Chapter 9

A rectifier IOC condition is considered to be redirectable if it occurs more than

1 minute after the rectifier starts running. Any rectifier IOC condition occurring

within 1 minute of a rectifier start is always reported as a rectifier IOC fault; it is

assumed that these faults are caused by conditions within the drive and not by

events on the AC line.

The number of redirects allowed and the amount of time allowed for them before

the redirection is discontinued are controlled by rectifier parameters 300 and

301. The default parameters are five redirects allowed in 24 hours.

Once redirection has been discontinued, it remains discontinued until the drive

is power cycled or until a time equal to the value of IOC Redir Time (300) has

gone by since the last redirectable event.

• Redirection can be turned off (disabled) by setting IOC Redir Max (301)

to 0.

• Redirection can be turned on (enabled) by setting IOC Redir Time (300)

to 0 and IOC Redir Max (301) to a nonzero value.

Number of rectifier Instantaneous Overcurrent (IOC) events that can occur

before IOC fault redirection is disabled.

See rectifier parameter 300 for a description of the rectifier IOC fault redirect

facility.

This parameter is for use by service personnel only.
