Optimal Operation Guide for DELEM DA53T/DA58T Z-axis Controller

Improper configuration of the DELEM DA53T/DA58T Z-axis Controller can severely compromise the operational efficiency of press brakes. This comprehensive guide details the correct setup and operational methods of the Z-axis Controller, aiming to help operators achieve smooth and high-precision press brake operation by mastering its core functions and configuration processes.

The DELEM DA53T/DA58T Z-axis Controller is a dedicated control component developed for the DELEM DA53T/DA58T CNC system. It is integrated with the Schneider Easy Harmony touch screen and Schneider TM200 PLC, an integration that upgrades the DA53T/DA58T system to support 6+1 axis control, greatly enhancing the system's operational flexibility and precision. The adopted touch screen model is HMIET6401, featuring a 7-inch display with a resolution of 800×480 pixels and a 16-million-color TFT LCD screen for clear and intuitive operation.

1. Basic Operation Overview of the Z-axis Controller

For the DELEM DA5XT series systems (including DA53T/DA58T), the Z-axis can be controlled via both single-step and multi-step programming modes—just like the X and R axes, the Z-axis control mode can be freely customized on the DA5XT system.

The core operational steps for Z-axis programming are as follows:

1. Based on the actual sheet metal length and punch position, input the accurate Z-axis programming coordinates on the JUGAO touch screen;

2. For each programming step on the DA5XT system, assign a unique Z-axis ID (the ID value is in binary format, with a configurable range of 0000 to 1111).

Both single-step and multi-step Z-axis operation modes support arbitrary setting of Z-axis ID values within the 0000-1111 binary range, and the system provides visual operation examples for both modes to facilitate operator understanding and operation.

2. Detailed Operation on the JUGAO Touch Screen

The JUGAO touch screen is the core human-machine interface for Z-axis manual and automatic operation, with clear and differentiated operation logic for different working modes, as well as dedicated handling methods for abnormal situations and daily calibration.

2.1 Manual Operation Method

Manual operation of the Z-axis is only available when the specified manual operation icon is displayed on the touch screen; if the icon is not shown, manual control is disabled.

• Press the forward control key to drive Z1 or Z2 to move in the direction of position value increase (the Y1 side corresponds to the minimum Z-axis value position, and the Y2 side corresponds to the maximum Z-axis value position);

• Press the reverse control key to drive Z1 or Z2 to move in the direction of position value decrease, and the movement stops immediately when the key is released;

• Z1 and Z2 switching: Press the axis selection key, and Z2 will display in blue, indicating that Z2 is in the manually operable state; press the key again, Z2 reverts to black, and the manual operation right switches back to Z1.

2.2 Automatic Operation Method

Automatic operation of the Z-axis is triggered by the dedicated automatic start key on the JUGAO touch screen, with a precondition check for the equipment state:

• If the oil pump of the press brake is not started, the screen will prompt the operator to start the oil pump first;

• If the oil pump is in the normal working state, pressing the automatic start key will drive the Z-axis to move to the preset position corresponding to the Id0000;

• Press the dedicated stop key on the screen at any time to immediately stop the Z-axis automatic movement.

2.3 Abnormal Handling for Collision Accidents

In the event of a collision between the Z1 and Z2 stop fingers during operation, handle the abnormality in the following order:

1. First check whether the Z-axis drive module has an alarm signal; if an alarm is triggered, power off the drive module and restart it to reset the alarm;

2. Perform the "teaching" calibration operation for both Z1 and Z2 axes;

3. Input the actual current accurate position values of Z1 and Z2 on the touch screen, and after confirmation, the system can resume normal subsequent operations.

2.4 Key Requirements for Z-axis Teaching (Calibration) Operation

The correct Z-axis teaching (calibration) is the fundamental prerequisite for the normal and accurate operation of the entire Z-axis Controller, and this operation must be performed in the following scenarios:

1. The first trial run and commissioning of a new press brake equipped with the DA53T/DA58T Z-axis Controller;

2. Any accidental collision of the Z-axis stop fingers or other abnormal mechanical impacts on the Z-axis.

It is important to note that the Z-axis Controller has a power-off memory function: the calibrated Z-axis position parameters will be automatically stored by the system. After the equipment is powered off and restarted, the operator does not need to re-perform the teaching (calibration) operation, and the system can directly call the stored parameters for operation.
