DC motors and drives
.
.
Thyristor / SRC DC motors and drives continue to be used in industries such as metal, cranes, mining and printing. The current trend is to replace DC systems with new AC motors and drives to reduce maintenance costs; however, it is often a major task that requires putting machines out of service for a long period of time while the necessary mechanical and electrical renovations are carried out.
The most attractive alternative is usually to use the existing DC motor and retrofit the DC drive. In general, DC motors are of good construction and last many more years in service, so their use generally reduces project costs considerably and minimizes interruptions and risks. Modern DC drives also offer many advantages. In addition to being based on current AC drive technology, Control Techniques DC drives offer high motor performance, reliability, and the ability to integrate with other systems.

Characteristics
Flexible systems integration
The Mentor MP is a modern DC drive based on current AC drive technology from Control Techniques. This means that you have inherited flexible systems integration features, such as:
Three slots for optional automation control, I / O, feedback and communication modules
SmartCard for storage of parameters and PLC program
Easy setup and monitoring software tools
Technology that guarantees reliability and performance
The Mentor MP represents a breakthrough in performance, endurance and reliability:
High performance motor control:
32-bit microprocessor
35 μs scan time
250 μs speed and ramp controller
Auto-tuning functions for armature, inductor current loops, and current loop
The galvanic isolation between the power and control modules protects the control circuits and other equipment connected to the drive against the presence of high voltages in the supply circuit. This feature is unique to DC drives and is patented.
Protection system against deficiencies in the industrial power supply and lightning strikes
Integrated motor and drive protection against:
Overcurrent
Overheating
Phase loss
Thyristor / SCR Junction Temperature
Loss of feedback
Loss of field
Armature circuit interruption
Flexible field control
Using an internal field controller with intelligent field weakening eliminates the need for an additional external controller in 90% of applications:
Integrated field control in sizes 1 to 8 A
Integrated field control in sizes 2 to 20 A
Flow control for advanced open-loop performance
External field control via FXMP25 up to 25A
Easy upgrade
The Mentor MP is designed to be a simple and updated version of the Mentor II. It has the same physical dimensions and power connections as this one. The software tools developed allow an easy migration to the new platform.
