40. DC BRAKING MENU
40.1. Overview
When the IFD or VTC control algorithm are used, DC current can be injected into the motor to stop it. DC current may
be automatically injected at stop and/or at start; DC current injection may also be controlled by the terminal board. All
relevant parameters are included in the DC BRAKING MENU. The intensity of the DC current injected is expressed as a
percentage of the rated current of the active motor.
40.1.1. DC BRAKING AT START AND NON-CONDENSING
FUNCTION
To activate DC braking at start, set C216 to [YES]. Braking occurs after sending a START command, with a speed
reference other than zero, before the acceleration ramp. A START command may be one of the following: RUN
command or REV command sent via terminal board; START command from keypad, etc., depending on the preset
control mode. DC braking level and duration are set in the following parameters:
C220 Expressed as a percentage of the rated current of the controlled motor.
C218 Expressed in seconds.
