Product Description:

The CR06261 CD drive utilizes a resolver as its control transmitter type and can be operated stably through the application of a modulation frequency of 7 to 8 kHz. It features an input voltage of 4.25 VAC provided straight from the drive unit. This model has a maximum DC resistance of 120 ohms on the stator. The motive is capable of supporting a maximum 55 mA AC-RMS current and is appropriate for low-current high-precision resolver applications.

The CR06261 also supports a cable tolerance length of up to 50 feet or 15 meters of encoder interface with a maximum recommendation of not exceeding the same in an attempt to ensure stable operation. Sinusoidal commutation and six-step commutation are offered as user-selectable options based on the firmware setting. Double commutation mode offers additional flexibility for use in other motors. Feed-back encoder system can take 3 MHz maximum frequency so that it can process high-rate data signals efficiently. Incremental feed-back capability can be obtained through normal A and B signals as an option by including an additional Z or H marker signal in order to enable safe pulse tracing and indexing capabilities. These encoder inputs prefer wide universes of motion applications with high accuracy and feedback resolution.

The CR06261 drive offers the control and responsiveness to deliver servo systems that need resolver input and real-time feedback control. This ability of this model to handle mixed signal types and stable currents allows for precise feedback interpretation. It is designed to be in service over the long term in resolver-based servo loops. It is employed in tasks that need robust speed control, noiseless signal switching, as well as extended encoder cable lengths. Having rigid integration and firmware-based flexibility, this model gives adaptable solutions for servo synchronizations in resolver feedback applications.
