1: Enable
If only activate the slip compensation function in V/F control mode, this parameters used for selecting slip
compensation function.
LED Hundreds digit: Reserve
LED Thousands digit:
Over modulation
0: Over modulation allowed
1: Over modulation not allowed
E-24
Voltage auto regulation function
Range:0,1,2,3
Default:2
0: Disable
1: Enable in full process
2: Disable only in deceleration
Output voltage auto regulation function that is AVR function. When AVR function disable, the output voltage change
vary with input voltage. When the AVR enable, the output voltage will keep in setting value as long as the minimum
of fluctuation input voltage bigger than output voltage setting (Motor rated voltage). When the power supply voltage
less than rated output voltage, the output voltage will decrease follow with input voltage.

The jog frequency function has the highest control priority (terminal jog function). It means in any condition, when
jog command is valid, the inverter immediately run from the current running frequency to the jog frequency based
on jog accelerates/decelerates time. The jog accelerates/decelerates time is defined as same as
accelerates/decelerates time, which can be configured by the keyboard, control terminal or job function control
command of RS485.
Note: The setting value of the jog running frequency is only limited by the upper limit frequency. Only the
priority of job terminal control free from limitation of running control command channel. Other jog
command have priority only under the same running control command channel, such as the keypad job
command is enabled only in the operator keypad control running.
E-28 Start
frequency
Range:0.00-60.00Hz Default:0.50Hz
E-29
Start frequency holding time Range time:0.0-20.0s
Default:0.0s
Start frequency:
The initial output frequency when inverter starting. The large starting torque is available if the
starting frequency is properly set. It can gain high impact when starting instantaneous for some load that has a
bigger static friction force in static status. But it will result in a trip if the value is set to big.
Start frequency holding time:
It means the inverter keeps running time under starting frequency.
