描述 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 software

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 programmable

outputs can send signals to other

electronic devices and activate relays.
