H30: Motor Type Select
Range:
0.2-7.5kW (Default: 7.5kW - This value is set automatically according to
the drive model.)
Description:
This parameter sets the motor capacity. H32 [Rated Motor Slip], H33 [Rated
Motor Current], H34 [No Load Motor Current], H42 [Stator Resistance],
and H44 [Leakage Inductance] are automatically changed according to
motor capacity.
If H34 [Motor No-load Current] is not correct, run the drive without the
load in V/F mode and check the current. Enter this value into H34 [No load
current].
H31: Number of Motor Poles
Range: 2-12 (Default: 4)
Description: This is used to display the motor speed. If you set this value to 2, the drive
will display 3600 rpm instead of 1800rpm at 60Hz output frequency. (See
motor nameplate).
H32: Rated Slip Frequency
Range:
0-10Hz (2.33Hz)
Description:
This is used in ‘Slip Compensation’ control. If you set this value incorrectly,
the motor may stall during slip compensation control (See motor
nameplate).
Motor rated slip freq [Hz] = (Rated input freq. [Hz] – (Motor rpm * P/120)
P = Number of motor poles
(Ex) In the case of 60Hz, 4 pole, 1730 rpm motor
Motor rated slip freq [Hz]= (60[Hz]-(1750[rpm] * 4/120))
= 60[Hz]-58.67[Hz]=1.33[Hz]
H33: Motor Rated Current
Range:
0.5 - 50A (Default: 26.3A)
Description:
This is a very important parameter that must be set correctly. This value is
referenced in many functions of the drive. Enter motor rated current on the
nameplate.
