Actuator 3Nm shaft 10mm key SQM45.291B9 PLC Module

SQM45.291B9 – Actuator, 3Nm, 90°/10s, CAN bus, shaft 10mm+key, holding torque 1.5Nm

SQM45.291B9 is an industrial-grade actuator (also often called a servo motor) launched by Siemens. It is mostly used for precise control of valves and dampers in industrial scenarios such as combustion systems.

SQM45.291B9 adopts a sturdy aluminum alloy casing with a protection level of IP67, which can withstand harsh environmental influences such as dust and water, and can adapt to harsh working conditions in industrial sites. In some scenarios, it also supports 60 Hz power supply, in which case the running time can be shortened to 8 seconds.

FAQ:

How does SQM45.291B9 work?

1. After receiving the LMV5 control unit instructions via the CAN bus (simultaneous bus power supply), the functions are first assigned via the addressing keys.
2. The built-in stepper motor drives the gear set and outputs torque through the keyed shaft to drive the valve/damper to rotate accurately.
3. Position signals are collected in real time and fed back to form closed-loop control, and the status is displayed with visual indicators.
4. Maintain a safe position in case of failure and support manual emergency operation.

How to install SQM45.291B9 ?

1. Preparation: Check the product accessories, choose a flat mounting surface, stay away from strong magnetic fields, and follow electrical safety standards.
2. Mechanical fixation: Front fixation with bolts, the shaft and the adjustment mechanism are connected without gaps, and the tightening torque is controlled.
3. Wiring and addressing: The CAN bus is connected in series to the LMV5 control unit, and the terminal resistor is enabled at the end point; use the addressing keys to assign functions, and return the cover after completion.
4. Commissioning: Check wiring and positioning actions, test fail-safe functions and manual emergency operation.
