Torque limitation option
The limitation of the torque is separate for both setting directions via a
potentiometer each which can be set from 0 to maximum value. On reaching
the torque limit a signal with U = U
nenn
is given via terminal 26. The signal can
take a maximum load of 0.1 A.
After addressing the torque limit - as long as the control signal lasts - the
expected torque is checked every 8s. In case of fall off, the preselected value
is readjusted by briefly switching on the motor.
Reset option in case of power cut
In the case of a power cut, rotary actuators with integrated emergency power
supply automatically drive the setting element to a defined limit position. The
resetting in the case of a power cut includes the torque limit.
Torque limitation option
(see diagram inside cover)
Potentiometer 1 Setting the max. torque for setting direction "Closed",
infinitely variable from 0 to rated torque
Potentiometer 2 Setting the max. torque for setting direction "OPEN",
infinitely variable from 0 to rated torque.
