Dual, bipolar H-bridge, pulse width modulated three state switch-
ing at 20.5kHz. 12-35 VDC input. 0.1 - 2.0 amps/phase output
current, software selectable. 70 watts maximum output power per
axis. Automatic idle current reduction (software selectable),
reduces current when motor is not moving.
Step/run 1, step/run 2, direction 1, direction 2. Differential,
optically isolated, 5V logic. 440 ohms internal resistance. Motor
steps on rising edge of STEP- input (and/or falling edge of
STEP+). 0.5 µsec minimum pulse width. 2 µsec minimum set up
time for direction signal.
0 to 5 VDC, 1K - 10K recommended impedance. 10 bit ADC.
Optically isolated (photodarlington) 30VDC, 100 mA maximum
Mounted on 1/4 inch thick black anodized aluminum heat transfer
chassis. 1.5 x 3.0 x 4.0 inches overall. Power on green LED.
