PC-based board controls up to 4 axes
The DMC-1000 is a 32-bit programmable motion controller for the PC bus.
The board has one, two, three, or four axes of control. Usable with step
motors, servo motors, and hydraulics, the controller uses a 14-bit motor
command output D/A converter and a PID filter with velocity and
acceleration feedforward, and integration limits. Control is maintained
via an 8-million counts/s feedback encoder, a sample rate of 125
microsecond per axis, and a bidirectional FIFO for high-speed bus
communications with PC interrupts. Jerk is eliminated by programmable
acceleration and deceleration with S-curve profiling. External contact is
through eight opto-isolated digital inputs, eight digital outputs, and
seven analog inputs. Dedicated opto-isolated inputs are provided for
forward and reverse limits, amplifier enable, abort, home, and definable
input interrupts. (Single axis, $795; four axis, $1,195–stock to 10 days.
