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.
Relevant parameters:
P1 - 40▲
VCM

Max. Analog Speed Command / Limit

Default: rated speed
Applicable Control Mode: S/T
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 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 x setting/10
