6.4.4 Analog Torque Input Scaling

The analog voltage between T_REF and GND controls the motor torque command. Using
with parameter P1-41 can adjust the torque control ramp and its range.

In Torque mode, this parameter is used to set the maximum analog torque
command based on the maximum input voltage (10V).
In Position (PT, PR) and Speed mode, this parameter is used to set the maximum
analog torque limit based on the maximum input voltage (10V).
For example, in torque mode, if P1-41 is set to 100 and the input voltage is 10V, it
indicates that the torque command is 100% rated torque. If P1-41 is set to 100, but
the input voltage is changed to 5V, then the torque command is changed to 50%
rated torque.
Torque Command / Limit = Input Voltage Value x Setting value of P1-41 / 10
