These parameters can be used only when specific optional parts are installed. Do not use these parameters
unless such parts are installed.
6.24 Permanent magnetic motors
H : Step-out detection current level (for PM motors)
H
: Step-out detection time (for PM motors)
• 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 (for PM
motors)
10 ~ 150(%) 100
H
Step-out detection time (for PM motors) 0.0 ~ 25.0 [sec] 1.0
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.
