[1] Analog input
The motor speed can be controlled by applying -10V~10V voltage
between analog speed input terminals (AD1, GND, pin “1” and “5”)
of CN1. In the factory default, the positive value means the forward
direction and the negative value means the reverse direction.
The direction of analog speed command can be changed by P0.41.
Please refer to the detailed instruction of P0.41.
2 Bus input
The speed command from upper PC can be received by the
interface of communication bus. When P4.10 is 1, the motor speed
can be changed by P4.13.
Please refer to the detailed instruction of P4.10 and P4.13.

1. Suppose the analog input 1 function selection is speed command.
2. The voltage of the analog speed command input corresponds to the changing gain of the
motor command speed.
3. The relation between analog speed command input voltage and the speed, the default value
is that each 1V corresponds to 100r/min.
Analog speed command = Input voltage x P0.42
