Description
Product Overview and Description
The ABB DSDP140B 57160001-ACX is a high-performance servo drive module from ABB’s comprehensive motion control portfolio, specifically part of the MicroFlex e190 series. This module functions as a digital servo drive/amplifier, designed to provide precise speed, torque, and position control for synchronous (permanent magnet) servo motors. The primary role of the ABB DSDP140B is to convert control commands from a superior motion controller (like an ABB PLC or independent motion CPU) into the high-power, conditioned three-phase output required to drive a servo motor with exceptional dynamic response and accuracy. The suffix “57160001-ACX” denotes a specific hardware configuration and revision, including options for specific feedback systems, braking resistors, and communication interfaces. The integration of the ABB DSDP140B into an automation system is central to achieving high-speed, coordinated motion in applications ranging from packaging to robotics, where precise movement is critical.

Its robust design ensures reliable operation in industrial environments with electrical noise. The availability of a wide range of fieldbus options provides flexibility for integration into virtually any machine control architecture. The integrated safety function (STO) helps simplify safety system design and comply with relevant standards. The comprehensive suite of protective features and diagnostics enhances system reliability and simplifies troubleshooting.
Application Scenarios and Use Cases
This servo drive is engineered for high-performance motion control applications. It is commonly used in:
-
Packaging Machinery: For controlling cut-to-length axes, flying saws, and precision filling heads.
-
Printing and Converting: To drive printing cylinders and web tension control systems with exact registration.
-
Machine Tools: For controlling feed axes, spindle orientation, and tool changers.
-
Material Handling Robots: For articulated arm joints in pick-and-place and assembly robots.
-
Textile Machinery: For controlling winders, spindles, and precise feed systems.
In these applications, the ABB DSDP140B receives position or velocity commands from a central motion controller and delivers the precise electrical power needed to execute complex motion profiles with minimal error.
Comparison with Competing Products
The ABB DSDP140B competes directly with other digital servo drives in its power class from manufacturers such as Siemens (SINAMICS S210/S120), Rockwell Automation (Kinetix 5700), Bosch Rexroth (IndraDrive), and Yaskawa (Sigma-7). Compared to standard variable frequency drives (VFDs), it offers far superior performance for positioning and dynamic speed control. Within the servo drive market, ABB’s MicroFlex series is recognized for its strong integration with ABB’s automation ecosystem (AC500 PLCs, etc.) and its robust design. Key differentiators often include the specific tuning software, diagnostic capabilities, and the breadth of supported feedback and communication options. The 57160001-ACX configuration ensures compatibility with specific motors and feedback types, which is a critical selection factor.
Selection Guidelines and Important Notes
Selection Advice:
-
Motor-Drive Matching: This is paramount. The ABB DSDP140B must be matched with a compatible ABB servo motor. Verify that the drive’s current and voltage ratings meet or exceed the motor’s requirements.
-
Feedback Compatibility: The specific configuration 57160001-ACX must support the feedback device (encoder/resolver type) on the chosen servo motor.
-
System Architecture: Decide on the control architecture. The drive typically requires a separate motion controller (e.g., ABB NCMC card in a PLC) or can sometimes operate in standalone mode with a fieldbus setpoint. Select the appropriate communication option module.
-
Power and Braking: Ensure the electrical supply matches the drive’s input requirements. For applications with frequent deceleration, size an external braking resistor appropriately if the internal dynamic brake is insufficient.
-
Software Tools: Ensure access to ABB’s DriveWare software for commissioning, parameterization, and diagnostics.
Important Precautions:
-
High Voltage Hazard: The drive operates with lethal high voltages. Installation and maintenance must be performed by qualified personnel with all power disconnected and locked out.
-
Correct Grounding: Proper protective earth (PE) grounding of the drive, motor, and cabinet is essential for safety and EMC performance.
-
EMC Compliance: Use shielded motor and feedback cables. Terminate shields correctly (usually at the drive end) to minimize electromagnetic interference.
-
Thermal Management: Install the drive in a well-ventilated enclosure respecting clearances. Overheating is a primary cause of drive failure.
-
Parameter Backup: Always save a complete set of drive parameters after commissioning. This file is crucial for disaster recovery.
-
Safe Torque Off (STO): If using the integrated STO, wire and validate this safety circuit according to applicable machinery safety standards (e.g., ISO 13849-1).
