Description

FXMP25 Field Controller

The FXMP25 is an external field controller that may be connected digitally to a Mentor MP DC drive 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.

Easy upgrade

The new FXMP25 replaces our existing FXM5 option. It may also be controlled digitally by a Mentor II, 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. For field currents above 25A, a separate Mentor MP DC drive can be used as a field controller.

Easy to set-up and commission

Greater motor field control including built in field controller as standard. Enhanced field control with FXMP25, The FXMP25 may be controlled digitally by using a standard RJ45 connection, allowing set-up by standard drive parameters. Enhanced system design. The heatsink cooling fans are intelligently controlled and only run when required, thus increasing reliability and reducing maintenance. Quick and easy to set-up that can be configured using optional removable keypads

Features

 

Every Mentor MP has a motor field controller as standard that provides excellent field control for the majority of DC motors. However, for the following situations, the optional FXMP25 external field controller is recommended:

  • The required field current is greater than that offered by the standard drive, up to 25A. 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. 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.
  • FXMP25 allows applications to 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.
