The IM1007 is small, easy to interface and use, yet powerful enough to handle the most demanding applications. The IM1007 has 14 different resolutions (both in binary and decimal) built into the driver. These resolutions can be changed at any time. There is no need to reset the driver. BLOCK DIAGRAM This feature allows the user to rapidly move long distances, yet precisely position the motor at the end of travel without the expense of high performance controllers. The development of proprietary circuits has minimized ripple current, while maintaining a 20 kHz chopping rate. This prevents additional motor heating that is common with drivers requiring higher chopping rates. Now low inductance stepper motors can be used to improve high speed performance and system efficiency. The IM1007 also comes with an optional on-board indexer to provide design engineers with versatility and power unmatched in today’s industry. The IM1007 is priced lower to provide customers with affordable state-of-the-art technology for that competitive edge needed in today’s market.
