Overvoltage stall protection
voltage (220V)
E1-01
Overvoltage stall protection
voltage (380V)
When E1-00 is set to 1, if DC bus voltage exceeds this parameter value, it will dynamically
adjust output frequency, prolong deceleration time. This value is a percentage value compared
to standard DC bus voltage.
E1-02

Undervoltage stall

0: Disabled
1: Enabled
Under momentary voltage drop or momentary power loss, the drive will accordingly drop
output frequency, and compensate the voltage drop via the energy feedback from load, so as
to maintain consecutive running, no trip. This function applies to fans and centrifugal pumps
and such.
E1-03

Overload alarm

Unit's place: detection option

0: Always detect
Overload alarm works all the time during drive running.
1: Detect at constant speed only
Overload pre-alarm only works during constant-speed running of inverter.
Decade: compared object

0: Rated current of motor
Compared object is the rated current relative to motor, and display "oL2" when the alarm is
given under this setting
1: Rated current of drive
Compared object is the rated current of drive, and display "oL1" when the alarm is given
under this setting.
Hundreds place: alarm option

0: Alarm and continue to run
When drive output current exceeds the level set by E1-04 and the lasting time attains
parameter value of E1-05, the drive will alarm but continue its running.
1: Protection enabled and coast to stop
When drive output current exceeds the level set by E1-04 and the lasting time attains
parameter value of E1-05, the drive will display overload fault and coast to stop.
