VFD-L-I Series
4-40 Revision July 2009, SW V1.1
Group 7: Motor Parameters
07-00 Motor Rated Current Unit: 1
Settings 30 to 120% Factory Setting: 85
This parameter needs to be set according to the motor nameplate. The factory setting is set
by the rated current of the AC motor drive. It is used to limit the AC drive output current in
order to prevent the motor from overheating.
07-01
Motor No-load Current
Unit: 1
Settings 0 to 90% Factory Setting: 50
The rated current of the AC drive is regarded as 100%. Motor setting of no-load current will
effect the slip compensation. The setting value must be less than motor rated current set in
Pr.07-00
07-02 Torque Compensation Unit: 1
Settings 0 to 10 Factory Setting: 1
This parameter may be set so that the AC drive will increase its voltage output during start-up
to obtain a higher initial starting torque.
07-03 Slip Compensation Unit: 0.1
Settings 0 to 10 Factory Setting: 0.0
While driving an asynchronous motor, load on the AC drive will increase, causing an increase
in slip. This parameter may be used to compensate the nominal slip within a range of 0.0 to
10.0. When the output current of the AC drive is greater than the motor no-load current
(Pr.07-01), the AC drive will adjust its output frequency according to this parameter.
07-04
PID Control Mode Selection
Factory Setting: 2
Settings 0 No function
1 PID modulation of Master frequency
2 PID modu master frequency shift
