Set the Logic Controller in par. LC-00
Logic Controller Mode
to ON.
Start / stop command is applied on terminal 18. If stop signal is applied the frequency converter will decel and go into free mode.
8.1.12 Torque Control Open Loop
A conveyor belt is feeding bales forward into a shredder at constant force,
regardless of the conveyor speed. If there is a space between the bales the
conveyor belt must move the next bale to the shedder as fast as possible.
Optimisation of the torque control After setting the basic settings the factory
setting is optimised for most processes. It is rarely necessary to optimise
the
torque proportional gain
in par. PI-12 and the torque integration time in
par. PI-13.
Feedback
The feedback signal is an estimated torque, calculated by the frequency con-
verter on the basis of the current values measured.
Reference
The reference is in Nm. A minimum and a maximum reference can be set (par.
AN-14 and AN-15) which limit the sum of all references. The reference range
cannot go beyond the feedback range.
Speed limit function
Speed limit can be set in par. AN-20 to AN-25.
