Short Description Deceleration rate

Description

The DEC command defines the deceleration ramp for the velocity control loop. The DEC deceleration/braking ramp is only used for setpoint step changes that result in a velocity decrease (braking). The ACC parameter is used for acceleration.

The DEC braking ramp applies to all setpoint changes, whether they are provided in analog or digital form. Separate braking ramps (DECSTOP/DECDIS) are used for setpoint changes that are generated internally in emergency stop situations (e.g. amplifier fault, or removal of the amplifier enable).
