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.
