Upgrading your control system
There are large numbers of DC motors in service throughout the world in various applications, the majority of which are easily capable of providing ongoing service and Transdrive are DC Drive specialists in upgrading your DC drive from old analogue technology to Mentor MP digital technology that allows you to maximise the motor performance, enhance system reliability and interface digitally with modern control equipment using Ethernet and Fieldbus networks. Downtime is minimised as only the drive needs to be replaced.
Driving forward with DC technology
DC drive digital technology remains cost effective, efficient and is relatively simple to implement. For new applications DC provides many advantages, especially for regenerative and high power applications.
Mentor MP has been engineered as an easy replacement for Mentor II. It has the same physical dimensions and connection layout. Software tools have been developed to easily migrate to the new platform.
Mentor MP set-up, configuration and monitoring
Setting the Mentor MP parameters is quick and easy. The drives can be configured using the removable keypad, the Smartcard or a PC. The auto tune and easy parameter-setting functions ensure that the best performance is obtained by measuring the motor and machine characteristics and automatically optimising the control parameters. Existing Mentor ll users benefit from our free migration wizard software.
PC software and Smartcard tools for rapid commissioning
Control Techniques’ software suite makes it easier to access the drive’s full feature set. It allows you to optimize the drive tuning, back-up the configuration and set-up a communications network. The software tools can connect using Ethernet, Serial, USB or Control Techniques drive-todrive network, CTNet. Migration tools make the process of transferring parameter sets from Mentor II to Mentor MP a simple process. Please Call for further details.
User interface options
Mentor MP offers the choice between two keypads to meet the needs of your application.
Extra-bright LED display, hot pluggable.
Multilingual backlit LCD display, hot pluggable, plain text (English, French, German, Italian, Spanish, etc.) The display can be customised with specific text.
Smartcard: Storage memory provided with each Mentor MP.
- Storage and backup of parameter sets.
- Parameters can be copied from one drive to another.
- Backup automation programs.
- Quick configuration for sequential application building.
- Program availability.
Greater motor field control
Every Mentor MP has a motor field controller as standard which gives 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.
- Applications 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.
FXMP5 - External motor field controller
The FXMP25 may be controlled digitally by the Mentor MP 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. For older motors, with very low field voltages and field currents greater than 25A, the Mentor MP itself has a field mode, allowing it to be implemented as a field controller with no additional components.
