Product catalog summary

Introduction to Junma Servo System
The Junma Servo System, incorporating the SJME Servo Motor and SJDE SERVOPACK, is engineered for high-performance applications with an emphasis on simplicity in setup and operation. It employs advanced servo technology to achieve high-speed, high-torque, and high-precision performance without requiring parameter settings or gain adjustments.

Key Features

Plug and play design with pre-matched motor and amplifier sets.
Automatic system parameter setup and load inertia calculation.
Dynamic tuning gains and vibration suppression capabilities.
Available input voltage options of 120 or 240 VAC (single phase).
Feedback resolution of 65,536 pulses per revolution.
Control input via pulse and direction signals.
Advanced functionalities such as adaptive tuning, jogging, homing, electronic gearing, torque limiting, and position complete output.

Specifications

Torque output at speeds up to 4500 RPM.
Rated output power from 100 W to 750 W, depending on the model.
Rated torque ranging from 0.318 Nm to 2.39 Nm.
Instantaneous peak torque up to 7.16 Nm.
Rated speed of 3000 RPM and maximum speed of 4500 RPM for 200V models.
Enclosure rated IP55, excluding shaft opening and connectors.

Installation and Setup

Simple installation with provided cables for power supply, signal lines, and motor connection.
No need for parameter settings or gain adjustments during setup.
Setup completion allows the motor to operate with controller reference, achieving required torque even at high speeds.

Performance and Safety

Defined continuous and intermittent duty zones for operation.
Protection against speed errors, overload, encoder errors, voltage errors, and over currents.
Built-in dynamic brake and optional regenerative processing for energy management.

Compliance and Standards

Conforms to international standards for safety and performance.
Protection class IP1X and vibration resistance of 4.9 m/s².

Accessories and Connectivity

Various cable lengths and connector kits available for customization.
Regenerative units and communication boards for enhanced functionality.

Power Supply and Safety Features
The document details the power supply components for I/O signals, including switches and relays. SW1 is the power-off switch, and SW2 is the power-on switch. MC1 is a magnetic contactor, and Ry1 is a relay for holding the brake. The ground fault protection circuit is designed to protect against faults within motor windings during operation but may not protect against low-resistance ground faults in the main circuit cable or if the power supply is turned on during a fault. It is recommended to install a ground fault interrupter or a molded-case circuit breaker with a ground fault interrupter for enhanced safety.

Component Specifications
The document lists components and their manufacturers: Surge absorber by Okaya Electric Industries (CRE-50500), Flywheel diode by Toshiba Corp. (1NH42), Relay for holding brake by Omron Corp. (MY series), and Varistor by Nippon Chemi-Con Corp. (TNR7V121K).

Connection Diagram and Model Designations
The connection diagram includes the SJDE SERVOPACK and Junma Series Servo Motor. Model designations for servo motors and amplifiers are provided, detailing specifications such as capacity, voltage, brake specifications, interface, feedback, and shaft end specifications. The Junma Series Servo Motor operates at 3,000 to 4,500 rpm with capacities ranging from 100 to 750 W.
