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.

Analog Input Voltage (V)
The speed control ramp is
determined by parameter P1-40

Applicable Control Mode: S/T Section 6.3.4, P1-55
Unit: rpm
Range: 0 ~ 5000
Settings:
In Speed mode, this parameter is used to set the speed at the maximum input voltage (10V) of
the analog speed command.
In Torque mode, this parameter is used to set the speed at the maximum input voltage (10V) of
the analog speed limit.
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 3000rpm. If P1-40 is set to 3000, but the input voltage is changed to 5V,
then the speed command is changed to 1500rpm.
Speed command / limit = Input voltage x setting/10
