Product Description

The ACJ-090-12 DC servo drive is engineered for applications demanding robust motor control and accurate performance. It supports advanced servo mechanisms with high efficiency functionality and compact design.

This Accelnet series servo drive incorporates digital and analog motor encoder inputs using differential line receivers with R-C filtering. It terminates input signal pairs with a 121 resistor to ensure compatibility with cable characteristic impedance. It also features hall signal inputs (U, V and W) sourced from magnetic sensors or encoders which operate at lower frequencies for feedback and commutation initialization. The drive's PWM output employs a 3 phase MOSFET inverter with a 15 kHz center weighted PWM and space vector modulation to deliver smooth operation. The PWM ripple frequency is optimized at 30 kHz to enhance motor control efficiency. Protection is built in with current limiting to 750 mA at 1 V DC under overload conditions. It ensures that encoder position data is retained by deriving power from a + 24 V DC source even during AC mains power interruptions.

The Copley Controls ACJ-090-12 DC servo drive provides a dedicated encoder power supply rated at + 5 VDC with a 400 mA output to power encoders and Hall sensors. The motor cabling recommendations include shielded twisted pair cables for noise rejection and optimal signal integrity. Encoders utilize A-/A, B-/B, and X-/X twisted pairs for differential outputs that ensures accuracy and immunity to electrical noise. This servo drive is designed to meet the demands of precision applications. It incorporates robust protections and high performance features for efficient motor control and feedback. It is a reliable solution for industrial automation applications requiring accurate and continuous operation under varied load conditions.
