Key Features
Technical capabilities designed for precision and reliability.
- High-current output up to 5.5A – drives high-thrust bi-polar stepper motors for large LHS and RLA actuators that exceed the 2A driver capacity
- Separate power supply input – M12 4-pin S-coded connector accepts 24 VDC (MC QD 1181) or 24–48 VDC (MC QD 1180/1260) from a dedicated power supply for maximum motor performance
- High-precision 256 microstep driver – constant current driver with 256 microsteps per full step for smooth, vibration-free motion even under heavy loads
- RS485 communication from SCU5 – M8 4-pin twisted pair motor communication cable; 24 VDC on the cable powers the servo center (not the drive logic or the motors)
- Automatic parameter initialization – driver parameters stored in SCU5 controller memory are loaded on every power-up
- Ramp profile generation – generates acceleration/deceleration ramp profiles based on speed and acceleration settings for controlled actuator positioning
- Electronic stroke limits – configurable step counts for electronic stroke limits protect the actuator from over-travel
- Servo center input – M8 6-pin connector supports a 24V NPN inductive proximity sensor for home/servo center positioning
- Limit switch inputs – two normally-closed limit switch inputs to restrict actuator travel; can be tied together for a single enable/disable switch via the same M8 6-pin connector
- T-coded actuator output – M12 4-pin T-coded female connector for higher-current actuator cables (distinguished from standard M12 to prevent cross-connection)
- Aluminum wall-mounting enclosure – mounts in a machine cabinet or on the machine frame close to the actuator
Key Benefits
Measurable business value and operational improvements.
- Drive the heaviest actuators in the lineup – 5.5A output powers LHS-030 and RLA series actuators delivering 300–1,500 lbf of thrust for large unwind/rewind stands
- Choose the right voltage for your application – 24 VDC models (MC QD 1181) for moderate loads, 48 VDC models (MC QD 1180/1260) for maximum speed and thrust
- Stop losing precision under heavy loads – 256 microstep resolution maintains smooth, vibration-free positioning even at maximum thrust
- Prevent actuator over-travel damage – electronic stroke limits and hardware limit switch inputs provide dual-layer protection for expensive large-stroke actuators
- Same communication interface as the 2A driver – identical RS485 cable and SCU5 setup; operators and technicians need to learn only one system
