If another block is using the motor, fail. If the motor is already listed as being configured, re-configure it. (as a result you should not call this block again once the motor is configured, or it will start configuring again) text/html 2009-08-19T05:01:23+00:00 patbarnes http://www.ti2.com.au/wiki/4control:pc:stepper:steppermotor?rev=1250658083&do=diff StepperMotor is a data structure that stores all the state information and inputs/outputs relating to a single motor, as well as the parameters that motor is to run under. Parameters These parameters dictate the operation of the stepper motor. They should be set before using any of the stepper control function blocks. Do not change them in the middle of operations, or undefined behaviour may occur. text/html 2009-08-17T06:17:39+00:00 patbarnes http://www.ti2.com.au/wiki/4control:pc:stepper:stepper?rev=1250489859&do=diff This library is designed to simplify control of the Wago 750-671 stepper control card. The library has been tailored specifically for the NSA-12, but with some customisation could be used for another motor type.
