Mentor MP

25A to 7400A Two or four quadrant operation (regenerative)
24V - 480V / 500V - 575V / 500V - 690V

Mentor MP brings DC drive technology up to date, enabling existing and new DC motors to provide economic and productive service. DC drive technology remains cost effective, efficient and is relatively simple to implement. For new applications DC drive provides many advantages, especially for regenerative and high power applications.

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

Current ratings

The power ratings for the 480V, 575V and 690V configurations are shown below.

The continuous current ratings given are for a maximum ambient temperature of 40°C (104°F) and an altitude of 1000m (3,300ft). For operation at higher temperatures and altitudes de-rating is required. Overload of 150% for 30s is available with ambient temperature of 40°C (104°F) up to a maximum of 10 repetitions per hour.
