P24	+24V for logic inputs	24VDC, 100mA. (do not short to terminal L)
PLC	Intelligent input common	To change to sink type, remove the jumper
		wire between [PLC] and [L], and connect it
		between [P24] and [PLC]. In this case,
		connecting [L] to [1]~[7] makes each input
		ON. Please remove the jumper wire when
		using external power supply.
1	Discrete logic inputs	27VDC max. (use PLC or an external supply
2	(Terminal [3],[4],[5] and [7]	referenced to terminal L)
3/GS1	have dual function. See
4/GS2	following description and
5/PTC	related pages for the details.)

7/EB
GS1(3)	Safe stop input GS1	Functionality is based on ISO13849-1
GS2(4)	Safe stop input GS2	See appendix for the details.
PTC(5)	Motor thermistor input	Connect motor thermistor between PTC and
		L terminal to detect the motor temperature.
		Set 19 in C005.
EB(7)	Pulse train input B	2kHz max.
		Common is [PLC]
EA	Pulse train input A	32kHz max.
		Common is [L]
L (in upper row) *1	GND for logic inputs	Sum of input [1]~[7] currents (return)
11/EDM	Discrete logic outputs [11]	50mA max. ON state current,
	(Terminal [11] has dual	27 VDC max. OFF state voltage
	function. See following	Common is CM2
	description and related pages	In case the EDM is selected, the functionality
	for the details.)	is based on ISO13849-1
		4VDC max. ON state voltage depression
12	Discrete logic outputs [12]	50mA max. ON state current,
		27 VDC max. OFF state voltage
		Common is CM2
CM2	GND for logic output	100 mA: [11], [12] current return
AM	Analog voltage output	0~10VDC 2mA maximum
EO	Pulse train output	10VDC 2mA maximum, 32kHz maximum
L (in bottom row) *2	GND for analog signals	Sum of [OI], [O], and [H] currents (return)
OI	Analog current input	4 to 19.6 mA range, 20 mA nominal,
		input impedance 100 Ω
