Delta Electronics VFD-F Series manual AVI Minimum Voltage

VFD-F Series

In noisy environments, it would be advantageous to verify the terminal status several times before executing a new command, nearly eliminating false signals.

Example: If Pr.04-08 is set to 4, the AC drive will confirm the terminal status (4+1 = 5) 5 times before a change is made. This correlates to an 8~10msec time response from input command to execution.

It is not recommended to set this parameter to 00, since interference may cause improper operation of the AC drive.

The above parameters are used to set the analog input reference values. The min and max frequencies are based on Pr.01-00 (during open-loop control) or the PID reference value Pr.10-01 (during PID close-loop control).
