<F910: PM step-out detection current level>
<F911: PM step-out detection time>
■ Function
If the PM motor steps out and if the exciting current increases (it increases in such a case) and
remains over the value set by <F910: PM step-out detection current level > for the period of time set
by <F911: PM step-out detection time>, the inverter will judge the motor to be stepping out and trip
it.
At that time, the trip message "SOUT" is displayed.

Important
• When using an PM motor, consult your Toshiba distributor, since the inverter is not compatible
with all types of PM motors.
• 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.
Memo
• For setting of PM motor parameter, refer to [6. 23. 2].
