SAB
9.3.1 Troubleshooting
Table 9.4 lists potential faults on the SAB, their possible
causes, and actions for correcting the faults.
Fault Possible cause Possible solution
LCP display dark
or has no
function.
Missing input
power.
Check the input power
source.
Missing or open
fuses or circuit
breaker tripped.
Check the fuses and circuit
breaker.
No power to the
LCP.
•
Check the LCP cable for
proper connection or
damage.
•
Replace any faulty LCP
or connection cables.
Incorrect
contrast setting.
Press [Status] + [
▲
]/[
▼
] to
adjust the contrast.
Display is
defective.
Replace the faulty LCP or
connection cable.
Fault Possible cause Possible solution
Open power
fuses or circuit
breaker trip.
Phase-to-phase
short.
•
Check the cabling.
•
Check for loose
connections.
DC-link voltage
too high.
Brake resistor
not connected.
Check the brake resistor
cabling.
Brake resistor
too high
resistance.
Check if the lowest
resistance value has been
entered.
Several servo
drives are
decelerating
with insucient
ramp time.
•
Avoid simultaneous
deceleration of several
servo drives.
•
Change the deceleration
speed of the servo
drives.
Brake resistor
functionality not
activated.
Activate the brake function.
