2450 Modular Performance DC Drive

2450 Modular Performance DC Drive

The 2450 is an all-digital pulse-width-modulated (PWM) DC drive. Its revolutionary technology and modular design make it the optimum drive where superior performance, flexibility, and ease of operation are desired.

General

• All-digital control for zero drift and repeatable motor operation
• 24-bit DSP computational power for fast, dynamic response
• High-switching-frequency IGBT devices for quiet operation
• Digital current-loop regulator for fast response
• Servo loop operation for precise velocity, position, or torque control
• Full torque from zero to rated speed
• Field weakening at constant horsepower up to four times base speed

Ease of Installation, Setup, and Maintenance

• Complete, self-contained package requires few option boards
• Identical control boards across full power range reduces spare parts
• Snap-in signal connections for ease of wiring
• Automated setup feature requires no chart recorders or meters
• Software calibration and adjustment eliminates tuning components
• Software input and output scaling eliminates potentiometers
• Automated hardware configuration check

Ease of Use

• Full keypad for easy entry of application-specific setup adjustments
• Two line by 24-character-per-line descriptive, plain-English display
• Process variable display in bar graph and engineering units
• Comprehensive plain-language, self-diagnostic message display
• Real-time motion information and historical fault log
• RS-232/422/485 for communication with process controllers
• Optional software for managing the drive from a personal or handheld computer

Reliable Operation

• Tolerant of AC line fluctuations
• Extensive electronic protection circuits reduce failures
• Optically isolated signals for high noise immunity
• S-curve acceleration reduces shock and extends equipment life
• Fiber-optics for noise-free serial communication
• Designed to meet or exceed accepted international standard
