1.1 Basics
1. General
The MCBL 05002 is a general-purpose controller for three-phase brushless motors. It has small
external dimensions and can be plugged into a normal IC-socket. It is ideally suited for effec-
tive operation of 0206 micromotors, but can also be used to control any other three-phase
motor. The drive will operate in open-loop mode, with no speed feedback from the drive to
the controller.
The controller has a range of inputs, making it suitable for various types of operation.
Potentiometers can be connected via analog inputs so that the drive can be manually controlled.
If the pulse input is used, the drive can operate as a stepper motor; via a serial interface the
drive can be connected to a PC or a PLC and operated accordingly. All drive parameters can be
adjusted via this programmer interface. Parameters can be stored and retained for re-use once
the unit is switched on again.
Technology
Extremely silent-running due to control via a three-phase sinewave signal (not PWM!).
Drives with low moment of inertia also run silently.
Smooth start-up and slowdown via acceleration and deceleration ramps in all drive modes.
Safer operation due to compensation of the induced back-EMF, so that the required
torque is near-constant.
Overcurrent protection via a peak current limiter, which operates when the maximum
permitted current is exceeded, to return the drive to a safe state.
Positioning moves the drive within 4 million revolutions with a resolution of 1/256th of a
revolution.
