To set the ramp times, set the setpoint potentiometer to 0% first. After the
drive has come to a standstill, quickly turn it to 100%. Set the rise ramp with
the setting potentiometer t
up
to the desired time.

To set the descending ramp, quickly turn the command value potentiometer to
0% and set the desired time with the setpoint potentiometer t
down
.
The ramp setting process may have to be repeated several times.
With ramp operation, the initial reaction may be too strong. In this case,
it can be reduced by turning the setting potentiometer I
min
to the left.
Afterwards, the maximum modulation has to be readjusted again by setting the
setpoint potentiometer to 100% and setting the desired maximum modulation
by turning the setting potentiometer I
max
to the right.
