Applied Motion 7080 - Manual (Page 2)

Technical Specifications
-15- -2-
Dual, MOSFET H-bridge, 3 state, pulse width modulated
switching at 25 kHz. 18 - 80 VDC input. 0.8 - 7.0 amps/phase
output current, switch selectable in 0.2 amp increments. 550
watts maximum output power. Overcurrent and overtemperature
protection. Automatic idle current reduction (defeatable),
reduces current to 50% of setting after one second.
Step, direction and enable, optically isolated, 5-12V logic. 2
mA/V/signal, sink requirement. (24V logic can be used with
current limiting resistors.) Motor steps on rising edge of step
signal current. 0.25 µsec minimum pulse width, 2 MHz max
step rate. 2 µsec minimum set up time for direction signal.
Fault output, optically isolated, becomes active if an over
temperature or overcurrent (short circuit) fault occurs.
16 switch selectable resolutions. Steps per revolution with 1.8
motor: 200, 400, 1000, 2000, 5000, 10000, 12800, 18000,
20000, 21600, 25000, 25400, 25600, 36000, 50000, 50800.
Waveform: pure sine standard. Other waveforms available upon
request. Other resolutions available upon request.
Switch selectable self test rotates motor slowly in alternating
direction, for testing drive & motor without input signals.
Mounted on 1/4 inch thick black anodized aluminum
heatsink/chassis. 2 x 3 x 6 inches overall. Power on and fault
indicators. See drawing on page 14 for more information.
Maximum chassis temperature: 70 C.
Screw terminal blocks.
Motor: 4 position, accepts AWG 12-28 wire
DC Input: 2 position, accepts AWG 12-28 wire
Signal Input: 8 position, accepts AWG 16-28 wire
