Configuration with CTSoft

CTSoft is a drive configuration tool for commissioning, optimising and monitoring CT drives. It allows you to; use the configuration wizard to commission your drive; read, save and load drive configuration settings; manage the drive’s Smartcard data; and visualise and modify the configuration with live animated diagrams.

Intelligently driven

Mentor MP allows the drive system designer to embed automation and motion control within the drive, eliminating communication delays that reduce performance while CTNet, a high performance drive-to-drive network links the different parts of the system.

Repair icon

Repairs

With 35+ years of repairing industrial automation parts there’s not many DC drive problems we haven’t encountered. We have bespoke test facilities in place to fully load test DC drives and regularly repair drives up to 450kW. All of our DC drive repairs come with a 12 month warranty and our no fix no fee promise.

Troubleshooting icon

Troubleshooting

If you are experiencing a fault or error code with your Mentor MP head to the downloads section and grab the manual which lists all of the fault codes and their meanings. Alternatively you can also give us a call, as an official Mentor MP distributor our factory-trained engineers are experienced in solving all faults on the Mentor MP range.

Upgrading from Mentor II

Mentor II to Mentor MP upgrade

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 and software tools have been developed to assist transfer of drive parameters and programs. If you are planning to upgrade your DC system, whether it is a Mentor or other manufacturer’s drive, Mentor MP is the clear choice.


The new FXMP25 replaces the existing FXM5 option. It may be controlled digitally by the Mentor MP or Mentor II using a standard RJ45 patch lead or ribbon cable respectively, allowing set-up by standard drive parameters. The FXMP25 has the same physical dimensions as the existing FXM5, but extends its current range to 25A. In standalone mode it is configured by its own keypad and display.


There are large numbers of DC motors in service throughout the world in various applications, the majority of which are easily capable of providing continued service. Many of these DC motors are controlled with old analogue DC drives like the Lenze 490 series and Siemens Simoreg series. Upgrading your analogue drive allows you to maximise the motor performance, enhance system reliability and interface digitally with modern control equipment using Ethernet and fieldbus networks. If you’re worried about downtime, Northern Industrial’s onsite engineers can retrofit your DC drive for you with minimal downtime.

Greater Field Control

Mentor MP field control

Every Mentor MP has a field controller as standard. This will enable the control of the majority of DC motors encountered in the market today. However, for the following situations, the optional FXMP25 external field controller is offered:

  • > The required field current is greater than that offered by the standard drive, but not greater than 25A. For example, older motors with low field voltages.
  • > The field is required to be forced down more quickly than is possible with the standard half controlled field bridge. For example, on spindle motors or motors with high field time constants where the field is required to weaken more quickly than the natural time constant of the field winding.
  • > The application can be implemented with simple field current reversal, without armature reversal. For example, applications where a rapid change in torque direction is not required. With the Mentor MP it is possible to implement a four quadrant system with a two quadrant armature converter where a slow change in torque direction can be tolerated.

How to find your Mentor MP part number

You can find the part number for your Mentor MP drive on the front of the unit. The Mentor MP numbers usually follow a particular format, for example MP1200A4R with each part of the number indicating something about the unit, such as amp rating, supply voltage and the number of quadrants.
