PLC
Intelligent input
(common)
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
circuit terminal block.
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.

Intelligent output
Select five of a total 51 functions, and assign these five functions to terminals 11
to 15.
If you have selected an alarm code using the function "C062", terminals 11 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 the CM2
terminal always follows the sink or source logic.
Voltage drop between each
terminal and CM2 when
output signal is on: 4 V or less
Maximum allowable voltage:
27 VDC
Maximum allowable current:
50 mA
CM2
Intelligent output
(common)
This terminal serves as the common terminal for intelligent output terminals [11]
to [15].

output
Select functions from the 43 available, and assign the selected functions to these
terminals, which serve as C contact output terminals.
In the initial setting, these terminals output an alarm indicating that the inverter
protection function has operated to stop inverter output.
(Maximum contact capacity)
AL1-AL0: 250 VAC, 2 A
(resistance) or 0.2 A
(inductive load)
AL2-AL0: 250 VAC, 1 A

External
thermistor input
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.
[Recommended thermistor properties]
Allowable rated power: 100 mW or more
Impedance at temperature error: 3kΩ
The impedance to detect temperature errors can be adjusted within the range 0Ω
to 9,999Ω.
Allowable range of input
voltages
0 to 8 VDC

(3) Explanation of switch
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 2-10.
