F480
Fieldbus command
velocity too high.
"Fieldbus command velocity exceeds
VL.LIMITP."
"Lower fieldbus command trajectory,
or increase the value of VL.LIMITP."
F481
Fieldbus command
velocity too low.
"Fieldbus command velocity exceeds
VL.LIMITN."
"Increase fieldbus command trajec
-
tory, or decrease the value of
VL.LIMITN."
F482
Commutation not initial-
ized.
"Themotor requires the commutation
initialization (there are no encoder
commutation tracks, Hall sensors,
etc.) and no successful Wake and
Shake sequence has been per-
formed"
"Clear any faults, activate theWake
and Shake procedure (WS.ARM)
and enable the drive."
F483
Motor U phasemissing.
"No current was detected in the
motor's U phase during Wake and
Shake initialization (Mode 0 only)."
"Check themotor connections and
WS.IMAX (very low current may
produce this error)."
F484
Motor V phasemissing.
"No current was detected in the
motor's V phase during Wake
and Shake initialization (Mode 0
only)."
"Check the motor connections and
WS.IMAX (very low current may
produce this error)."
F485
MotorW phasemissing.
"No current was detected in the
motor's W phase during Wake
and Shake initialization (Mode 0
only)."
"Check the motor connections and
WS.IMAX (very low current may
produce this error)."
F486
"Motor velocity exceeds
EMU-speed."
"Motor velocity exceeds themaximum
speed the emulated encoder output
can generate."
Reduce value of DRV.EMUE
-
PULSEIDTH.
F487
Wake and Shake - Vali-
dating Positive Move-
ment Failed.
After applying a positive current, mo-
tor moved in the wrong direction.
"Check motor phase wiring and
motor encoder wiring is correct."
F489
Wake and Shake Vali-
dating Negative Move-
ment Failed.
After applying a negative current,
motormoved in the wrong direction.
"Check motor phase wiring and
motor encoder wiring is correct."
F490
Wake and Shake -
Validating Comm. angle
timed out.
"During one of the W&S validation
stages, the drive stopped responding
to commands."
Contact customer support.
F491
"Wake and Shake -Vali-
dating Comm. angle
moved too far - Bad
Comm Angle."
"After applying a current, the
motormoved too far (>15 electrical
degrees)."
"This indicates a poor motor phase
angle was found by Wake and
Shake. Revise Wake and Shake
parameters, and re-run Wake and
Shake."
F492
"Wake and Shake - Vali-
dating Comm. angle
required more than
MOTOR.ICONT."
"A current larger than MOTOR.
ICONT was used to excite the
motor."
"This indicates one of the following:
Phase angle is incorrect due to a
bad wake and shake. Motor has
very high friction requiring high
current to break free. Motor power
cable is disconnected or improperly
wired."
