First of all, I think it will be better to correct the TO settings to the real values, like I did in the ScreenShot "Mechanics": Gear settings (Load gear): -> Number of motor revolutions = 1000 (-> Number of teeth of the load wheel) -> Number of load revolutions = 2117 (-> Number of teeth of the motor wheel) -> Leadscrew pitch = 785,4 mm/rot (= 250mm * 3,14159... circumference of the driving wheel) Furthermore I think, the encoder is mounted at the motor. So the settings above will be better for this mounting scenario (always use the real values of the application! :-) ). The use of the N-signal of the encoder is, because of the gear-box and the mounting of the encoder at the motor, is not a good way. There will be too many signal edges of the N-signal on a very short distance the vehicle moved. To get the right is very difficult... The use of MC_Home with mode = 0 is also not the best way, because of the jitter of OB1 is influencing the accuracy of setting the homing position. A better way is to use the passive homing functionality of the TO. For this, see picture "PassiveHoming" and use mode = 10 of MC_Home, by setting up the homing position at the TO configuration (-> Home position) With the setting Homing direction = current and Homing mark = positive side, the TO uses always the edge of the homing signal with the greater position value (-> see online help) I think, this will work... :-) Note: AttachmentTIA-Settings.zip (393 Downloads) |
