(1) Various signals such as inverter running, frequency arrival
and overload early warning can be assigned to terminals [Y1]
to [Y4] by setting function code E20 to E23. Refer to Chapter
6 "FUNCTION CODES" for details.
(2) It is possible to switch the logic value (1/0) for ON/OFF of the
terminals between [Y1] to [Y4], and [CMY]. If the logic value
for ON between [Y1] to [Y4] and [CMY] is 1 in the normal
logic system, for example, OFF is 1 in the negative logic
system and vice versa.

Figure 2.9 shows examples of connection between the control
circuit and a PLC.
•
When a transistor output drives a control relay,
connect a surge-absorbing diode across relay’s coil
terminals.
•
When any equipment or device connected to the
transistor output needs to be supplied with DC power,
feed the power (+24 VDC: allowable range: +22 to
+27 VDC, 200 mA max.) through the [PLC] terminal.
Short-circuit between terminals [CMY] and [CM] in
this case.
