5.2.2 Basic parameters
P102 Acceleration time RF
Setting range 0.00 ... 25.50 s
Other applicable parameter(s): P130, P216
Factory setting { 1.00 }
Description The acceleration time is the time that the drive needs to reach the maximum speed
after receiving the enable. Since the acceleration time is determined by the phase
control variation, it is only a case of indirect control of the acceleration time here. The
actual acceleration time of the motor essentially depends on the motor which is used,
the inertial masses and the counter-torque.
Note As long as parameter P130 =0 is set, the acceleration time is determined via
potentiometer P4 . In this case the parameter can only be read, but not changed. It
then corresponds to the setting determined by the potentiometer.
If the motor is idling or in the case of drives with extremely low counter-torque, the soft
start should be selected. Because the inertial masses and the counter-torque are
disproportional, the phase control procedure cannot control the drive properly. The
drive unit and its surroundings may be subjected to unwanted mechanical loads
(vibration or the like).
P103 Run-down time RF
Setting range 0.00 ... 25.50 s
Other applicable parameter(s): P107, P108, P130
Factory setting { 1.00 }
Description The run-down time is the time that the drive needs to reach a speed of "0" after the
enable has been removed. Since the run-down time is determined by the phase
control variation, it is only a case of indirect control of the run-down time here. The
actual run-down time of the motor essentially depends on the motor which is used, the
inertial masses and the counter-torque.
Note As long as parameter P130 =0 is set, the run-down time is determined via
potentiometer
P4
. In this case the parameter can only be read, but not changed. It
then corresponds to the setting determined by the potentiometer.

P107 Brake reaction time FL
Setting range 0.00 ... 25.50 s
Other applicable parameter(s) P103, P108
Factory setting
{ 0.00 }
Description Time delay for the application (closing) of an electro-magnetic brake after the run-
down time has been reached ( P103 ) or the enable removed.
Once the motor starter has blocked its voltage at the output, a connected mechanical
brake remains open until the time set in P107 has elapsed. This allows the motor to
reduce its speed or even stop before the brake is applied.
Note In switch off mode 4 (DIP switch S1-DIP3/4) the application time of the brake is
determined by parameter
P103
/Potentiometer P4.
Depending on the reaction time of the brake, the motor can be expected to switch off
before the brake is applied. For lifting equipment applications, this means that there is
a risk of the load dropping at the time of stopping.
