Potential Root Causes

Root Cause	Indicators	Tests	See Also	Pic
SY Linear Bearing Seized	Cannot turn the leadscrew (it should turn easily in your fingers)	Is the lubrication getting to the bearing?	SY Lubrication manifold needs grubscrew "blocker". See ECN005
Leadscrew seized	Cannot turn the leadscrew (it should turn easily in your fingers)	Lubrication?
Spacer between motor and motor mount not fitted	Coupling inside SY axis bottoms out
SY axis coupler slipping	Intermittent SY axis losing datum position
Centraliser pressure too high
Datum sensor faulty	Sensor light flickers Datum position wanders	Physically mark the zero position. Using the drive screen repeatedly home the axis and check zero
Datum sensor cable faulty	Intermittent cable connection can cause the SY axis datum position to change	and wiggle the cables - see if the datum position moves or the sensor light flashes
SY Motor Failure	Intermittent problems SY Motor Quality issues since m/c Z097
SY Motor Cable failure
SY axis drive failure
48v PSU failure	Rarely an intermittent fault
48v PSU cable failure
