5-41
6. Set Pr.00-10 = 2~5 after any errors are eliminated. If needed, now adjust other parameters
based on the requirement of the application.
05-01
Full-Load Current of Motor 1 Factory setting A xx.x
Settings ****A(30~120%)
1
This parameter will limit the AC drive output current in order to prevent the motor from
overheating.
1
The value entered must be in Amps, and should be found on the motor nameplate.
1
This parameter and Pr. 05-01 must be programmed correctly if the drive is to operated in
the Vector or Torque control mode, the Electronic Thermal Overload Relay is used (Pr.
06-09), or if the Slip Compensation function is used (Pr. 05-04).
05-02
No-Load Current of Motor 1 Factory setting A xx.x
Settings XXXA(5~90%)
1
The motor’s no-load current must be less than Pr. 05-01. This parameter directly
effects the amount of the slip compensation generated and the no-load current during
Vector control mode. Please set this parameter carefully.
05-03
Torque Compensation of Motor 1 (for the V/F Mode Only) Factory setting 0.0
Settings 0.0~25.0%
1
This parameter increases the amount of voltage the drive will output to the motor during
operation to increase motor torque. The V/F Torque Compensation is based on the
setting of the parameter.
1
Be careful when setting this parameter. Always start at the lowest setting and increase the
value until sufficient torque is achieved. A large Torque Compensation may generate
more voltage than needed and the motor will overheat and possibly be damaged.
05-04
Slip Compensation of Motor 1 (for V/F mode only) Factory setting 0.0
Settings 0.0-10.0%
1
While driving an asynchronous motor, an increasing load will cause an increase in slip.
This parameter may be used to compensate the nominal slip within a range of 0.0-10.0%.
When the output current of the drive is greater than the motor’s no-load current (setting of
Pr. 05-02), the drive will adjust the output frequency to the motor to compensate for slip.
Note 1. If Pr.05-02 > the rated current of the motor, the slip compensation will not work
correctly.
Note 2. To obtain effective slip compensation, use the auto tune feature Pr.05-00.
