FIG. 10 – STOP COMMAND C. "STOP" (STP) — Use
a nor-mally closed
(NC) contact between
terminals "STP" and
"RTN." Opening the
contact activates the
control’s Dynamic
Brake producing a
rapid stop. (Note: A
normally open (NO)
limit switch or contact
can also be used to
activate the stop com-
mand. To use a (NO)
contact move jumper
JS to the "NO" position). (See table 3, p. 7.)
Application Note:
The setting of jumper "JW" establishes the priority a "STOP" command has over a "RUN"
command. If jumper "JW" is placed in position "S," the "STOP" command has priority over
the "RUN". If the "STOP" is activated (contact open), the control cannot be started with the
"START" command. If jumper "JW" is in the "R" position (factory setting), the "RUN"
command has priority over the "STOP." In this mode of operation the control can be
started with the "RUN" command even though the "STOP" is activated (contact open).
This setting of jumper JW in the "R" position is used for cycle on demand applications.
See table 8 for detailed information of jumper "JW" operation. Warning! Do not use as
safety stop. See Safety Warning on page 2.
TABLE 8 – JUMPER "JW" OPERATION
JUMPER "JW" SETTING DESCRIPTION CIRCUIT OPERATION
“R”
(Factory
Setting)
"Run" has priority
over "Stop." Control
will run even if stop
contact is open.
*(Use this setting for
"Cycle on Demand "
operation.) When start contact
is made, control
will run with “STP”
open. If “STP” is
closed and then
reopened, control
will stop.
“S”
"Stop" has priority
over "Run." Control
will run only when
“STP” contact is
closed. When start contact
is made, “STP”
contact must be
closed for control
to run.
D. "RETURN" (RTN) – When Jumper "JR" is moved to position "O" from the factory
setting "F" it disables all of the command functions (Run, Jog, Stop, etc.). To enable
these functions a contact must be placed between the "RTN" and "COM" terminals.
Note: Opening the return control will not stop the indexer, if opened while indexer is
running.
Warning! Do not use as emergency or safety stop. See Safety Warning on page
2. See fig. 11, p. 14, for jumper "JR" operation. Failure to follow the Safety
Warning Instructions may result in electric shock, fire or explosion.
