RS-485(Modbus-RTU),Di/Do

Pulse input

Analog voltage input

Analog voltage input

Two RS-485 ports (for parameter editing and monitor)

Our original protocol Modbus-RTU

9600/19200/38400 bps, connection of max. 31 axes

Pulse input under position control
Differential input: max. input frequency ≤ 1.0MHz
Open collector input: max. input frequency ≤ 200kHz
(in case of signals at 90-degree phase difference, the above relationship is true for the four-fold frequency.)

Pulse format
·Command pulse/Command direction
·Forward/Reverse pulse
·Two signals at 90-degree phase difference
Select one of these formats with a parameter setting.

Pull-up power input at open collector input
