Breathing new life into the DC market
The Mentor MP DC drive from Conrol Techniques Mentor MP is designed with both today's and future requirements in mind, its full system integration flexibility offering three option module slots and an inbuilt field controller. These economically priced option modules are common across Control Techniques' AC, DC and Servo drive ranges and include functionality extensions such as additional feedback options and expanded I/O and a powerful onboard programmable control. The range of optional fieldbus connectivity is unique, including Profibus-DP, Interbus-S, DeviceNet, CANopen and various Ethernet protocols such as Modbus TCP/IP, Ethernet/IP and EtherCAT. Communications gateway solutions can also be implemented easily and economically within the drive by installing two or three fieldbus option modules. The number of option modules will increase as Control Techniques develops new solutions for their complete range of drives.
The company says that the Mentor MP's standard inbuilt, field controller is all most users will ever need but an all new external field controller option, the FXMP25, provides field forcing for high dynamic applications; such as very fast reversing while a new feature allows reverse jogging control with two-quadrant drives for lower-cost systems that do not require fast reversal. In addition, Mentor MP has a field controller mode that allows itself to act as a field control for larger DC motors, where the field current can be greater than the capacity of the FXMP25.
Mentor MP uses Control Technique's suite of well-tried and tested software tools, developed to support the programming and drive configuration of its AC drive ranges. For example CT Soft, used for drive configuration, includes a configuration wizard allowing existing Mentor users to transfer drive settings from an existing Mentor II drive to the new Mentor MP. Existing Mentor II users will also appreciate the design results that make Mentor MP a simple retrofit, with the same mechanical footprint, main fixing centres and with power connections located in the same place as Mentor II.
