The P261 Series of Drives and the P261X Series of Drive/Indexer Systems are compact microstep systems that provide cost effective solutions for most motion control applications. The P261 packaged drive section is a stateof-the-art microstep drive utilizing surface mount technology with the translating and power stages needed to control virtually any hybrid step motor. By combining the ultra efficient MOSFET amplifiers, versatile H-bridge technology, and microprocessor controlled logic, the P261 provides outstanding speed/torque performance.

The P261X Indexer section automatically generates precise ramping routines; interfaces to your environment through the use of RS-232 communications, limit inputs, and programmable I/O; and for applications utilizing encoder capabilities, position maintenance and stall detection are available.
