5.6 Encoder and Sync Switch Installation
5.6.3 Sync Switch Specifications
General
The sync signal (synchronization signal, sometimes called start signal) is used to
enter the position of the work object on the conveyor into the robot control system.
The sync signal is entered by installing a sync switch on the conveyor. The sync
switch will detect each object as it passes the switch.
LEDs labelled Start 1 / 2 (Start 1 and Start 2) for sync switch 1 (and sync switch 2 if
two sync switches are installed) indicating the operation of the sync switch are
present on the control cabinet LED display.
Switch Specification
The sync switch should be selected so that it provides a reliable and repeatable
signal for the work objects on the conveyor, regardless of conveyor speed. The
switch arrangement must be designed so that it only gives one signal for each work
object, and that it does not give any signal if the work object should happen to pass
the switch in backwards direction. (If the switch gives multiple signals when an
object passes, the parameter SyncFilter can be set so that only one signal is
accepted. For information, see ‘Operator’s Manual, IRC5P’).
Switch Types
Different types of switching devices may be used. Most common is a limit switch,
but photocell with switch output or Namur initiator etc. may also be used.
Switch Location
The sync switch may be installed in the hazardous area of the spray booth or in the
non-hazardous area outside the spray booth. Different requirements apply to the
switch and its connection to the control system in these situations. For information,
see ’Sync Switch Connection - General Information’ on page 95.
