ANUAL
Default case when loading capstan
constants
When capstan is not off when switching to
servo control
No capstan tach pulses are detected when
changing capstan speeds
No capstan tach pulses are detected when
changing capstan speeds
No capstan tach pulses are detected when
in jog
Capstan tach pulse period is outside
acceptable range
Capstan can't get to target speed within 5
seconds when slowing down
Capstan can't get to target speed within 5
seconds when speeding up
Capstan FG error feedback from servo chip
is not within range after 5 seconds
immediately following a speed change
If capstan not off and current direction is
not the same as the desired direction
If capstan target speed is not a servo-
defined speed
When capstan is not off when switching to
servo control
If capstan target speed is illegal (format)
No drum tach pulses are detected when
drum is turned on
Drum is already turned full on when servo
lock is attempted
Drum jitters for more than 5 seconds when
starting up
Drum not at target speed (measured with
µP) within 5 seconds
Drum not at target speed (measured with
servo chip) within 5 seconds
Drum speed feedback from servo chip is
not stable within 2 seconds
