P50 Maximum acceleration, hoist
The set value corresponds to the maximum drive acceleration/deceleration. The value should
be 50 ... 100% higher than the set acceleration (P51). Input values less than 20 are interpreted
as ramp time.
Set manually according to manufacturer's or customer's specifications.

P51 Set acceleration, hoist
The set acceleration is an internal acceleration value. It is operative not only in the acceleration,
but also in the deceleration phase. Input values less than 20 are interpreted as ramp time. The
value should be approx. 75% of the maximum acceleration (P50).

P52 Factor for braking deceleration, hoist (MAN)
If zero is specified for the target velocity in manual (MAN) mode, the set deceleration resulting
from P51 * P52 is operative when braking.
Default: 1
min: 0.5
max: 5

Display: Always
P53 Acceleration reduction when hoisting
Percentage value of the set acceleration of the hoist (P51). The set acceleration is reduced to
this value (a_ref = P51 * P53/100) when hoisting.
Default: 100 [%]
min: 1 [%]
max: 100 [%]
Access code: 1
Display: Always
P54 Rounding, hoist
Initial and final rounding of the output velocity. The percentage value is based on the ramp-up
time to the maximum velocity. The rounding is active when the parameter is greater than zero.
This is only operative in MAN mode.
Default: 10 [%]
min: 0 [%]
max: 50 [%]
Access code: 2
Display: Always
P55 Smoothing of torque setpoint, hoist
In addition to the output velocity, the output acceleration is fed back to the PLC for the torque
precontrol of a velocity control loop.
