Torque control macro

This macro is used in applications in which torque control of the motor is required.
Torque reference is given through analog input AI2, typically as a current signal in the
range of 0...20 mA (corresponding to 0...100% of rated motor torque).
The start/stop signal is connected to digital input DI1. The direction is determined by
DI2.
Through digital input DI3, it is possible to select speed control instead of torque
control. It is also possible to change the control to local (control panel or PC tool) by
pressing the Loc/Rem key. By default, the local reference is speed; if a torque
reference is required, the value of parameter
changed to Torque.
A constant speed (by default, 300 rpm) can be activated through DI4. DI5 switches
between acceleration/deceleration time sets 1 and 2. The acceleration and
deceleration times, as well as ramp shapes, are defined by parameters
23.12...23.19.
