Mentor MP

Greater motor field control

• Built in field controller as standard
• Gives excellent field control for the majority of DC motors
• Reduces the need for external components

Enhanced field control with FXMP25

• The FXMP25 may be controlled digitally by using a standard RJ45 connection, allowing set-up by standard drive parameters
• The FXMP25 can also function in standalone mode using its integrated keypad and display

Enhanced system design

• The heatsink cooling fans are intelligently controlled and only run when required, thus increasing reliability and reducing maintenance
• Eighteen different option modules allow customisation of the drive, including fieldbus, Ethernet, I/O, extra feedback devices and motion controllers
• The drive system designer is able to embed automation and motion control within the drive, eliminating communications delays that reduce performance

Fast set-up, configuration and monitoring

Retro-fit projects

• Easy integration with your existing motor, power supply, application equipment and communication networks has been ensured from the design stage
• Mentor MP brings performance and possibilities to your application with minimum migration costs

Ease of migration

• Mentor MP has been designed so existing Mentor II customers can easily migrate to the new platform
• All power terminal locations and mounting points have been retained
• Mentor MP has a much smaller frame size than the 900 A Mentor II with paralleling options to offer high power density
• CT Soft has a built in migration wizard to assist with the transfer of drive parameters and programs
• Smaller cable requirements make connections within the cubical easier. Construction of a custom-made bus-bar is not required

Motor Field Control

• Built in field controller as standard in every Mentor MP
• Gives excellent field control for the majority of DC motors
• Reduces the need for external components

An external motor field controller is recommended when:

• The required field current is greater than that offered by the standard drive, up to 25 A. For example, older motors with low field voltages
• The field is required to be forced down more quickly than is possible with a standard half controlled field bridge
• Applications can be implemented with simple field current reversal, without armature reversal, if machine dynamics can still be met

• Models available for two or four quadrant (regenerative) operation


• 25A to 7400A, 24V - 480V / 500V - 575V / 500V - 690V


• Optional high-brightness LED or multi-language LCD keypad, simple configuration using plain text


• Modular parallel connection for higher power motor operation


• 12/24 pulse operation to minimize harmonics


• IP20 (NEMA 1) protection for size 1, IP10 (open chassis) for size 2A and 2B, and IP00 (open chassis) for size 2C and 2D for easy, low cost installation


• Integrated drive and motor protection for:
• Over current
• Over temperature
• Phase loss
• SCR/Thyristor junction temperature
• Feedback loss
• Field loss
• Armature open circuit


• Internal field controller with intelligent field weakening means that for 90% of applications no additional external controller is required
• Frame size 1 to 8A
• Frame size 2 to 20A
• Flux control for enhanced open loop performance


• Optional FXMP25 external field controller for current fields up to 25A
• Digital link for field control from Mentor MP or Mentor II
• Standalone digital control mode for simple application
• Flux control for enhanced open loop performance
• Intelligent field weakening
• Field forcing – for high dynamic machine reversal
• Field reversal – low dynamic machine reversing using two quadrant main stack


• Mentor MP has a field control mode for fields requiring greater than 25A


• Serial port for Modbus RTU and PC communications


• 3 Universal option module slots, allowing Mentor MP to benefit from the solutions developed for Control Techniques market leading AC drive technology.
  Each option slot allows:
• High performance PLC and motion control
• Ethernet and Fieldbus communications
• Connectivity to additional feedback devices
• Additional I/O


• Galvanically isolated control


• Smartcard for drive parameter back-up and copying, allowing rapid installation and maintenance


• Integrated PLC as standard


• Standard software features for easy integration
• PID controller
• Motorized potentiometer
• Digital lock (Slave operation from master encoder)


• Open loop control using estimated speed advanced processing based on armature voltage and field flux feedback


• Closed loop control using
• Tacho-generator feedback for connection to traditional DC motor
• Incremental encoder feedback for higher accuracy and position control
• Optional SinCos, SSI, Hiperface and EnDAT connectivity for high performance applications


• High performance control strategy
• 32 bit microprocessor
• 35μs current sampling time
• Speed controller and ramps update 250μs
• Autotune features for armature, field current loops and speed loop
