Symbol	Terminal name	Description
		To switch the control logic between sink logic and source logic, change the
		jumper connection of this (PLC) terminal to another terminal on the control
PLC	Intelligent input	circuit terminal block.
	(common)	Jumper terminals P24 and PLC for the sink logic; jumper terminals CM1
		and PLC for the sink logic.
		To use an external power supply to drive the contact inputs, remove the
		jumper, and connect the PLC terminal to the external interface circuit.
11		Select five of a total 51 functions, and assign these five functions to
		terminals 11 to 15.
12
		If you have selected an alarm code using the function "C062", terminals 11
13	Intelligent output
14		to 13 or 11 to 14 are used exclusively for the output of cause code for alarm
		(e.g., inverter trip). The control logic between each of these terminals and
15
		the CM2 terminal always follows the sink or source logic.
CM2	Intelligent output	This terminal serves as the common terminal for intelligent output terminals
	(common)	[11] to [15].
		Select functions from the 43 available, and assign the selected functions to
AL0	Intelligent relay	these terminals, which serve as C contact output terminals.
AL1	output
AL2		In the initial setting, these terminals output an alarm indicating that the
		inverter protection function has operated to stop inverter output.
		Connect to an external thermistor to make the inverter trip if an abnormal
		temperature is detected.
		The CM1 terminal serves as the common terminal for this terminal.
TH	External	[Recommended thermistor properties]
	thermistor input	Allowable rated power: 100 mW or more
		Impedance at temperature error: 3kH
		The impedance to detect temperature errors can be adjusted within the
		range 0H to 9,999H.

(3)Explanation of switch settings

The internal slide switch (SW1) is used to enable or disable the emergency stop function (the function is disabled by factory setting).

* For the location of the slide switch, see page 2-9.
