04 - 04 Digital Input Terminal Response Time

Settings 01~20Factory Setting: 01

This parameter selects the response time of digital input terminals MI1 to MI4, EF and FWD. AC drive will scan the digital input terminals once every 2msec. During each scan the drive will check the status of each terminal (open or closed).

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.04-04 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.
