Hello, gentlemen! I am stuck with the machine, because it seems that there are no step and dir pulses coming from 7i43 card. I have 4 stepgens for 4 joints and I do not see any output from any of them. I am using 7i43 400K version, SVST-4_12.BIT firmware on EMC 2.4.6
In INI file I have: [AXIS_0] TYPE = LINEAR MAX_VELOCITY = 150 MAX_ACCELERATION = 200 BACKLASH = 0.000 SCALE = 314.96 MIN_LIMIT = -3.0 MAX_LIMIT = 1000.0 FERROR = 0.50 MIN_FERROR = 0.10 HOME = 0.000 HOME_OFFSET = 0.0 HOME_SEARCH_VEL = -5 HOME_LATCH_VEL = 1 HOME_USE_INDEX = NO HOME_IGNORE_LIMITS = NO HOME_IS_SHARED 1 HOME_SEQUENCE 0 DIRSETUP = 2000 DIRHOLD = 2000 STEPLEN = 4000 STEPSPACE = 4000 In HAL file I have: # X [0] Axis # axis enable chain newsig emcmot.00.enable bit sets emcmot.00.enable FALSE net emcmot.00.enable <= axis.0.amp-enable-out net emcmot.00.enable => hm2_[HOSTMOT2](BOARD).0.stepgen.00.enable # position command and feedback net emcmot.00.pos-cmd <= axis.0.motor-pos-cmd net emcmot.00.pos-cmd => hm2_[HOSTMOT2](BOARD).0.stepgen.00.position-cmd net motor.00.pos-fb <= hm2_[HOSTMOT2](BOARD).0.stepgen.00.position-fb net motor.00.pos-fb => axis.0.motor-pos-fb # timing parameters setp hm2_[HOSTMOT2](BOARD).0.stepgen.00.dirsetup [AXIS_0]DIRSETUP setp hm2_[HOSTMOT2](BOARD).0.stepgen.00.dirhold [AXIS_0]DIRHOLD setp hm2_[HOSTMOT2](BOARD).0.stepgen.00.steplen [AXIS_0]STEPLEN setp hm2_[HOSTMOT2](BOARD).0.stepgen.00.stepspace [AXIS_0]STEPSPACE setp hm2_[HOSTMOT2](BOARD).0.stepgen.00.position-scale [AXIS_0]SCALE setp hm2_[HOSTMOT2](BOARD).0.stepgen.00.maxvel 170 setp hm2_[HOSTMOT2](BOARD).0.stepgen.00.maxaccel 230 setp hm2_[HOSTMOT2](BOARD).0.stepgen.00.step_type 0 I checked these things: 1) stepgens are enabled, at least the enable pins are "true" in HAL Config; 2) stepgen-pos-cmd values are changing, they receive position commands from joints; Why I think that there is no output: 1) none of motors moves or shows any kind of activity; 2) with multimeter, when measuring volts, I should see something above 0.00V on step pin and definitely more on dir pin in one of 2 directions - I jogged both directions, nothing happened on any of stepgen outputs. Why do I think that problem is in Mesa card: 1) I removed some other LPT breakout board few hours ago, everything was working with it, I am using existing wiring; 2) I triplechecked, if step and dir leads are soldered to correct pins on 50-pin header and that it is connected to P3 connector. What am I missing here? Viesturs ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable. Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
