SYSTEM STATUS IN MULTIMACHINE - MULTIARM CONFIGURATION
Below is an example in which the controller handles two MACHINES and three ARMS. This example does
not cover all the possible configurations, but it shows the statuses of the controller in multi-machine -
multiarm handling.
·
MACHINE 1: composed of two ARMS (ARM1 and ARM2)
·
MACHINE 2: composed of one ARM (ARM3)
PROG Status
If movement of ARM1 has been selected using the ARM key on PTU4, when the DRIVE ON key on PTU4 is
pressed, the power contactor will close, thereby powering the drives concerning MACHINE 1. In this case it
will only be possible to move the axes which form ARM1, ARM2 is disabled.
The power contactor of MACHINE 2 (ARM3) is open.
AUTO Status (local-remote)
This is distinguished by two cases:
·
Management without the IOMs module (inserted in the CONTROL UNIT rack):
when the DRIVE ON key on the PTU4 is pressed, the power contactors are closed which supply the
drives concerning MACHINES 1 and 2; all the axes which form the three ARMS are enabled (motors on).
· Management with the IOMs module (inserted in the CONTROL UNIT rack):
when the DRIVE ON key on the PTU4 is pressed, it is possible to activate both machines; or from the
remote panel (managed by the IOMs module) MACHINE 1 (MOTOR ON - MACHINE 1)orMACHINE 2
(MOTOR ON - MACHINE 2).
Then, depending on the case, both power contactors are closed which supply the drives of MACHINE 1 and 2;
or activating MACHINE 1 (MOTOR ON - MACHINE 1)orMACHINE 2 (MOTOR ON - MACHINE 2) from the
remote panel, the respective power contactor will be closed which supplies the drives of the machine selected.
The DRIVE ON, DRIVE OFF, START and HOLD commands (on PTU4) or MOTOR ON,
MOTOR OFF, RUN and STOP commands (on the remote panel) further decide the control-
ler status.
Examples:
·
If the MOTOR OFF - MACHINE 1 key is pressed on the remote panel: when the DRIVE
ON key on PTU4 is pressed only MACHINE 2 will be activated.
·
Vice versa, if the DRIVE OFF key on PTU4 is pressed: when the MOTOR ON -
MACHINE 1 or MOTOR ON MACHINE 2 keys are pressed both machines are not
activated.
