Product Overview1-1514C Product ManualChapter 1 Product OverviewDESCRIPTIONThe 514C controller is intended for use in an Industrial Environment, it should be mountedwithin an enclosure which provides protection to the controller and the user.The controller should be permanently earthed at the terminals provided.The 514C controller is designed to control the speed of a DC Shunt wound or permanentmagnet motor. It will provide control of the motor speed in all 4 Quadrants of operation.The controllers are designed to operate from a single phase AC mains supply in the range of110 Vac to 415 Vac at 50 or 60 Hz. An auxiliary supply is required for internal power supplygeneration and main supply contactor sequencing. Coding is derived from the main powerterminals and is functional over the whole input voltage range.The Speed of the DC Motor is controlled using a linear closed loop system with a feedbacksignal from either tachogenerator or armature voltage, the feedback source being switchselectable.A current loop within the speed loop always ensures that controlled levels of current areapplied to the motor, actual levels being scaleable via programmable switches.Motor protection is provided by a Stall detection circuit which will remove current from themotor after approximately 60 seconds.Controller protection is provided by an Instantaneous Overcurrent trip circuit overridingcontrol in the event of a Short Circuit.PRODUCT RANGEProduct Rating514C-04 4A DC Full Load Current514C-08 8A DC Full Load Current514C-16 16A DC Full Load Current514C-32 32A DC Full Load Current540 TO 514C UPGRADEThe 514C is designed to be functionally equivalent to the 540 series controllers not a directreplacement. Comparisons between the two controllers connectors are included throughoutthe manual.Chapter 2 describes the terminal connectors to the 514C controller, in that section on page 2-4is given a terminal to terminal comparison of 540/1 to 514C.This manual was downloaded on www.sdsdrives.com+44 (0)117 938 1800 - info@sdsdrives.com
