(1)
Various signals such as Inverter Running, Frequency Arrival
and Overload Early Warning can be output from these
terminals by setting function code E20 to E24. Refer to
Chapter 5 "FUNCTION CODES" for details.
(2)
The operating mode between transistor output terminals [Y1]
to [Y4] and terminal [CMY] can be switched to "ON at signal
output (active ON)" or "OFF at signal output (active OFF)."

Figure 2.2-26 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, 100 mA max.) through the [PLC] terminal.
Short-circuit between the terminals [CMY] and [CM] in
this case.
