P 52 Motor Rated Current
Settings
30.0% FLA to 120.0% FLA
Factory setting is the AC drive rated current. When setting this parameter,
just input the motor rated current value without any calculation.
Use the following criteria to determine the setting of this parameter:
no-load current < rated current of motor < rated current of AC drive.
You can use this parameter to limit the output current to the motor as
to prevent overheat.
P 53 Motor No-Load Current
Settings
00%FLA to 99%FLA
The rated current of the AC drive means 100%. Setting of this parameter
affects the slip compensation. The setting value must be smaller than
the motor rated current setting in P52. (this parameter displays the
value of actual current.)
P 54 Torque Compensation
Settings
00 to 10
This parameter forces the AC drive to increase its voltage output during
start-up in order to obtain a higher initial starting torque.
Slip Compensation
P 55
Settings
0.00 to 10.00
This parameter can be used to compensate motor slip. Although no
linear, When the output current of the AC drive is greater than the
motor no-load current (P53), the AC drive will adjust its output frequency
according to this parameter.

P57 displays the rated current of the AC motor drive. By reading this
parameter the user can check if the AC motor drive is correct.

This function is used to limit the output power of the AC drive when
powering a "self-cooled motor" at low speed.
P 59 Electronic Thermal Motor Overload
Settings
30 to 300sec
The parameter determines the time required to activate the I t elect ronic
thermal motor overload protection. The graph below shows I t curves
at 150% output power for 1 minute.
