1240i PROGRAMMABLE INDEXER/DRIVE
1240i PROGRAMMABLE INDEXER/DRIVE
Description
The 1240i is a low cost, programmable step
motor driver, suitable for a wide range of
motion control applications. It includes a
sophisticated controller integrated with a
50 watt microstepping amplifier.
The 1240i includes Applied Motion’s easy
to use
Si Programmer™
Windows soft-
ware for the rapid development of stand
alone motion control programs. The 1240i
can also be commanded in real time from a
host PC or PLC, using the
SiNet Command
Language™.
For multi-axis applications, up to eight 1240i
drives can be networked using the SiNet
Hub-8. The hub also allows the 1240i to be
mixed with any of the other six Si™ drive
models, fulfilling the exact requirements of
your application at the lowest possible cost.
The 1240i includes 8 programmable inputs
for triggering, branching, position sensing
and end of travel detection. 3 program-
mable outputs can send signals to other
electronic devices and activate relays.
Features
• Can be programmed for stand alone opera-
tion with the easy to use
Si Programmer™
Windows software (software and program-
ming cable included).
• Can be operated in real time from a host PC or
PLC using the
SiNet Command Language™.
• Requires 12 – 42 VDC power supply, up to
1.5 A.
• Programmable motor current: up to 1.2
amps/phase.
• Microstepping: 2,000 – 50,800 steps/rev.
• Speeds to 50 rev/sec.
• 20 kHz PWM amplifier with mixed fast/slow
decay.
• 8 optically isolated 5 – 24 V inputs can be
configured for sinking or sourcing logic.
• 3 optically isolated outputs, 30 VDC, 100 mA.
• Automatic idle current reduction.
• Drives 4, 6 or 8 lead step motors, sizes 11 – 23.
• Compatible step motors available from stock.
• Compact size (0.7 x 3.0 x 4.0 inches).
• Four .156 inch mounting holes, 2.7 x 3.7 inch
spacing.
• Screw terminal connectors.
