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 3000 r/min. If P1-40 is set to 3000, but the input
voltage is changed to 5V, then the speed command is changed to 1500 r/min.
Speed Command / Limit = Input Voltage Value x Setting value of P1-40 / 10
