Overview
Mentor MP is Control Techniques' new DC drive and integrates the control platform from the world's leading intelligent AC drive, Unidrive SP. This makes Mentor MP the most advanced DC drive available, giving optimum performance and flexible system interfacing capability.
Applications
Our extensive expertise across a wide range of industries mean that we are the ideal partner for DC solutions.
Typical applications for Mentor MP include:
• Metals
• Printing
• Material handling
• Rubber and plastic
• Pulp and paper
• Crane and hoist
• Mining
• Elevator and escalator
• Active front end for DC Bus connected AC Drive systems
Benefits
• Mentor MP allows DC motor performance to be optimised, enhance system reliability and interface digitally with modern control equipment using Ethernet and Fieldbus networks
• Mentor MP inherits the world beating control platform and software tools from Control Techniques AC drive range, so you retain the flexibility of changing to an AC drive system in the future if your application requirements evolve.
• Every Mentor MP has a motor field controller integrated as standard up to 10A and the FXMP25 option extends this to 25A. 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
• Mentor MP is fully RoHS compliant and worldwide certifications include CE and cULus
• Mentor MP allows the drive system designer to embed automation and motion control within the drive, eliminating communication delays that reduce performance while CTNet, our high performance drive-to-drive network, links the different parts of the system
• Mentor MP is quick and easy to set-up. The drives may be configured using a removable keypad, Smartcard or the supplied PC commissioning software that guides the user through the configuration process
• Mentor MP is an ideal retro-fit choice with features to ensure it can integrate easily with your existing DC motor, power supply, application equipment and communication networks. Mentor MP brings new performance and new possibilities to your application
• 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
Control Techniques has a patent pending to protect one unique aspect of the Mentor MP design. Galvanic isolation between power and control is a standard feature in AC drives and, in the case of failure, protects the control circuits and connected equipment from high voltage on the power circuit.
Mentor MP uses a novel technology to achieve Galvanic Isolation without compromising performance or reliability.
