3 axis 55v 3 amp drive board
|
Three axis microstepping drive and power supply board
This high performance micro-stepper drive card was designed to complement our low cost
AMC-E stepper, standalone machine control card. It can be neatly
mounted either above, below, or beside the AMC-E stepper machine
control card and connected to it via one ribbon and one 3 pin power cable.
|
|
The drive card incorporates 3 axes of motor drives, machine safety circuits, power supplies for both
the AMC-E and the stepper drives, and status indicators.
Connections to your machine are made via plug in screw terminal connectors.
|
|
|
|
|
|
Intended applications for the 3 axis stepper driver include: engraving machines, routing machines, milling machines,
lathes, and dispensing machines.
Due to its capability of operating at high voltages and of supporting selectable high micro-stepping
resolutions, the drive is capable of running your machine very rapidly, smoothly and quietly, and overcomes
many of the resonance problems that occur when using coarser step resolutions.
