Dual, bipolar MOSFET H-bridge, pulse width modulated three
state switching at 20kHz. 12-42 VDC input. 0.4 - 3.5
amps/phase output current, switch selectable in 0.1 A
increments. 122 watts maximum output power. Automatic idle
current reduction (switch selectable), reduces current to 50% of
setting after one second.
Step, direction and enable, optically isolated, 5V logic.
5mA/signal, sink requirement. Motor steps on rising edge of
step input. 0.5 µsec minimum pulse width. 2 µsec minimum
set up time for direction signal.
Mounted on 1/4 inch thick black anodized aluminum heat
transfer chassis. 1.5 x 3.0 x 4.0 inches overall. Power on red
LED. See drawing on page 14 for more information. Maximum
chassis temperature: 70
°
C.
European style screw terminal blocks. Max wire size: AWG 18.
Motor: 4 position (A+, A-, B+, B-)
Signal Input: 4 position (+5, STEP, DIR, EN)
DC Input: 2 position (V+, V-)
Switch selectable, rotates motor 1/2 revolution each direction at
100 steps/second, half step mode.
Four switch selectable step resolutions. With 1.8¡ motor:
Half step (400 steps/rev)
1/5 step (1000 s/r)
1/10 step (2000 s/r)
1/64 step (12,800 s/r)
Other resolutions, up to 12,800, available to qualified OEMs
upon request.
Complies with EN55011A and EN50082-1(1992).
