E27 is the parameter. Should be set to 99 Alarm Output (for any alarm). Contacts 30B and 30C are Normally Closed mechanical contacts. When the VFD has an alarm, the contact will open. So run wire from PLC (Digital Input power 24v DC) to Terminal 30C, then run another wire from 30B to Digital Input 0 on PLC. Then tell PLC when Digital Input 0 is True (1) trigger a coil for alarm. Hopefully this is what you where looking for.
@@alfredoduran3946 When I do it as you say, it sends 24 volts to the plc continuously when the driver is running or not. I want host c and b not to pull when there is an error. for example when the drive is not powered or other problems
Ok. Then you want to use 30A and 30C since 30C is common. So the contact on the VFD will be always open and when the VFD alarms, it will close and then send 24v dc to your digital input and then you can trigger a digital output from your digital input to alarm you via a red light or buzzer, etc…

thanks for telling
How to communicate 2 drive
Hi
Can you help me with the communication setting between fuji inverter and delta HMI and the addresses of the inverter to input in the HMI
hello, I want to send an alarm signal to plc when the driver fails, what is the parameter? can you help me (30a,30b,30c)
