SD-700 STEPPING MOTOR DRIVER
A
MOTOR DRIVER FOR 3 STEPPING
MOTORS, WITH POWER SUPPLY
Drives
3 motors - taking up only 70 x 30 x 206 mm (2.75 x 1.18 x 8.1 Inches).
Optically
isolated inputs for high noise immunity.
Built-in
power supply for motor and logic - only power transformer needed.
STEP, DIRECTION,
FULL/HALF STEP, ENABLE control inputs.
Current limiting
resistor for each drive.
Interfaced
to standard TTL level signals.
Operating
software for PC available (for up to 6 motors).
Low-cost -
only $110 per motor.
Single, dual
and triple motor drivers available.
AC
input voltage: 12 - 24 Vac (rms). DC input voltage
(if power supply not used): 14 - 32 Vdc (motors) + 5 Vdc (logic). Transformer
current : sum 
of phase currents
x 1.5. (example: 3 motors of 1 Amp/phase each, will require a 4.5 Amp transformer).
Isolation: all
control inputs are optically isolated. Input levels:
TTL compatible level. Input current:
High - 5 mA, Low - 0 mA. Input levels:
High - 3.5 - 5.5 V, Low - 0 - 2 V. Chopping frequency:
18 or 25 kHz. (please specify). Stepping rate:
up to 20,000 Steps/Sec. Operating Temperature:
-20� to +50�C. Operating Humidity:
5% - 95%. Physical dimensions
(H x W x L):- One motor driver with power supply: 30 mm x 70 mm x 106 mm.
- Two motor driver with power supply: 30 mm x 70 mm x 156 mm.
- Three motor driver with power supply: 30 mm x 70 mm x 206 m.
- Above drivers without power supply (DC operated): reduce 30 mm from length.
