Expands servo control
January 1st 2008 Offering control for servo and
stepper motor axes, together with
onboard I/O and fieldbus
connectivity, the new NextMove-
ESB2 from Baldor expands servo
control capability from three to four
axes. Combined with control for 4
stepper motor axes, and I/O for
material handling and general
machine control functions, the
NextMove-ESB2 module offers an
economic standalone solution that
can be used for a wide range of
machinery applications.
Based on an advanced DSP
core, NextMove-ESB2 delivers realtime
performance. It supports
servo loop closure times of 100
microseconds on the four main
axes, with six-term closed loop
control for accurate positioning
(PID, velocity, acceleration feed
forward, and velocity feedback).
Flexibility of control is aided by a
further free encoder input which
may be used as a 'master' axis.
Depending on the drives chosen,
the module's stepper outputs may
also be used for servo motor
control, making the module
capable of controlling up to eight
precision servo motor axes.
NextMove-ESB2's four stepper
axes provide pulse and direction
outputs at up to 500 kHz. More articles from Baldor UK Limited: |
