About the inverter function
12.25 What you can achieve by
externally outputting signals
12.25.1 Using the output signal function
externally
• I want to detect warning signals, error signals, and
state signals issued by the inverter with an external
system.
• Output terminals 11 to 15 are used for open
collector output, and Relay output terminals 16 and
17 are used for relay output. Relay output 16
serves as a contact a relay, and Relay output 17
serves as a contact c relay.
Parameters
Terminals corresponding to parameters
• To use the contact c relay, please check the control
circuit power supply and the relay output terminals
whether they are turned on or off.
• For the content of an output signal, by allocating
the functions that you want to output to [CC-01] to
[CC-07], you will be able to allow the
corresponding output terminal contacts to operate.
• You can switch an output signal level with the
Contacts a/b selection functions of [CC-11] to
[CC-17].
