6.3.4 Analog Speed Input Scaling

The analog voltage between V_REF and GND determines the motor speed command.
Using with parameter P1-40 (Max. Analog Speed Command) can adjust the speed control
ramp and its range.

In Speed mode, this parameter is used to set the maximum analog speed command
based on the maximum input voltage (10V).
In Torque mode, this parameter is used to set the maximum analog speed limit
based on the maximum input voltage (10V).
For example, in speed mode, if P1-40 is set to 3000 and the input voltage is 10V, it
indicates that the speed command is 3000r/min. If P1-40 is set to 3000, but the
input voltage is changed to 5V, then the speed command is changed to 1500r/min.
Speed Command / Limit = Input Voltage Value x Setting value of P1-40 / 10
