Checklist for startup and service
Tape attached per FMEA?
Correct orientation of tape to sensor head?
Optional: Cover tape applied?
Sensor head attached per FMEA? Torque setting________
Sensor head correctly connected (electrical)?
Supply voltage correct?
Output signals have correct polarity and phase?
All connectors plugged in?
Cable strain relief on sensor head?
Cable routed so that interference from other cables is prevented?
Maximum distance between sensor head and tape not exceeded over the entire range of motion?
Lateral offset between sensor head and tape not exceeded over the entire range of motion?
120-Ω termination resistor between differential signals +sin/−sin and +cos/−cos connected/enabled?
Function check with manual movement: Do all signals +sin, −sin, +cos, −cos arrive at the controller with correct
amplitude and phase?
Direction of the electrical signals correct?
Pointer length determination Z = (A² + B²) enabled?
Function check: motorized movement at maximum speed?
Is the pointer length at maximum travel speed correctly determined?
