Stand Alone Operation

In a stand-alone mode the indexer can operate independent of the host computer. Once downloaded to the non-volatile memory motion programs can be initiated from various types of operator interfaces, such as a keypad or switch, or through the auxiliary I/O inputs. A stand-alone stepper motor control system is often packaged with a driver and/or power supply and optional encoder feedback for "closed loop" applications that require stall detection and exact motor position compensation.
