LTI SC52.0040.0012.0000.0 Compact Servo Drive
The LTI SC52.0040.0012.0000.0 is a compact servo drive for industrial motion control. It works from a 50/60Hz supply and delivers 3.0A at 0.40kW. The output frequency range extends from 0 to 400Hz. The unit is part of the SC52 family and is designed for machine axes that need accurate positioning and stable speed regulation in limited cabinet space.
Product Overview
The SC52.0040.0012.0000.0 integrates power electronics and control circuits in a small housing. It is built for panel mounting in control cabinets and connects to compatible servo motors and feedback devices. Machine builders can use it for single axis tasks or for multi axis systems where several drives operate together. Its compact footprint helps reduce cabinet size and wiring effort.
Power Stage and Cooling
The internal power stage regulates motor current for acceleration, constant speed, and braking. Thermal monitoring protects the drive during heavy duty cycles. The 3.0A and 0.40kW ratings suit small and medium axes with moderate load requirements. Adequate clearance around the housing is necessary for heat removal. Correct fusing, grounding, and cable sizing are required for safe operation.
Control Modes
The drive supports position, speed, and torque control. Feedback from compatible encoders or resolvers is processed to close the control loop. Gain settings can be adjusted to suit load inertia and mechanical rigidity. The 0 to 400Hz output range allows flexible speed selection. Command signals can come from a machine controller, a PLC, or an analog reference.
Signal Interfaces
Digital and analog inputs and outputs allow connection to control systems, sensors, brakes, and safety circuits. Feedback cables should be shielded and routed away from motor power cables. Correct shielding practice reduces noise and improves positioning accuracy. Terminal assignments should follow the machine wiring diagram.
Diagnostics and Protection
Monitoring functions cover supply voltage, output current, temperature, and feedback condition. Fault codes and status messages help technicians locate wiring errors, overload conditions, or parameter mismatches. Protection functions reduce the risk of damage from short circuits and incorrect connections. Error history shortens troubleshooting time during service calls.
Commissioning
Setup starts with a visual check and verification of supply and motor connections. Motor data and feedback type must be entered correctly. Rotation direction, limit switches, brake output, and emergency stop functions are tested next. Loop tuning is performed with the real load attached so that the axis reaches position without overshoot or vibration.
Applications
The LTI SC52.0040.0012.0000.0 is used in packaging machinery, printing systems, handling units, small machine tools, textile machines, and special purpose automation. It suits axes where compact dimensions and accurate motion are more important than very high power output.
Maintenance and Care
Routine checks should cover cooling paths, terminal tightness, cable condition, and fault history. The drive should be kept clear of dust, moisture, and strong vibration. Parameter backups allow quick restoration after replacement. Service work should follow the machine builder and manufacturer instructions.
Summary
The LTI SC52.0040.0012.0000.0 is a compact servo drive rated 3.0A and 0.40kW with 0 to 400Hz output. Its stable power stage, flexible control modes, and diagnostic support make it a practical choice for precise motion tasks in industrial automation.
