Kollmorgen SERVOSTAR 600 (S600) series digital servo drive

Automatic restart risk: If the parameter AENA is set to 1, the drive may automatically restart after power is restored, and clear warning signs must be set on the machine to ensure that personnel cannot power on when in a hazardous area.

Surface high temperature: During operation, the surface temperature of the radiator may exceed 80 ° C, and it needs to be cooled to below 40 ° C before contact.

Functional safety limitation: The control of the built-in brake in the motor cannot be used to achieve functional safety. For vertical suspended loads, an additional mechanical braking device controlled by the electromechanical circuit must be equipped.

Leakage current treatment: Due to high-frequency switching, the driver will generate leakage current. The calculation formula is I2 leak=n × 20mA+L × 1mA/m (at 8kHz). If the calculated value exceeds 3.5mA, double PE wire or grounding wire with a cross-sectional area greater than 10mm ² should be used.

2.3 Compliance with global certification standards

The SERVOSTAR 600 series has obtained UL 508C, UL 840 (file number E217428), and cUL certifications, meeting the requirements of the North American market. At the same time, it declares compliance with the EC EMC Directive (2014/30/EC) and the Low Voltage Directive (2014/35/EC), meeting the immunity requirements for industrial environments (Class 2) and the emission requirements for Class C3 products. However, as a component, the responsibility for the entire machine to comply with relevant directives (such as the Machinery Directive 2006/42/EC) after its final integration into the machine lies with the machine manufacturer.

Chapter 3: Installation, Setting up, and Operational Practice

3.1 Key points of mechanical and electrical installation

Mechanical installation requires vertical placement, ensuring good forced ventilation inside the cabinet and an ambient temperature not exceeding 45 ° C (under rated conditions). Electrical installation is the key to stable system operation:

Cable separation: Power cables and control cables should be laid separately, with a recommended distance of at least 200mm to improve anti-interference ability.

Shielding and grounding: All shielding layers must be grounded with a large area and low impedance at both ends. When the motor power cable exceeds 25 meters, a motor reactor (3YL) needs to be installed near the amplifier.

Key signal connection: The BTB/RTO (ready) contacts must be connected in series to the emergency stop circuit of the system. The simulated ground (AGND) must be connected to the control system ground (CNC-GND).

3.2 Software Debugging and Quick Startup

Kormorgen provides DRIVE. EXE setup software, which connects the PC and driver through an RS232 interface (X6), providing an intuitive interface for parameter configuration, monitoring, and diagnosis. Its' Quick Start Guide 'summarizes the basic debugging process:

Preparation and wiring: Complete the minimum system wiring (power supply, motor, feedback, enable).

Connection and Communication: Establish an online connection by selecting the correct serial port through software.

Basic settings: Configure basic parameters (such as grid voltage) in the software, select motor models (call parameters from the built-in database), and match feedback types in sequence.

Save and restart: After configuring parameters, they need to be saved to EEPROM and perform a cold start to make the parameters effective.

Testing and Monitoring: Use the "Jog" function of the software to test the motor operation, and use the "Oscilloscope" and "Monitor" functions to observe real-time data such as speed, current, and position.

3.3 Fault diagnosis and status monitoring

The front of the drive is equipped with a 3-character LED display screen, which can display status codes, error (E.xx), and warning (n.xx) information. For example, F02 represents overvoltage on the DC bus, F05 represents undervoltage, and n05 represents phase loss in the power grid. The 'Status' screen in the software provides more detailed diagnostic information. The manual and software online help provide rich troubleshooting guidelines, such as checking the enable signal, phase sequence, and brake when the motor does not rotate; Motor oscillation may be caused by high speed loop gain or feedback cable shielding issues.

Chapter 4: Advanced Features, Options, and System Expansion

4.1 Optional Expansion Card Ecosystem

The option slots of SERVOSTAR 600 bring great scalability to its network communication capabilities, and users can choose based on the upper layer architecture:

Fieldbus cards: PROFIBUS-DP, DeviceNet, EtherCAT, SynqNet, SERCOS interface cards, enabling deep integration with different PLCs and control systems.

I/O expansion card (- I/O-14/08-): Provides 14 digital inputs and 8 digital outputs, specifically designed to trigger and execute motion tasks stored within the drive, suitable for independent or semi independent positioning control.

Interface Separation Module (-2CAN -): Separate the RS232 and CAN signals shared on the X6 interface into separate Sub-D connectors for easy wiring and use of standard cables.
