Mentor II

Digital DC Variable Speed Drive
25 A - 1850 A in Both Single and 4 Quadrant

Overview

DC drives are widely used in applications that require
regeneration, precise speed control, dynamic performance, and constant torque over wide speed ranges. The Mentor II
delivers the universal DC drive solution.
Simple stand-alone applications are easily configured to control motor speed, voltage or current using standard internal settings. Set-up is convenient using the drive keypad, CTKP remote keypad, or MentorSoft, a Windows based drive configuration tool. The Mentor II has extensive diagnostic and communication abilities that enhance system reliability. The drives standard yet powerful microprocessor is a versatile system component that can eliminate the need for a PLC with integral functions such as thresholds, timers and logic gates that perform basic control.

The simple addition of the MD29, a 32-bit application
co-processor card, provides high performance drive systemsm75-14m
with local intelligence for true distributed control. The MD29
enables users to incorporate custom or proprietary process
control application programs to their drive. The Mentor II also
provides a wide range of communication protocol options.
Mentor II systems have proven to be extremely reliable and
are ideally suited to web handling, winders, slitters, extruders, wire drawing, converting lines, and plastics production. The Mentor IIs integrated design and highly programmable features make it an ideal choice for OEMs and System Integrators, as well as replacement or retrofit drives for End Users.

Simple Operation
Easy set up of the drive can be done using the main control panel or via a standard communications interface from a host computer.

Fast configuration of standard applications can be achieved using 10 parameters or less.
Faster Drive Set-Up
Programming the Mentor II has never been easier. Designed to save commissioning time, the drive has easily assimilated function menus browsed and edited via five navigator keys.
Better Control
A comprehensive self-tuning algorithm gives improved current loop performance for a more uniform response at all speeds. Drive performance is also enhanced with full PID digital speed control.
More Functions
The main circuit board has been developed to incorporate many additional features as standard.
Massive Systems Potential
All analogue inputs and most of the digital control inputs are user-configurable, making Mentor II a true systems drive having more versatility and flexibility than ever before.
Wide Ranging, More Flexible Communications
Mentor II is able to communicate directly with PLCs and host computers or via optional interface cards. This is achieved with the standard RS485 port.
Digital Speed and Position Loop
This allows several drives to be run in speed or position synchronization.
Centre winder
The drive torque is continuously adjusted to compensate for changing coil diameter, machine losses and coil inertia.
Shaft Orientation
This allows the user to specify the final position of the motor shaft relative to an electronic feedback datum, for example a marker pulse from an encoder. The position is adjusted by simply changing the value of the appropriate parameter.
'S' Ramp
This facility provides a curved function at each of a user defined acceleration/deceleration ramp.
