Mentor MP

Description

Drive intelligence and system integration

Mentor MP has an inbuilt controller programmable with SyPTLite. Develop tailored solutions for applications modules with SyPTPro, SyPTPro is a fully featured automation development environment that can be used for developing tailored solutions for single or multiple drive applications. Create an intelligent networked system with CTNet. Which is a high-speed, deterministic drive-to-drive network links the drives, SCADA and I/O together form an intelligent networked system, with SyPTPro managing both the programming and communications.

Machine communications flexibility

Option modules for all common Industrial Ethernet fieldbus networks such as Ethernet IP & ProfiNet. Servo networks such as Ethercat are also available. SM-Applications & CTNet allow machine designers to design an easy gateway into which customers are able to interface using their preferred fieldbus or Ethernet interface. This solution improves the machine performance, simplifies the problem of being able to meet customer specifications for different fieldbus communications & helps to protect your intellectual property.

Features

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

  • Quick and easy to set-up
  • Can be configured using optional removable keypads
  • Advanced autotune features help you get the best performance from your machine
  • PC software and Smartcard tools for rapid commissioning
  • Intelligent networked system with CTNet
  • Program inbuilt controller with SyPTLite
  • Develop tailored solutions for applications modules with SyPTPro
  • Option modules for all common Industrial Ethernet, fieldbus networks

 

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

Specifications

  • 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
