] 10 (Depends on the Motor type. Refer to “2.5. Motor Specifications.”)
Positioning operation mode
Program operation (256 program channels), Pulse train command, RS-232C
serial communication command, Jogging, Home Return
Pulse train command
Photo coupler input. Maximum frequency 1 MHz
Input format: CW/CCW, Pulse & direction or øA/øB
Resolution changer for free manipulation is available.
(1000 to 5 242 880 [count/revolution])
Input signal
Control input
Photo coupler (± common), 17 input ports. Input voltage: 24 VDC
Emergency stop, Alarm clear, Over travel limit + direction, Over travel limit –
direction, Servo ON, Program operation start, Stop, Internal program channel
switching 0 to 7, Jog, Jog direction, (Hold, Velocity override, Integration OFF,
Home Return start, and Home position limit)
*1
Position feedback
signal
Signal format: øA/øB/øZ line driver. Free resolution setting to øA/øB is
available.
Resolution of øA/øB:
Shipping set: 20 480 [count/revolution] (Quadrupled: 81 920 )
Maximum: 1 310 720 [count/revolution] (Quadrupled: 5 342 880)
*Because the maximum frequency is 781 [kHz], the setting of the resolution
limits the maximum rotational speed. (Max. velocity = 781 [kHz]/
resolution of øA (øB)
Resolution of øZ: 80 [count/revolution]
Output
signal
Control output
Photo coupler (± common), 8 output ports.
Max. switching capacity: 24 VDC/50 [mA]

*1: Change of function assignment of the Input/Output ports will make these functions effective.
*2: These control outputs become effective when these function is assigned to the output port.
