If the adjusted torque is reached the actuator
cannot drive into the same direction. You must first
drive the actuator in the other direction. That
means that a reduction of the torque after a torque
switch off, the actuator will not drive into the same
direction. That is necessary for non self locking
actuators
P2.5 Torque Boost Open
0 – 120%
{0%}
Increase the torque during motor start (approx. 0.5
sec) in direction OPEN. On large flywheel masses
a unwanted shut off can be avoided. Furthermore,
break free effect can thus be achieved. When
setting values are less than the switch off torque in
OPEN direction (P2.1) there will be no torque
increasing during motor start.
The torque increase should occur only if the valve
is designed for it!
P2.6 Torque Boost Close
0 – 120%
{0%}
As P2.5 but in CLOSED direction.
P2.7 Torque Hysteresis {0: 50%}
After a torque shut off the current torque must be
reduced by at least the hysteresis to enable the
actuator to drive in the switch off direction.
1: 25%
2: 12%
3: 6%
4: 3%
5: 1%
When installing the actuator on an additional gear, please take into account the correspond-
ing values of the gear / thrust unit as you enter the actuator parameters. To achieve an
effective output torque (incl. gear) / output power (including thrust unit) ratio, the factor
gear/thrust unit must be considered.
