Short Description

Deceleration Rate

Description

The DEC command defines the deceleration ramp for the velocity control loop (in msec) referred to the maximum velocity (the larger value of VLIM and VLIMN). 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.

For a setpoint step from VLIM/VLIMN to 0, the ramp generator generates a stepped ramp (with steps of 250 microseconds) that is completed within the set DEC time.

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).
