Remedy Cause Description Fault message Remedy Cause Description
Display No.
x087 Sd7 Selection of the feedback in
C0025 as absolute value encoder
or alteration of the encoder
constant in C0420 for setting
C0025
³ 309
The absolute value encoder must
be initialised. Save parameter set, then
completely deenergise the device,
and afterwards switch it on again.
Initialisation error of absolute
value encoder at X8 l Defect of the encoder
electronics
l Absolute value encoder at X8
does not send data.
Tip: The encoder must not rotate
during mains switching.
l Make sure that the cable at X8
is tightened properly, and
check it with regard to open
circuit.
l Check absolute value encoder
with regard to correct function.
l Set voltage supply via C0421 to
8.0 V.
l No Stegmann encoder
connected.
l Replace defective encoder.
Communication error of absolute
value encoder at X8 during rotor
position adjustment A rotor position adjustment via
C0095 = 1 could not be completed
successfully. Repeat rotor position adjustment.
Note: After an Sd7 fault it is
absolutely required to carry out
another rotor position
adjustment. Otherwise the drive
may carry out uncontrolled
movements after controller
enable. The drive must not be
commissioned without a
successfully executed rotor
position adjustment!
After fault elimination:
Completely deenergise device
(switch off 24 V supply, discharge
DC bus)!
x088 Sd8 SinCos encoder at X8 sends
inconsistent data. The tracks in the SinCos encoder
are damaged. Replace SinCos encoder.
Interference level on the encoder
cable is too high. l Check correct shield
connection of encoder cable.
l Where required, decelerate the
actuation of the fault message
via the filter time constant.
Setting:
– for ECSxS/P/M/A in C0559.
– for 9300 servo cam in C0575.
SinCos encoder at X8 does not
send any data. Open circuit. Check cable for wire breakage.
Incorrect encoder connected. Connect SinCos encoder of the
Stegmann company.
SinCos encoder is defective. Replace SinCos encoder.
Supply voltage set incorrectly. Set voltage supply in C0421.
After fault correction: completely
deenergise the device (switch off
24 V supply, discharge DC bus)!
x089 PL Error during rotor position
adjustment (the error is saved
with mains failure protection) l The rotor position adjustment
was cancelled.
l During rotor position
adjustment with an absolute
value encoder the error Sd7 or
SD8 occurred.
Repeat rotor position adjustment.
Note: After an Sd7 fault it is
absolutely required to carry out
another rotor position
adjustment. Otherwise the drive
may carry out uncontrolled
movements after controller
enable. The drive must not be
commissioned without a
successfully executed rotor
position adjustment!
