This parameter defines the type of contact of side door switch connected to the digital input of PLC.

This parameter is available, only if Safety option(in PLC options) is OFF and Side Door is '1 input' (if 2 input is selected, left door and right door parameters appear separately) . By hardware, the left and right door switches are merged together and connected as single input to PLC. The internal function of PLC uses this input to stop the Y-axis, when any one of the side door is opened, and the corresponding error message appears on the screen.

This parameter defines the type of contact of rear door switch connected to the digital input of PLC.

The internal function of PLC uses this input to Emergency stop and cut off the hydraulic pump, when rear door is opened, and the corresponding error message appears on the screen.

This parameter defines the contact type Oil low level feedback connected to digital input of PLC.

Based on this input RA control obtains the status of Oil level.

This parameter defines the contact type Oil high level feedback connected to digital input of PLC.

Based on this input RA control obtains the status of oil level.

This parameter defines the type of contact of oil temperature working range switch connected to the digital input of PLC.

The internal function of PLC uses this input for the normal operation of press brake machine. This input in combination with Oil temperature Fan input provides the following function:

This parameter defines the type of contact of oil temperature fan switch connected to the digital input of PLC.

The internal function of PLC uses this input for switching on the cooling fan of hydraulic oil.

This parameter defines the type of contact of oil filter switch connected to the digital input of PLC.

The internal function of PLC uses this input for raising the warning message in the screen. So, the operator needs to clean the filter or replace it.

This parameter defines the type of contact of auto mode I/P connected to the digital input of PLC.

This signal is from the robot controller to RA SmartCore(NC).

Signal Description: Robot in Auto mode - Switch Bend guard to Mute.

When the 'Robot Option' is selected in the PLC, the input 'Robot Auto Mode' will activate the robot functions. If Laser Safe is connected, then the Bend Guard mute is also activated.

This parameter defines the type of contact of auto mode I/P connected to the digital input of PLC.

This signal is from the robot controller to RA SmartCore(NC).

Signal Description: Robot program is started - Start button in Panel.

The 'NC Start' output signal from the NC will be ON only if 'Program Start' input from Robot controller is ON.

This parameter defines the type of contact of program abort I/P connected to the digital input of PLC.

This signal is from the robot controller to RA SmartCore(NC).

Signal Description: Robot program is aborted - Stop button in Panel.

During any bend step, if the Program Abort signal from Robot controller is set High, then all the moving axes (including RAM) are quick stopped and the 'Press OK' & 'NC Start' signals from NC is deactivated, and program aborted in Robot message is displayed.

This parameter defines the type of contact of fastdown enable I/P connected to the digital input of PLC.

This signal is from the robot controller to RA SmartCore.

Signal Description: To enable the RAM Fast Down movement in SmartCore.

When the 'Fast Down Enable' signal is ON, the RAM moves to mute point and the 'Below Mute point' signal is set to High, now the NC waits for 'Clamp move enable' signal from robot controller to move to the pinch point.

This parameter defines the type of contact of clamp move enable I/P connected to the digital input of PLC.

This signal is from the robot controller to RA SmartCore(NC).

Signal Description: To enable the RAM movement to Clamping point in SmartCore.

After RAM moves to mute point the 'Below Mute point' signal is set to High, the NC waits for the 'Clamp Move Enable' signal from the robot controller to move to the pinch point. After reaching pinch point, the “Clamping point” signal is set high.

This parameter defines the type of contact of LDP move enable I/P connected to the digital input of PLC.

This signal is from the robot controller to RA Smartcore(NC).

Signal Description: To enable the RAM movement to LDP in SmartCore.

When the 'LDP Move Enable' signal is ON, the RAM moves to LDP point and the 'LDP reached' signal is set to High, now the machine will go to dwell state and wait here until the completion of dwell time set in the current bend cycle.

This parameter defines the type of contact of UDP move enable I/P connected to the digital input of PLC.

This signal is from the robot controller to RA Smartcore(NC).
