The input pulse frequency is 200kHz; if the local 24V power supply (it only can provide 100mA
current) or the 12~24V power supply provided by the user is used, it is required to connect to
current-limiting resistor R(the resistance is selected as the below table).

For all the 3 methods, shielded twisted-pair must be used and the length should be less than 3m.

There are three analog input circuits, AD1, AD2 and AD3, precision of AD1 is 16-bit (optional for
standard models), precision of AD2 and AD3 is 12-b
it (standard). The input impedance is 10kΩ.
The input voltage range is -
10V~+10V. If the voltage is higher than ±11V, the circuits may be
damaged.
If the non-standard model is used as the speed control, AD1 channel is invalid, please take AD3
as the speed command input
terminal and modify P3.70 to “speed command”.
