Auxiliary Axis Contactor Monitor

Auxiliary Axis Contactor 

(Emergency Stop)

 

Figure 4-10: Auxiliary Axis Contactor and Monitoring (CN3 - FIO04 Connections) 

The auxiliary axis or emergency stop contactor is driven by a safety output on the PCSS unit, 
(as shown in

 Figure 4-10 

for the FIO04) which is used to control the emergency stop circuit 

requirements of the press brake.  This ensures that should an emergency stop condition occur, 
any associated press brake operation is disabled and that any control or movement of the 
pressing beam is prevented.   

When the PCSS is initially powered up and providing certain conditions are met for normal 
operation, this output is can be switched on by pressing the error reset switch connected to the 
PCSS, allowing all operational circuits for the press brake to be enabled.  In the event that an 
emergency stop condition arises, the auxiliary axis or emergency stop contactor is switched off 
by the safety output on the PCSS. The emergency stop condition must then be resolved and 
the error reset switch pressed to activate the safety output for the auxiliary axis or emergency 
stop contactor. 

When connecting the emergency stop or auxiliary axis contactor to the Y07 output of CN3 it is 
also important to install a diode in reverse polarity across the coil as shown in 

Figure 4-10

 

This prevents the contactor from de-energising during the hardware checks that are performed 
on this output after the completion of a bend cycle due to the increased release time of the 
contactor provided by the diode.  The rating of the diode installed should be sufficient to handle 
the supply current for the contactor. 

A normally closed (NC) contact from this contactor is also required to be connected to the 
safety input of the PCSS, as shown in 

Figure 4-10

.  This is important in monitoring that the 

changeover of this contactor occurs correctly.  When an emergency stop condition happens, 
monitoring of the contactor is essential in confirming that the contact changeover occurs within 
an acceptable time limit to ensure that press brake operation is disabled.
