drive. For additional information see the
Advanced User Guide
.
12.22.1 Reference modes
If Pr
8.39
is set to OFF (0), then the setting of Pr
1.14
automatically
changes the operation of digital inputs T28 and T29 by configuring the
destination parameters Pr
8.25
and Pr
8.26
. To allow Pr
8.25
and Pr
8.26
to be changed manually by the user, the automatic set-up must be
disabled by setting Pr
8.39
to 1.
If Pr
8.39
is 0 and Pr
1.14
is changed, then a drive reset is required
before the function of terminal T28 or T29 will become active.
* Setting Pr
1.15
to 9 enables the Preset reference scan timer. With the scan timer enabled the preset references are selected automatically in turn.
Pr
1.16
defines the time between each change.
** Jog forward can only be selected when the drive is in either the ready (rdy), inhibit (inh) or trip states.
