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
PT
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
