Product Description:

The Kollmorgen PRD-AX50B00H-0A belongs to the CD Servostar range to operate in industrial settings.

The device offers both Analog Velocity Control (OPMODE 1) and Analog Torque Control (OPMODE 3) operational settings to help users design flexible motion systems across different situations. The drive product line offers continuous current options at 3, 6, and 10 amperes, which fit different motor specifications and required operating loads. The PRD-AX50B00H-0A regulates motors with high efficiency through its 16 kHz PWM switching system. The cycle sensor handles data at 16 kHz to give fast 62.5 µs current management that meets robust standards. The analog input works with 10-volt signals and uses a 12-bit A/D converter plus dual gain technique to create 15-bit precision that works best when the input voltage is low. The device supports encoder feedback processing of up to 3 MHz to scale then 12 MHz original frequencies. Users can select encoder output resolutions that reach 65,536 quadrature counting rotations in one revolution to achieve very precise positioning results. The system works with 5 VDC power in its encoder circuits.

This drive system provides complete integration with resolvers through its feedback features. It can handle 0.47 resolver transformation while working between 7 kHz and 8 kHz modulation frequency. The resolver receives 4.25 VAC power for its inputs and accepts resistances up to 120 ohms DC while using no more than 55 mA AC-RMS drive current. The drive accepts and processes the 2 VAC position signals that it receives from the resolver. The drive opens when a 12–24 Volt DC signal enters an optical isolation unit. This protection method provides secure power activation from the outside world. It can be purchased at Wake Industrial with a one-year warranty.
