Motor Rated Current (Motor 0)

Settings
Use the following formula to calculate the percentage value entered in this parameter:
(Motor Current / AC Drive Current) x 100%
with Motor Current=Motor rated current in A on type shield
AC Drive Current=Rated current of AC drive in A (see Pr.00.01)
Pr.07.00 must be greater than Pr.07.01.
Example: Suppose that the rated current of 460V/2.0HP(1.5kW) is 4.2A with the factory setting
4.2A. The range that user can set is from 1.3A(4.2X30%) to 5.0A(4.2X120%). But when
Pr.07.00 is set to less than 1.7A(4.2X40%), it needs to set Pr.07.01 to be less than 30% FLA
first. In this way, Pr.07.00 is greater than Pr.07.01.
Pr.07.00 and Pr.07.01 must be set if the drive is programmed to operate in Vector Control
mode (Pr.00.10 = 1). They also must be set if the "Electronic Thermal Overload Relay"
(Pr.06.06) or "Slip Compensation"(Pr.07.03 and Pr.07.06) functions are selected.
The full-load current should be less than the rated current of the AC motor drive and should be
greater than 1/2 rated current of the AC motor drive.
Related parameters: Pr.00.01(Rated Current Display of the AC motor drive),
Pr.06.06(Electronic Thermal Overload Relay Selection), Pr.06.07(Electronic Thermal
Characteristic), Pr.07.01(Motor No-Load Current (Motor 0)), Pr.07.03(Slip Compensation
(Used without PG) (Motor 0)) and Pr.07.06(Motor Rated Slip (Motor 0))

Motor No-load Current (Motor 0)

07.01
Settings
This parameter is used to set the motor no-load current. The user must input motor no-load
current by the motor nameplate. The factory setting be set to 40% X the rated current of the
AC motor drive (refer to Pr.00.01 Rated Current Display of the AC motor drive).
Example: Suppose that the rated current of 460V/2.0hp(1.5kW) is 4.2A with factory setting
4.2A. The motor no-load current is 1.7A(4.2X40%) and it should set Pr.07.01 to 1.7.
This parameter must be set if the "Electronic Thermal Overload Relay" (Pr.06.06) or "Slip
Compensation"(Pr.07.03 and Pr.07.06) functions are selected.
