occurs to the main power supply. 
Setting value    Protection   
0  Do not display the undervoltage fault of the main circuit (Er13-1) 
[1]  Display the undervoltage fault of the main circuit (Er13-1) and stop

Undervoltage detection time 
of main power supply 
Setting range  Default Unit  Available mode
70~2000  70  ms  P S T F
This parameter is used to set the undervoltage detection time of the main power supply. 
Note: The function is invalid if it is set to 2000.

P4.39  Speed deviation setting
Setting range  Default Unit Available mode 
0~20000  0  r/min P  S F
This parameter is used to set the detection condition of the speed error. If the absolute value of 
the minus of actual speed command and motor speed is larger than this value and lasts for more 
than 100ms, it will report speed error alarm. 
Note: If it is set to 0, the speed error will not be detected.

Setting range  Default Unit  Available mode
0~20000  20000 r/min  P S T F
This parameter is used to set the max. speed limit for forward speed command. 
Note: The default value and setting range of the parameter is relative to the drive power level.
