Configuring the NI ISM-7413
The NI ISM-7413 is configured in software with the NI Stepper Configuration Utility, available
at
ni.com/downloads
. When you have located your device with the utility, you can configure
various aspects of the motor performance and control for your application.
The ISM can be set to one of two motion command modes. Pulse and Direction mode accepts a
signal such as that generated by an external indexer or motion controller.With this mode, the
frequency of the pulses fed into the STEP input determines the speed, and the signal fed into the
direction input determines the direction.
Streaming command mode allows the user to command motion with a command stream over
Ethernet. In this comand mode, the STEP, DIR, and EN inputs can be used to accept input from
limit switches.
