1-4 Product Overview
1560D-UM051D-EN-P – February 2005
Starting Modes (cont.) Current Limit Start Y
This starting mode provides a fixed, reduced-voltage start that is used when
limiting the maximum starting current is necessary. The Current Limit level
is user-adjustable from 50% to 600% of the motor's full-load ampere rating,
and the current limit time is user-adjustable from 0 to 30 seconds. Once the
MV Dialog Plus™ controller senses that the motor has reached the up-to-
speed condition during the current limit starting mode, the output voltage
automatically switches to full voltage and the bypass contactor is closed.
