ABB ACS850-04 Drive Modules: Hardware Manual Summary

Installation and Start-up

The installation process involves:

1. Installing mechanical accessories into the cabinet.

2. Installing auxiliary components.

3. Connecting power cables to cabling panels.

4. Mounting the drive module into the cabinet.

5. Mounting the external control unit (if applicable).

6. Connecting control cables.

7. Installing remaining cabinet parts.

A detailed installation checklist is provided to ensure all mechanical and electrical aspects are correctly installed and tightened. Before start-up, verify the installation checklist, ensure the motor and driven equipment are ready, switch on power, set up the drive control program, and validate the Safe Torque Off function.

Maintenance and Technical Data

The manual outlines routine maintenance intervals, including annual checks for fans, terminal tightness, dust, corrosion, and supply voltage quality. Capacitors require reforming if the drive has been stored for a year or more. Periodical replacement of cooling fans, DC circuit electrolytic capacitors, and certain circuit boards is recommended.

Key technical data includes:

• Ratings: Detailed input and output ratings for nominal, light-overload, and heavy-duty use across various voltage ranges.

• Derating: Guidelines for derating continuous output currents based on ambient temperature (above 40°C) and altitude (above 1000m).

• Fuses: Recommended ultrarapid (aR) fuses (IEC) and UL recognized Class T/L fuses.

• Dimensions and Weights: Physical dimensions and weights of drive modules, with and without optional components.

• Losses, Cooling Data, and Noise: Air flow, heat dissipation, and noise levels for different drive types.

• Cable Data: Terminal and lead-through data for power and control cables, including recommended cable sizes and tightening torques.

• Electrical Power Network Specification: Voltage, frequency, imbalance, and power factor requirements.

• Motor Connection Data: Supported motor types, voltage, frequency, current, and maximum recommended motor cable lengths for DTC and scalar control.

• Brake Resistor Connection Data: Ratings and connection details for brake resistors.

• DC Connection Data: Current and capacitance for common DC configurations.

• Control Unit (JCU-11) Connection Data: Specifications for power supply, relay outputs, digital inputs/outputs, analog inputs/outputs, drive-to-drive link, and Safe Torque Off connection.

• Efficiency: Approximately 98% at nominal power level.

• Degree of Protection: IP00 (UL type open), or IP20 with option +H381.

• Ambient Conditions: Environmental limits for operation, storage, and transportation, covering temperature, humidity, contamination levels, atmospheric pressure, vibration, and shock.

• Materials and Applicable Standards: Details on drive enclosure materials, recycling guidelines, and compliance with various international standards (e.g., EN 61800-5-1, EN 60204-1, UL 508C, CSA C22.2 No. 14-10, GOST R 51321-1).

• CE Marking: Confirms compliance with European Low Voltage, EMC, and Machinery Directives (for safety functions).

• EMC Compliance: Details for Category C3 and C4 drives, including provisions for meeting EMC requirements.

• UL and CSA Marking: Information on UL and CSA listings and associated checklists.

This manual serves as a critical resource for anyone involved with the ABB ACS850-04 drive modules, providing comprehensive guidance from initial planning to long-term maintenance.
