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: r/min
Range: 0 ~ 10000
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 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 x setting/10
