REXRTOH DIAX04 Second Generation Driver Controller Application Guide

Integrated Control Card (CLC-D02.3M): Used for SYNAX multi axis synchronization applications.

Configure identification and type code

Each drive is equipped with a configuration type label, which records the type codes of the basic unit, software module, and each slot module for easy maintenance and spare parts identification. HDD02.2-W040N-HD32 is a dual axis fixed configuration type, integrating SERCOS interface and second encoder interface.

Electrical connection and signal interface

The drive controller provides rich interfaces, supporting the connection of power supply, communication, feedback, and control signals:

X1: Integrated bus connection, used for communication and power supply with adjacent units, with a maximum length of 1 meter;

X2: Serial interface (RS-232/RS-485), used for parameter setting and diagnosis;

X3: Analog output (± 10V), ready signal and start lock;

X4: Motor feedback interface (encoder 1), supporting standard encoders such as HSF/RSF;

X5: Intermediate circuit, motor and power connection, including DC bus, motor three-phase line and grounding;

X6: Maintain brake and motor temperature monitoring;

X7.1/X7.2: Second encoder interface (1Vpp sine signal), used for high-precision position detection;

X10/X11: ERCOS fiber optic interface, supports 2M/4M baud rates, complies with IEC/EN 61491 standard;

X12.1/X12.2: External digital input, used for reference switches, limit switches, emergency stop signals, etc.

Wiring suggestions

Signal lines and power lines should be arranged separately, with a minimum spacing of 100mm or isolated using metal wire trays;

The maximum length of motor cable and feedback cable is 75 meters (ambient temperature ≤ 40 ° C);

The shielding layer should be grounded at the controller end, using original cables or shielded cables that comply with specifications.

Control cabinet design and heat dissipation management

1. Mechanical installation

Use SUP-M01-HD to install the guide rail vertically, with the motor interface facing downwards;

The driver should be arranged close to the power unit, and when the total power is greater than 36kW, it should be evenly distributed on both sides;

The guide rail needs to be fixed every two slots with M5 screws and ensure good electrical contact with the mounting plate.

2. Heat dissipation calculation

Driver power loss includes control unit loss, configuration module loss, and power segment loss. The manual provides loss curves for various models of drivers at different currents. Users can calculate the total loss based on the actual operating current and design corresponding heat dissipation schemes. For example, the total loss of a four axis system may be close to 2kW, which needs to be naturally dissipated through the control cabinet or discharged through the installation of a cooling system.

3. Use of cooling system

The set temperature of the cooling system shall not be lower than 40 ° C to prevent condensation inside the cabinet;

The air outlet should not be aligned with electronic devices to prevent condensation from falling;

After shutdown, the cooling system should continue to operate until the temperature inside and outside the cabinet is balanced.

4. EMC protection measures

The motor cable must be shielded and grounded at the controller end;

Install interference suppression filters at the power supply inlet end;

Inductive loads (contactors, relays) should use RC modules or freewheeling diodes to suppress interference.

Debugging, diagnosis, and maintenance

1. Debugging and parameter settings

Before the first use of the drive, it needs to be parameterized through software (such as DriveTop), which can be connected to a PC through RS-232/RS-485 interface or SERCOS interface. The software module HSM supports parameter storage and migration, and can quickly restore configuration when replacing the drive.

2. Diagnostic function

The driver outputs error messages through the front panel status indicator H1 and SERCOS interface;

Analog diagnostic output AK1/AK2 can output internal signals (such as current and speed) for oscilloscope monitoring;

The ready signal Bb can be used for system level status monitoring.

3. Service and Support

Rexroth Indramat provides a global service network, including:

Technical Support Hotline (Germany Headquarters:+49 9352 40-4894);

7 × 24-hour service hotline (mobile phone);

Sales and service centers in various regions (covering Europe, America, Asia, etc.).

Maintenance and repair should be carried out by certified personnel, and re debugging is required after replacing the unit. The driver has undergone high voltage and insulation testing in accordance with DIN VDE 0160.

Typical application scenarios

The DIAX04 driver is suitable for the following high dynamic, multi axis cooperative control systems:

CNC machine tools: spindle drive, feed axis control;

Packaging machinery: positioning, sealing, labeling;

Printing equipment: drum synchronization, tension control;

Robots: joint drive, trajectory planning;

Handling system: positioning handling, synchronous conveying.
