ACTUAL SIZE 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. Features • Can be programmed for stand alone operation with the easy to use Si Programmer™ Windows software (software and programming 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,
