LTi Drives Servo Controller SO84.004.0002.0100.2

The LTi Drives Servo Controller SO84.004.0002.0100.2 is a servo drive designed for precise motion control in industrial automation. It is identified by the part number SO84.004.0002.0100.2. The unit is rated for 4.0 A output, 0 to 400 V, three phase, and 0 to 400 Hz. It is used to control servo motors in machines that require accurate speed, torque, and position regulation.

Servo controllers are essential in modern automation because they convert control signals into the power needed to move a motor. The SO84.004.0002.0100.2 performs this task with a compact design and robust construction.

Product Overview

The SO84.004.0002.0100.2 is a compact drive module for control cabinet mounting. It accepts a three phase supply and provides a controlled output to the motor. The output frequency range of 0 to 400 Hz allows it to drive motors at various speeds. The drive communicates with a higher level controller and receives command signals for speed or torque. Feedback from the motor is processed internally to maintain accurate regulation.

The model designation SO84 identifies the series, while the remaining numbers indicate specific configuration and power ratings. The drive is designed for smooth integration into new machines and for upgrades of existing systems.

Key Features

• Servo controller for industrial motion control

• 4.0 A output current

• 0 to 400 V three phase supply

• 0 to 400 Hz output frequency

• Compact design for control cabinet installation

• Closed loop control for speed and torque

• Fast response to load changes

• Integrated protection functions

Technical Description

The drive operates from a three phase supply of 0 to 400 V and provides a controlled output to the motor. The output stage is rated for 4.0 A continuous current, with short term peak capability for acceleration. The output frequency range of 0 to 400 Hz allows flexible speed control. The control electronics process feedback signals from an encoder or resolver to maintain accurate position and speed.

The drive is protected against overvoltage, undervoltage, overcurrent, and overtemperature conditions. Faults are reported to the controller so that the machine can react appropriately.

Control and Performance

The SO84.004.0002.0100.2 uses closed loop regulation to keep the motor on the commanded trajectory. The current loop responds quickly to changes in load, which is important in applications that start and stop frequently or that process materials with varying resistance. Speed and position loops are tuned through the engineering software to match the connected motor and mechanical system.

Parameters such as acceleration, deceleration, current limits, and speed limits are stored in the drive or in the machine project. Once configured, the drive operates autonomously while remaining under the supervision of the main controller.

Applications

The drive is suitable for a wide range of motion tasks. In packaging machinery, it can control film feed, sealing, and cutting axes. In assembly equipment, it positions tools and fixtures. In material handling, it drives lifts, transfer units, and shuttles. In textile and printing systems, it maintains the constant speed and tension that product quality depends on.

Because the drive is compact, it fits well into machines where cabinet space is limited. It can be used in new designs or as a replacement for existing drives in legacy systems.

System Integration

Integration begins with mounting the drive and connecting the supply, motor, and feedback lines. The controller recognizes the drive and makes its parameters available in the programming environment. After basic settings are entered, the axis can be tested in manual mode and then linked to the machine sequence.

Shielding and cable routing follow the installation guidelines. Motor cables should be kept short where possible, and signal cables should be separated from power lines. These measures reduce electrical interference and support stable operation.

Installation Notes

Correct installation supports reliable operation. The drive should be mounted vertically with enough clearance for air circulation. The ambient temperature inside the cabinet should remain within the specified range. Power and signal cables should be routed according to the system guidelines. Grounding must be done properly to ensure safety and electromagnetic compatibility.

Maintenance and Diagnostics

The drive has no wearing mechanical parts in its control section, so maintenance is mainly preventive. Terminal connections should be checked periodically. Cooling paths should be kept clear of dust. If a fault occurs, the diagnostic data helps determine whether the cause is in the drive, the motor, or the wiring.
