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 SETUP
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 SPPED AND POSITIONING LOOP
This allows several drives to be run in speed or position synchronization.
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.
