Decentralized AC drive VLT® FCD 300

three-phasebuilt-inwall-mount

The VLT® Decentral Drive FCD 300 has reached the Limited phase of its lifecycle and is no longer in active production. Danfoss offers an extensive portfolio of low-voltage drives and will help you select the optimal replacement drive for your application. According to UL508C, frequency converters supplied as of May 9, 2013 shall be: a. Provided with motor load and speed sensitivity overload protection with thermal memory retention (ETR function),b. Provided with means to accept and act upon a signal from a thermal sensor or switch imbedded in the motor or from an external protection relay, or c. Marked to indicate that the equipment is not incorporating internal overload protection for the motor load and is intended to be used with external or remote overload protection. For any drive series not mentioned above or for units supplied with earlier software versions, ensure that: - The frequency converter is configured to react on input from a motor thermal sensor or switch [UL508C par 20.1.11 (b) and 56.7]. Refer to the Design Guide for wiring and programming information.. - The motor is equipped with an external over- temperature protection device [UL508C par 20.1.11 (c) and 56.7], or - The motor circuit includes a separate overload relay [UL508C par 56.6]. The VLT® FCD 300 PROFIBUS Converter MCA 117 changes the functionality of a VLT® Decentral Drive FCD 302 so that it can be used as a spare part for a VLT® Decentral Drive FCD 300 or a VLT® DriveMotor FCM 300. A VLT® Decentral Drive FCD 302 (0.37–2.2 kW (0.5–3.0 hp)) with flat bracket and adapter brackets (order number 134B6775) can be mounted using the same drilling holes as for the FCD 300.
