The Yaskawa CACR-SR20SB1AFY100 is designed as a variable frequency drive (VFD) specifically for AC motor applications. This model receives a 3-phase input with a voltage range of 200 to 230 VAC, functioning on either 50 or 60 Hz frequency settings. The drive employs a closed-loop vector control method for optimal speed regulation. It is capable of overseeing motor power levels up to 2.0 kW, equating to 2.7 horsepower, thus supporting a variety of typical industrial motor requirements.

Mounting is facilitated through a panel-mounted design using a through-hole configuration. The unit provides encoder feedback with a precision of 6000 pulses per revolution, which is crucial for accurate positioning and speed management. The output current rating stands at 9.5 A when operating at 200 volts, ensuring consistent motor performance.

Tolerance thresholds allow this drive to handle overloads of 150% for a duration of 60 seconds and even 200% for short instances of 3 seconds, which is beneficial for overcoming temporary load spikes in certain applications. Communication with the unit is available through an analog voltage input of ±10 VDC, along with a differential pulse train input for enhanced control.

For braking, the drive utilizes a dynamic braking method, necessitating an external resistor for effective operation. The carrier frequency adjustable range spans from 1 to 15 kHz, giving users the ability to fine-tune it based on noise and performance demands. With an ingress protection rating of IP20, the unit is suitable for internal applications, while the output frequency can be tuned from zero up to approximately 400 Hz, allowing for extensive flexibility in controlling AC motor functions.
