General

This parameter selects the type of valve used in the machine.

Depending on the type of the valve selected in this parameter, corresponding valve parameter table is loaded into the controller.

The valve control amplifier controls the hydraulic valve that regulates the flow and pressure of hydraulic fluid to the cylinders that drive the press brake’s ram. The amplifier helps manage the precise movement of the press brake’s ram, which ensures smooth and accurate bending operations.

The Valve control amplifier regulates the ram movement.

It is used to control the ram movement.

The option to select External amplifier type will only be available when the Valve control amplifier is set to External (Y-Axis Parameters > General > Valve control amplifier).

External amplifier type defines the type of the valve control amplifier.

This parameter defines the type of machine in which the controller is deployed.

Depending on the type of the machine, the internal PLC functions are activated automatically. The controller supports the following type of machines:

This parameter defines the pump off time during idle running of the induction motor.

If there is no operation is carried out during this specified time, the pump will automatically be turned OFF. If the operator forgets to hit the emergency stop before leaving, this function will be very useful to save the energy.

This function is not implemented in the internal PLC, since the logic of Pump ON & OFF varies depending on OEM’s.

But still this parameter is available in the PLC as 'YParam.General.PumpIdleRunTime' for the OEMs to write their own logic.

This parameter defines the minimum position the RAM can be moved to.

This value is used as a negative software limit. When the start button on the control is pressed the control checks all Y-axis parameters, which are programmed or computed. If a programmed or computed Y-axis value is smaller than Y-min, the value is limited at the Y-min value and an error message appears on the screen.

'Y-Axis - Target < Negative software Limit'

This parameter defines the maximum position the RAM can be moved to.

This value is used as a positive software limit. When the start button on the control is pressed the control checks all Y-axis parameters, which are programmed or computed. If a programmed or computed Y-axis value is greater than Y-max, the value is limited at the Y-max value and an error message appears on the screen.

'Y-Axis - Target > Positive software Limit'

This parameter defines the count direction of Y-axis linear scales with respect to the bottom of the table.

If this parameter is configured as 'UP', then the Y-axis position value is increased when the beam approaches the bottom of the table (i.e.,) closing. If programmed 'down', then the Y-axis position value is decreased when the beam closes.

This parameter defines the maximum allowed difference between the left beam position (Y1) and the right beam position (Y2).

This value is the maximum position difference allowed between Y1 and Y2 axis and if the difference exceeds beyond this value the controller will stop and an error message appears on the screen.

'RAM Synchronization error'

This parameter is not validated.

NA

This parameter defines the maximum allowed braking time of the ram.

The stopping of RAM during emergency condition or foot pedal released etc., can be programmed using this parameter.

This parameter is used to change the valve offset for Y1 axis.

NA

This parameter is used to change the valve offset for Y2 axis.

This parameter defines the maximum allowed difference between the tracking error of Y1 and Y2.

Tracking error is the difference between the computed cycle and the measured cycle. This parameter serves to set the maximum allowed difference between the tracking errors of Y1 and Y2. If this difference is exceeded, a warning is issued on the screen and the PLC flag 'YParam.LagError_Op' is set. This PLC flag can be used in the PLC program, for instance to stop the machine.

If this parameter is programmed to zero, this mechanism is not used.

This parameter defines the guard, the maximum difference between Y1 and Y2.

The difference between the linear scale of Y1 & Y2 readings are monitored, if the difference becomes larger than the programmed value the corresponding PLC 'flag YParam.Y1Y2Diff_Op' is set. This flag can be used in the PLC program, for instance to stop the machine.

If this parameter is programmed to zero, this monitoring is not done.

This parameter is not validated.

NA
