text: <s>[INST] Motor Encoder Connector on U3000 Since my motor encoder do not have pinout of overtravel limit, I leave +LIMIT/-LIMIT pins open on CN2. After I startup the driver, there is an Error Code L flashing which means the drive is in overtravel condition. The manaual indicates that the motion will be halt if +LIMIT/-LIMIT circuit is open. I wonder if I can just jump +LIMIT/-LIMIT with EMPWR_5V (or ECOM?) to skip the detection of overtravel. YC [/INST] If you're using a standard Rotary motor, those pins are not active. If you're using a standard Linear Motor, those pins could be active, but only in case where the encoder has this feature. If you're using a custom Rotary or Linear motor, then the parameter could be enabled in the Motor database configuration. Open the Motor window inside Ultraware and look for Integral Limits in General group, if there is yes then the HW overtravel are enabled. If not, then the overtravel error could come from other ways, like configured Inputs of the drive, or from Programmable Software Overtravel limits. Please check first if the Integral Limits parameter is active, then post again, with possibly more details about your configuration and motor. - fuzzy logic Please remember to Rate the Comments( ) to enhance the reputation of the User who provided help,or close your Topic using the ( ) button over the answer that solved it.
