Symbol Terminal name
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.
Intelligent input
PLC Jumper terminals P24 and PLC for the sink logic; jumper terminals CM1
(common)
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.
Select five of a total 51 functions, and assign these five functions to
11
terminals 11 to 15.
12
If you have selected an alarm code using the function "C062", terminals 11
13 Intelligent output
to 13 or 11 to 14 are used exclusively for the output of cause code for alarm
14
(e.g., inverter trip). The control logic between each of these terminals and
15
the CM2 terminal always follows the sink or source logic.
Intelligent output This terminal serves as the common terminal for intelligent output terminals
CM2
(common) [11] to [15].
Select functions from the 43 available, and assign the selected functions to
these terminals, which serve as C contact output terminals.
AL0
Intelligent relay
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.
