YASKAWA CIMR-G5A Series - Multi-Function Input Settings: H1-01 through H1-06

6.1 Common Settings
6-13
Lengthen the minimum baseblock time (L2-03) when an overcurrent (OC) occurs during stopping. When the
power to an induction motor is turned OFF, the counter-electromotive force generated by the residual magnet-
ic field in the motor can cause an overcurrent to be detected when DC injection braking is applied.

has
elapsed. The time T

depends upon the output frequency when the stop command is
input and the deceleration time.
