The speed of motor rotor decreases as load increases. In order to ensure that the speed of
rotor is close to synchronous speed, motor could start slip frequency when motor is on rated
load. When the speed of motor is far lower than the objective value, increase the setting
value of F3-30.

F3-31=1
Upload the parameters from the control panel of inverter to the EEPROM on
keypad. Upon the completion of uploading, F3-31=0 set automatically.
F3-31=2
Download the parameters from the EEPROM on keypad to the control panel of
inverter. Upon the completion of downloading, F3-31=0 set automatically.
The function may be applied to the setting parameter copy between different
inverters, and to save the initial parameters defined by user. When the parameters
are edited by mistake, the inverter cannot work normally, please download the
parameter to reset

Bit setting value=0
Monitoring frequency shows absolute value when motor
forwards/reverses.
Bit setting value=1
Monitoring frequency shows positive/negative value when motor
forwards/ reverses.
F4-15 is bit operation, only setting corresponding bit of monitoring frequency = 0 or 1. For
instance: when motor forwards/reverses, the monitoring output frequency and estimated
slip frequency shows positive/negative value respectively, but monitoring the other
frequency shows absolute value, only set the 0
th
bit=1 (corresponding to the output
frequency) and the 5
th
bit=1 (corresponding to the estimated slip), and set other bits = 0, i.e.
F4-15=XX10X001.
