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(100%)
Settings XXXA(30~120%)
This parameter will limit the AC drive output current in order to prevent the motor from
overheating.
The value entered must be in Amps, and should be found on the motor nameplate.
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(40%)
Settings XXXA(5~90%)
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)
a
Factory setting 0.0
Settings 0.0~25.0%
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.
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)
a
Factory setting 0.0
Settings
0.0-10.0%
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.
