Smooth Operation: Vibration-free performance in belt mechanisms.
Easy Handling: Basic settings via front panel switches and potentiometers.
Monitoring and Setting: Parameter changes and system monitoring via OPX-2A control module or MEXE02 software.
Control Modes: Four control modes with extended functions through additional modules.
High Speed and Response: Maximum speed of 5500 r/min and settling time of 60 to 70 ms.
Damping Control: Load resonance eliminated through potentiometer adjustments.
Absolute System: Optional battery for storing encoder positions.
Speed and Torque Control: Enhanced torque accuracy and reduced cogging torque.
Tension Control: Simplified tension control for applications like film winding.
IP65 Protection: Dust and water-resistant for harsh environments.
Simple Connections: Includes 3 m cables, with longer options available.

System Configuration
Describes a typical single-axis system configuration using the SG8030J controller in position control mode, with various accessories and modules for extended functionality.

Product Line
Includes standard and geared types, with options for electromagnetic brakes. Models vary by power supply input and output power, ranging from 50 W to 750 W.

Speed-Torque Characteristics
Graphs illustrate speed-torque characteristics for different models, showing maximum and permissible torque.

Additional Notes
Mentions need for a heat sink for continuous operation and potential requirement for a regeneration unit. UL/CSA standards are pending.

Protection Features
Includes multiple protection mechanisms to ensure safe operation, triggering alarms when necessary.

Input/Output Signals
Specifies various input and output signals with specific conditions for external use.

Control Modes

Position Control Mode: Pulse input modes with a maximum frequency of 500 kHz, resolution from 1000 to 100000 P/R.
Speed Control Mode: Speed settings from 10 to 5500 r/min, with regulation within ±0.05%.
Torque Control Mode: Torque control from 0 to 300% of rated torque.
Tension Control Mode: Modes for maintaining constant tension, with automatic calculations for winding diameter and load inertia.

General Specifications
Motor driver has a thermal class of 130 (B) and insulation resistance of 100 MΩ, operating within 0 to +50˚C and up to 85% humidity. Degree of protection is IP65.

Specifications and Wiring Guidelines
Specifies wire use and connection guidelines to maintain performance and prevent interference.

Analog I/O Connection
Requires an accessory set, with specific impedance and voltage range details.

Motor and Driver Combinations
Lists combinations for different power supply inputs and output powers.

Extended Functions
Parameters such as torque limiting and vibration suppression can be set using additional modules or software.

Technical Support
Contact information for technical support is provided.

Additional Features
Includes acceleration/deceleration correction filters and friction torque correction for performance optimization.

Servo Motors ◇ Speed Control This servo unit can operate in 4 control modes. Also, with the separately sold control module (OPX-2A) or data setting software (MEXE02), the functions of each control mode can be extended. The reduction of motor cogging torque and the use of a highresolution encoder have substantially reduced variation in rotation in the low-speed range (the flutter characteristic), resulting in smooth operation even at low speeds. 8 ●High Speed and High Response High-speed positioning can be performed utilizing the high-speed and high-response characteristics. 5500 r/min Factory...
