Oak Troubleshooting
Symptom
Possible Cause
Corrective Action
All status LEDs out
Logic power not applied
Measure AC coming into power
supply, correct wiring or supply
problems
5, 3.3, 12, or -12 LED out
Power supply or
connection problem
Measure AC coming into power
supply, correct wiring or supply
problems
MPU11 not ready
Wait for MPU11 section to start and
enter run mode
FPGA LED not lit
Internal Fault
Return for repair
DSP LED not lit
MPU11 section is booting
up
Wait for MPU11 section to detect
hardware and start run mode
DSP DEBUG LED
flashing fast
MPU11 section is
detecting hardware
Wait for MPU11 section to detect
hardware and start run mode
DSP DEBUG LED
flashing one time per
second
New drive protocols
active
None
DSP DEBUG LED
flashing two times per
second
Legacy drive protocols
active
Internal fault, only new protocols
should be in use, return for repair
Encoder connection bad
Bad encoder or wiring
Check or replace encoder and cable
Return not connected
Connect return line. If the encoder
is not powered by Oak's +5V, this is
sometimes overlooked.
DF LED out
Motion control processor
section hasn't booted up
Start software, wait for the main
screen to load
"Servo Power Removed"
due to fault
Restart system to reset runaway or
other serious fault condition
PLC OK LED out
Motion control processor
section hasn't booted up
Start software, wait for the main
screen to load
LED1 display flashing
with decimal point lit
An error condition has
been detected
See the "LED1 Error Codes" section
for details on the error
Input doesn't work with
sensor
Incorrect wiring
Correct wiring for sensor type
(sinking or sourcing), check that
SIP values are appropriate for the
input voltage
Voltage drop across
sensor is too high
Use 3-wire sensors with lower
voltage drop spec.
