NOTE:
= Index pulse not detected or lost
= Unable to maintain spin speed within 0.5%
= Loss of +FINE TK. during idle mode
= More than one seek retry
= Time out on +END DECEL signal
= Time out on track crossing (-CYL PULSE)
= Overshoot
= Time out on +FlNE TK
= +TKO signal not detected on a seek to TKO
= Comparator mismatch during settling
= Comparator mismatch after track crossing .
= Unexpected interrupt from microprocessor
= Time out on TKO pattern
= Time out on GB1 pattern
= Time out on GB2 pattern
= Seek range error
= Voltage unsafe with -WRTGATE inactive
= Voltage unsafe with -WRI'GATE active
= Chip unsafe (-WRI'TE FAULT)
= Step pulses received with -WRTGATE active
= Time out on +END DECEL signal
= Time out on track crossing (-CYL PULSE)
= Overshoot
= Time out on +FINE TK
= +TKO signal not detected
= Comparator mismatch after rezero
= Servo adjust failure - no closure
= 6301 Trap
