PARAMETER
2.15.3 Reference of terminal FM/AM, terminal AM0/AM1 (FR-A7AY), terminal DA1 (FR-
A7AZ) [Pr. 55, 56, 291 * , 839*, 866 * , 867*]
(common)
Two types of monitor outputs are available in
: pulse train output from terminal FM and
analog voltage output from terminal AM. Analog voltage
output (terminal AM0) and analog current output (terminal
AM1) become available when the plug-in option FR-A7AY
is mounted. Bipolar analog voltage output (terminal DA1)
becomes available when the plug-in option FR-A7AZ is
mounted to
. Terminal FM for pulse output is
available for monitor output in . Analog
voltage output (terminal AM0) and analog current output
(terminal AM1) become available when the plug-in option
FR-A7AY is mounted to . For , pulse train
output by voltage output and by open collector output can
be selected for terminal FM.
Set the reference of the signal output from terminal FM and
AM, AM0, AM1, DA1.
