This parameter once changed, will become operational only when power stage is disabled.
**These parameters once changed, must be saved. The new value assigned to this parameter will become operational only
after a power reset.

ONFIGURATIONS
To control the motor torque through AZ3s, mode of operations must be set to 4 as defined in DS402
specification. In order to make operative the change in operating mode, power stage must be
disabled (refer to chapter 5.4).
Target torque is the torque set point and can be modified through CAN or Modbus, analog inputs
(refer to chapter 4.4) and digital inputs (refer to chapter 4.5).
Torque slope permits to modify the torque linear ramp, it must be set according to the time within
which the operating torque is to be reached (torque ramp block in the image below).
Max torque indicate the maximum value of Target torque configurable. Max current defines the
maximum current that can be generated in function of the configured Target torque (torque limits
block in the image below).
