INPUTS/OUTPUTS
Feedback: Two channels of A/B quad-
rature per axis with third channel
for index. In servo mode, includes
auxiliary encoder inputs for each
axis. Single-ended or differential.
Can be configured for quadrature,
pulse and direction, or from ana-
log inputs.
General purpose inputs:
DMC-1510 thru 1540: 8 optoisolated
inputs
DMC-1550 thru 1580: 24 total
inputs (16 optoisolated, 8 TTL)
General purpose outputs:
DMC-1510 thru 1540: 8 TTL outputs
DMC-1550 thru 1580: 16 TTL outputs
General purpose analog inputs: 7 Inputs;
±10 V, 12-bit resolution (16-bit
optional)
Dedicated inputs per axis: Forward and
reverse limits, high-speed position
latch, home.
Dedicated outputs per axis: Analog motor
command, pulse and direction,
amplifier enable, encoder output
compare.
Axes: 1, 2, 3, 4, 5, 6, 7 or 8 axes
