Description: The Si3540 is a programmable step motor drive/indexer packaged in a rugged steel and aluminum enclosure. Integral heat sink, mounting brackets, switch covers and connectors are included with each Si3540. The Si3540 has been matched with twelve recommended NEMA 11, 14, 17 & 23 frame step motors, and comes with all operating software necessary to create a complete step motor-based motion control solution. The Si3540 includes Applied Motion Products' Windows-based Si Programmer™ software application for quick set up and ease of use. Si Programmer™ is ideal for stand-alone operation. For users with software development expertise, the Si3540 can also be used with Applied Motion's Si™ Command Language (SCL). SCL allows for control of an Si drive, like the Si3540, via serial commands sent from a host device such as a PC or PLC. This permits the user to perform a variety of motion, I/O, and system status tasks via a host serial device. Multiple axis applications can be handled with the SiNet™ Hub Programmer software, which gives you the ability to control up to 8 Si drives, stepper and servo, from just one SiNet Hub 8. Not only can you sequence up to eight motors, but a SiNet Hub 8 also has access to the inputs and outputs of all the drives connected to it, providing your program with up to 64 inputs and 24 outputs. The SiNet Hub 444 connects up to 4 Si drives, and comes with 4 digital inputs and 4 digital outputs of its own.You can also use Applied Motion's MMI-01 to interface the drives with the machine operator. Factory set to operate at 110 VAC input; the Si3540 can be set by the user to operate at 220 VAC input by a simple switch selection. Pluggable screw terminal blocks are provided for the I/O, motor, and AC power input. Mating connectors, programming cable with computer interface connector, as well as all operating software are provided with each Si3540 drive. The Si3540 is both CE and TUV compliant.
