Emotron VS10 - Example 1: Automatic DC Braking When the Motor Is Started

280 01-6203-01R3, CG Drives & Automation
10.4.1. Example 1: Automatic DC braking when the motor is started
In order that the DC braking is automatically active when the motor is started, the start
method "DC braking [1]" must be set in 0x2838:001 (P203.01).
• The DC braking is carried out with the braking current set in 0x2B84:001 (P704.01).
• Only after the hold time 0x2B84:002 (P704.02) has elapsed, the motor is accelerated to
the setpoint.

① After the start command, the DC braking is active. Only after the hold time
0x2B84:002 (P704.02) has elapsed, the motor is accelerated to the setpoint.
② The motor is stopped with the stop method set in 0x2838:003 (P203.03). In the
example: Stop with standard ramp.
③ If the inverter is disabled, the motor coasts.
