General Information
4
The MCBL2805 was designed for Faulhaber
brushless motors with linear hall sensors. This
means that, even without an external encoder,
low speed and positioning with a resolution up
to 1/1000th of a revolution are possible. The
motion controller is based on a powerful 16-bit
microcontroller with excellent filtering quality.
This intelligent motion controller performs the
following tasks:
■Velocity Control: High performance speed
synchronization and the lowest possible
torque variance even in the most demanding
of applications. A PI-Controller makes sure
that the command velocity is accurately
achieved.
■
Velocity Profiles: Ramping, triangle, trapezoidal
and more complicated combined velocity
profiles are available to the user.
■Positioning Mode: Positioning with high
resolution including limit switches and zero
referencing.
■Additional Modes: For example, Stepper
Motor Mode to synchronize multiple motors.
■Torque Controlling: Achieved through current
regulation.
■Saving and Running Program Sequences: For
stand-alone positioning applications and to
relieve the host PC.
Inputs and Outputs:
■Command Value Input: For inputing command
speed values in digital or analog form. This
input can also interpret a reference mark
signal. Depending on the Mode, a frequency
signal or a incremental encoder can be
connected at this input.
■Fault Output (Open Collector): This output can
also be programmed as a direction of rotation
input, a digital input, or reference mark input.
■Third digital input
■RS-232 Ports: For connecting a host PC and
controlling program sequences.
Setting the Parameters and
Configurations
All filter settings can be set over the RS-232 port
and saved to the onboard memory (EEPROM).
Configuration settings (operating modes,
in/outputs, etc.) can likewise be saved.
Therefore, depending on the operating mode,
the motion controllers can function fully in
stand-alone applications.
Programming
A complete ASCII command set is available for
programming and operating the motion con-
trollers. All that is necessary is a terminal pro-
gram such as the Windows Hyperterminal.
The “FAULHABER Motion Manager” program is
available for users of Windows 95/98/NT. This
program makes configuration and operation
easy and allows the user to perform an online
graphic analysis of the performance of the drive.
