Mentor II
|
|
El Mentor II ofrece variadores para motores de corriente continua completamente programables con una interfase de control única adaptable a una amplia gama de potencias.
Las aplicaciones simples stand-alone son rápidamente configuradas con un mínimo de parámetros. Añada el módulo de aplicación (MD29) para implementar una alta performance con inteligencia local. Esta inteligencia puede ser utilizada para eliminar la necesidad de un PLC master, construyendo un sistema de control distribuido, usando el CTNet fieldbus con el software de programación System Programming Tool (SYPT). Se dispone además de una gama de módulos de comunicación para diferentes buses de campo en el caso de desear la integración con sistemas de control existentes.

Key benefits
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 Mantor 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 synchronisation.
Centrewinder
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.
