PROBLEMS & REMEDIES
Overhaul the control apparatus
Substitute the brake magnet
(see page 26)
Readjust the air gap in the brake
(see page 26)
Substitute the angular encoder
(see page 27)
Substitute the electromagnet
(see page 26)
Bring power supply up to specified
value
Eliminate the interruption
Delay in switching off the motor and
in the braking
Brake defective
Brake wear excessive
Angular encoder defective
Electromagnet defective
Power does not reach electromagnet
or voltage is below that specified
Break in the electrical leads
Turret does not stay locked
The turret continues to rotate
without stopping at the required
station
Correct the connection of the phases
(see page 30)
Inverted phases in the power supply
of the motor
Substitute the buffer pads
Bring the moment of inertia of the
masses in use down to a
permissible figure (see page 33)
Bring the moment of unbalance of the
masses in use down to a
permissible figure (see page 33)
Excessive travel of the buffer pads
Moment of inertia of the masses in
use is above the permissible maxi-
mum
Moment of unbalance of the masses
in use is above the permissible
maximum
The turret approaches the required
station by the longer path
Excessive shock in pre-indexing
Bring the moment of unbalance of the
masses in use down to a permitted
value (see page 33)
Moment of unbalance above the
permitted
Disk rotates in jerks
