Parameters for the ramp generator
Note: Dynamic acceleration and deceleration results in high startup
and braking currents. This also applies to the emergency stop
by way of the stop ramp. In deceleration the motor drops into
regenerative operation and increases the DC-link voltage
(DCV).

Explanatory notes
• If one of the two ramps (acceleration ramp ACCRx, deceleration
ramp DECRx) of a characteristic data set is set to 0 (zero), both
ramps are inactive.
• The DC braking function has priority over the stop ramp STPRx.
• Standard control signals with the assignment of the ramps are set
out in Table 5.29 (section 5.2.7).
• The ramp values can only be changed online as from firmware V.
