parameter) until the effective positive velocity limit value, i.e.
minimum value (S-0-0091, S-0-0038), has been reached.

P-0-1216, Motor potentiometer, deceleration
Input min/max: Default value: Unit:
MPB: 100000 S-0-0160
In conjunction with the motor potentiometer available in the "velocity
control" mode, this parameter is used for the following purposes:
• For linear velocity change:
definition of the velocity change by which the ramp velocity changes
when setting P-0-1214, bit9 ("ramp-")
∆P-0-1218 = activation time * [P-0-1216]
• For square velocity change:
definition of the acceleration change by which the ramp velocity
changes within 2s when setting P-0-1214, bit9 ("ramp-")
∆deceleration = activation time * ([P-0-1216] / 2s)
Note: With the input activated the velocity is reduced in linear or
square form (see P-0-1214, Motor potentiometer, control
parameter) until the effective negative velocity limit value, i.e.
minimum value (S-0-0091, S-0-0039), has been reached.

P-0-1217, Motor potentiometer, step size
Input min/max: Default value: Unit:
MPB: 500000 S-0-0044
This parameter takes effect when bit 4 "change by constant velocity step"
is one in P-0-1214, Motor potentiometer, control parameter.
P-0-1218, Motor potentiometer, command value, i.e. the velocity
command value, is increased by the velocity value with every positive
edge at the ramp input ramp+ until the positive velocity limit value
S-0-0038 has been reached. With every negative edge at the ramp input
ramp- it is reduced by the velocity value until the negative velocity limit
value S-0-0039 has been reached.
