I am using normally closed induction proximity switches. Can I stop the motor when the limit input sees a +5V signal?
Since All I/O at the connector is 5VDC TTL Level, only 5VDC or Dry contact switches should be used. There are various ways to use limit switch inputs. They can be set to Active High asserted or Active Low asserted depending on Firmware revision. Version 4.76 firmware ad above default to Active High only. Note: 24VDC converters are available for the motor I/O connector as well. Please consult the factory for more detail.
