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).
