6.23 Permanent magnetic motors

H : Step-out detection current level

H : Step-out detection time6

H : High-speed torque adjustment coefficient

•Function

If the permanent magnet motor (PM motor) steps out and if the exciting current increases (it increases in such a case) and remains above the value set with H for the period of time set with H, the inverter will judge the motor to be stepping out and trip it. At that time, the trip message "UQWV" is displayed.

Title	Function	Adjustment range	Default setting
H	Step-out detection current level	10 ~ 150 (%) / (A)	100
H	Step-out detection time	0.0: No detection	0.0
		0.1 ~ 25.0 [s]
H	High-speed torque adjustment coefficient	0.00 ~ 650.0	0.00

Note 1: When using an PM motor, consult your Toshiba dealer, since the inverter is not compatible with all types of PM motors.

Note 2: The inverter may fail to detect step-out in some cases, because it uses an electrical method to detect step-out. To avoid detection failures, you are recommended to install a mechanical step-out detector.

Note 3: There is no need adjust H under normal conditions. (Do not change the setting, unless otherwise instructed by Toshiba technical staff.)
