RTA GMD 03 Stepper Motor Drive

The RTA GMD 03 is a bipolar chopper drive realized with SMD technology in a single EUROCARD format card (100×160 mm). It is backward-compatible with previous series equipped with a 32-pole, DIN 41612 form D connector, making it suitable for multi-axis applications requiring such compatibility. The drive is designed to be assembled inside a rack complete with a motherboard. It features electronic damping to reduce acoustic noise and mechanical vibrations at low and medium speeds. Standard input and output signals facilitate interfacing with common control systems. The drive operates with a single external power supply and includes protections against under-voltage, over-voltage, short-circuits at motor outputs, and overheating.

Features:

• Operating Voltage: 55-85 VDC
• Current Range: 4-10 Amps, adjustable via dip-switches
• Microstepping Options: 200, 400, or 800 steps/revolution, selectable via dip-switches
• Automatic Current Reduction: Engages when the motor is at standstill
• External Motor Current Disable: Allows motor current to be switched off via an external logic signal
• Protections: Under-voltage, over-voltage, short-circuit at motor outputs, and overheating
• Electronic Resonance Damping: Reduces acoustic noise and mechanical vibrations at low and medium speeds
• Backward Compatibility: Mechanically and electrically compatible with previous series drives
