MP420A4-CC Nidec Control Techniques Mentor MP DC Drive

FEATURES

Flexible system integration

Mentor MP is a modern DC drive based on Control Techniques' current AC drive technology. This means that Mentor MP inherits the system integration flexibility, such as:

• Three option module slots for automation control, I/O, feedback devices and communications
• SmartCard for PLC program and parameter storage
• Software tools for easy configuration and monitoring

Technology for reliability and performance

Mentor MP takes a step forward in performance, robustness, and reliability:

High performance motor control:

• Galvanic isolation (patent pending) between power and control protects the control circuits and other equipment connected to the drive from the high voltages on the power circuit. This feature is unique on DC drives
• Protection system against poor quality industrial power supplies and lightning strikes
• Integrated drive and motor protection

Flexible field control

Internal field controller with intelligent field weakening means that 90% of applications require no additional external controller:

• Integrated field control on frame size 1 to 8 A
• Integrated field control on frame size 2 to 20 A
• Flux control for enhanced open-loop performance
• External FXMP25 field control to 25 A 

Easy upgrade

Mentor MP has been designed as an easy upgrade for Mentor II. It has the same physical dimensions and power connection layout. Software tools have been developed to easily migrate to the new platform.
