Chapter 3 Configuring the Option Module
Setting the Fault Configuration Parameters
When setting
Host Parameter 33 - [Comm Flt Action], 34 - [Idle Flt Action]
or 36 - [Msg Flt Action] to ‘Send Flt Cfg’, the values in the following parameters
are sent to the drive after a communication fault, idle fault, and/or explicit
messaging for drive control fault occurs. You must set these parameters to values
required by your application.
Changes to these parameters take effect immediately. A reset is not required.
Resetting the Option Module Changes to switch settings and some option module parameters require you to
reset the option module before the new settings take effect. You can reset the
option module by power cycling the drive or by using
Device Parameter 14 -
[Reset Module] .
Set
Device Parameter 14 - [Reset Module] to ‘1’ (Reset Module).
When you enter ‘1’ (Reset Module), the option module will be immediately reset.
An alternate method to reset the module is by power cycling the drive. When you
enter ‘2’ (Set Defaults), the option module will set all of its
Device and Host
parameters to their factory default values. (This is the same as pressing the ALL
soft key when using the MEMORY folder method described in
Restoring Option
Module Parameters to Factory Defaults on page 33 .)
Option Module Host Parameter Description
Parameter 37 - [Flt Cfg Logic] A 32-bit value sent to the drive for Logic Command.
Parameter 38 - [Flt Cfg Ref] A 32-bit REAL (floating point) value sent to the drive for Reference.
Parameter 39 - [Flt Cfg DL 01]
through
Parameter 54 - [Flt Cfg DL 16]
A 32-bit integer value sent to the drive for a Datalink. If the destination of the
datalink is a REAL (floating point) parameter, you must convert the desired
value to the binary representation of the REAL value. (An internet search of
‘hex to float’ provides a link to a tool to do this conversion.)
ATTENTION: Risk of injury or equipment damage exists. If the option module is
transmitting control I/O to the drive, the drive may fault when you reset the
option module. Determine how your drive will respond before resetting the
option module.
