PROCEDURES FOR COMMAND ACTIVATION WITH THE CONTROLLER IN
AUTOMATIC REMOTE STATUS
The controller manages motor start/stop and cycle start/stop commands with the DRIVE ON/OFF and
START/HOLD commands coming from the external equipment after checking congruence and safety condi
-
tions.
DRIVE ON PROCEDURE
Remote activation of the DRIVE ON procedure makes it possible to activate the motors when the DRIVE ON
signal is active if all the system checks have been passed. This procedure is activated only if the status se
-
lector on the operator panel is in the Automatic Remote position .
The DRIVE ON request to the system must be performed at least 4 seconds after the
last DRIVE OFF because of hardware behaviour of the dynamic braking device
(C3G-DBU3) installed on the control unit.
1. On the controller:
- the main power switch must be in the ON position;
- the status selector must be in the Remote position .
- relays K16/SIM (LOCAL
/REMOTE pin 11 on X30) and K17/SIM (ALARM pin 29 on X30) are closed.
In the case of an error, all the output relay contacts of the SIM module remain open.
2. On the remote control panel if the timeout counter has not expired:
-
if the status of relay K10 of the SIM module (pin 8 on X30) is OFF (DRIVE ON/OFF
);
-
if the power contactors are open (POWER CONTACTOR 1 Pin 52-53 X30, POWER CONTACTOR 2
Pin 55-56 X30) (if the second machine is present POWER CONTACTOR 1 PIN 52-53/X30-2, POWER
CONTACTOR 2 PIN 55-56/X30-2);
-
if no alarm is present (ALARM
pin 29 on X30 closed);
the DRIVE ON COMMAND is activated (pin 1 on X30).
3. On the controller, if the following conditions are found:
-
DRIVE ON (pin 1 on X30) active (true);
-
DRIVE OFF
(pin 19 on X30) active (true);
-
START (pin 2 on X30) not active (false);
-
HOLD
(pin 20 on X30) active (true);
the DRIVE ON procedure is performed; otherwise relay K17/SIM is opened which generates an alarm
signal (pin 29 on X30).
At the end of the DRIVE ON procedure, relay K10/SIM (DRIVE ON/OFF
pin 8 on X30) is closed with ro

bot powered.
