1. Connect the feedback signal cable.
Detector Connector
High–resolution magnetic pulse coder JY5
2. Set the detector–related parameters.
Parameter Setting Description
4001 #5 1 Uses a high–resolution
magnetic pulse coder.
4001 #6 1 Also uses a position detection
signal for speed detection.
4003 #7, 6, 5, 4 Depends on the detector. Sets a position coder signal.
4011 #2, 1, 0 Depends on the detector. Sets a speed detector.
4001 #2 1 Uses a position coder signal.
