Chapter 3 Configuring the Option Module
Setting the Fault Configuration Parameters
When setting Host Parameters 33 - [Comm Flt Action] and 34 - [Idle Flt
Action] to ‘Send Flt Cfg’, the values in the following parameters are sent to the
drive after a communication fault and/or idle 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 07 -
[Reset Module] .
Set Device Parameter 07 - [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 35 ). After performing a Set
Defaults, you must enter ‘1’ (Reset Module) or power cycle the drive so that the
new values take effect. Thereafter, this parameter will be restored to a value of ‘0’
(Ready).
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.
