Acceleration/Deceleration
Units (acceleration)
ASCII: ACCUNIT
Select the unit for acceleration and ramp entries.
t_acc_total
This parameter determines the acceleration time to v_cmd.
t_dec_total
This parameter determines the deceleration (braking) time from v_cmd to zero.
Ramp
Determines which type of acceleration/braking ramp should be used to carry out a motion task.

Setting
The setting for the rate-of change limiting of the acceleration/braking ramps:
t_acc_total
t_dec_total

Offset in counts
Offset in SI units, unit is given by PUNIT
v_cmd as speed setpoint
speed setpoint from analog input 1
Default: 0
The drive is given a constant linear acceleration/deceleration to the target speed
To limit any jolting, the drive is accelerated/decelerated within the acceleration time along
an acceleration ramp without any discontinuities. The resulting speed characteristic corre-
sponds to a sine² curve.
The acceleration/braking ramps can be adjusted (in preparation).
