Product Overview
The ABB 1SFB536268D1007 is a PSTX Softstarter Control Board used as part of the electronic control section of ABB PSTX softstarter systems. It handles control-related processing and coordinates operating commands with the softstarter’s power-control circuitry during motor starting and stopping.
In a typical motor-control cabinet, the control board works with the PSTX softstarter power section to manage the motor-starting sequence. It processes operating commands and feedback information while coordinating the controlled application of motor power according to the configured softstarter operation.
The control board is particularly relevant in applications where reduced starting current, controlled acceleration, and controlled stopping are required. Typical installations include pumps, fans, compressors, conveyors, and other industrial motors where direct-on-line starting would produce excessive mechanical or electrical stress.
For maintenance and service work, the board can be treated as a key electronic component within the PSTX assembly. When troubleshooting a softstarter, technicians should consider the control board together with the power section, control terminals, communication interfaces, motor circuit, and configured operating parameters.

- Suitable for industrial motor-control applications
- Interfaces with associated PSTX control and monitoring functions
- Applicable to replacement and service of compatible PSTX softstarter assemblies
Working Principle
The control board receives operating commands and relevant feedback from the softstarter control system. It processes these signals and coordinates the required operation of the PSTX power section.
During motor starting, the board controls the softstarter sequence so that the power section applies the required motor voltage progressively rather than switching the motor directly to full line voltage. The resulting controlled acceleration helps reduce starting stress on the motor and driven equipment.
During stopping, the control board manages the configured stopping sequence and communicates the required control signals to the power section.
Start / Stop Command → PSTX Control Board → Power-Control Section → Motor
Additional feedback and status information can be returned to the control system for monitoring, diagnostics, and protection functions. The exact behavior depends on the PSTX configuration and connected control architecture.
Role in an ABB PSTX Softstarter Control Architecture
The 1SFB536268D1007 forms part of the electronic control layer inside the PSTX softstarter. It works between external control commands and the power-control circuitry that directly regulates motor power.
PLC / HMI / Operator Command → PSTX Control Board → PSTX Power Section → Motor
| System Element | Function |
|---|---|
| PLC / Controller | Sends operating commands and receives status |
| HMI / Operator Interface | Provides local monitoring and command entry |
| PSTX Control Board | Processes commands and coordinates softstarter operation |
| PSTX Power Section | Controls electrical power applied to the motor |
| Motor Protection | Provides protection for the motor circuit |
| Motor | Performs the mechanical work |
| Driven Equipment | Pump, fan, compressor, conveyor, or other load |
The control board therefore works as part of a larger motor-control chain rather than operating as an independent motor controller.
Industrial Applications
| Application | Typical Use |
|---|---|
| Pump Systems | Controlled starting and stopping of pumps |
| HVAC Equipment | Soft starting of fans and air-handling motors |
| Compressors | Reduced starting stress on compressor motors |
| Conveyors | Controlled acceleration of conveyor drives |
| Water Treatment | Motor control for pumps and auxiliary equipment |
| Material Handling | Controlled starting of industrial machinery |
| Process Machinery | Motor starting in automated production systems |
| Industrial Machinery | General-purpose motor starting and stopping |
Installation and Maintenance
- Confirm that the 1SFB536268D1007 is the correct replacement for the installed PSTX softstarter assembly.
- Isolate the softstarter and follow the applicable electrical safety procedures before accessing the control board.
- Record the existing board connections and configuration before removal.
- Check connectors, terminals, and board interfaces for contamination or physical damage.
- Handle the control board using appropriate electrostatic-discharge precautions.
- Verify that associated PSTX components are compatible with the replacement board.
- Install the board carefully and ensure all connectors are fully seated.
- Check control wiring against the approved machine or panel schematic.
- Restore control power and verify that the PSTX system initializes correctly.
- Check displayed status, alarms, and control functions after replacement.
- Test motor starting and stopping under controlled operating conditions.
- Verify communication, protection functions, and external control commands before returning the equipment to normal operation.

Technical FAQs
What is the function of the ABB 1SFB536268D1007 control board?
It serves as a control-board component within the PSTX softstarter, processing operating commands and coordinating the softstarter’s control functions with the associated power section.
What should be checked if a PSTX softstarter powers up but does not start the motor?
Check the external start command, control wiring, configured permissives, active alarms, motor circuit, and the communication between the control section and power section. The control board should not be identified as the fault source until these associated conditions have been verified.
Can the control board be replaced without checking the rest of the PSTX assembly?
No. The replacement should be checked against the complete softstarter assembly and its configuration. Connectors, control wiring, power section, communication interfaces, and application parameters should all be verified during replacement.
What tests should be performed after replacing the control board?
Verify initialization first, then check alarms and status indications, external control commands, communication functions, and configured protection functions. A controlled motor start and stop test should be performed before returning the equipment to normal service.
