5.3.5.9 - prevailling torque phase
Prevailling torque phase is not available in
ERPHT mode.
This phase allows you to monitor the load moment
(prevailing torque) of a screw or nut.
The initial time out (expressed in time or angle) allows
you to eliminate the shock pulse when starting the motor
and the mechanism.

Max.time
Phase running time out: 0.01 - 99 s.
Int.time
Time programmed between this phase
and the next one: 0 - 20 s.
target A
Target angle: 0 - 9,999°.
Min t
Minimum torque: 0 Nm to max. value
of the spindle.

Yes / No
external stop
Yes / No - The following conditions
must be met for the system to stop
the current phase and shift to the next
one:
● The External Stop parameter must
be on Yes in this screen.
● The signal at the External Stop
input of the Input/Output connector
must shift to 1.
prevailing
offset
Ignore / Add (to the measurement) /
Subtract (from the measurement).
The average value of the prevailing
torque is used as an offset, to be
added to or subtracted from the
measurement in the next phases.

page 57 (torque, angle, angle + torque
and prevailing torque).
