Remedy Cause Description Fault message Remedy Cause Description
Display No.
0079 PI Fault during parameter
initialisation l An error has been detected
during the parameter set
transfer between two devices.
l The parameter set does not
match the controller, e.g. if
data has been transferred from
a higher−power controller to a
lower−power controller.
l Correct parameter set.
l Send parameter set (on floppy
disk/CD−ROM) and a detailed
description of the problem to
Lenze.
x082 Sd2 Resolver error at X7 Resolver cable interrupted. l Check cable for open circuit.
l Check resolver.
l Switch off the monitoring
(C0586 = 3).
x083 Sd3 Encoder error at X9 Cable interrupted. Check cable for open circuit.
Pin X9/8 not connected. Apply 5 V to pin X9/8 or switch off
monitoring (C0587 = 3).
x085 Sd5 Encoder error at X6/1 and X6/2
(C0034 = 1) Current signal at X6/1 X6/2 <
2mA. l Check cable for open circuit.
l Check current signal encoder.
l Switch off monitoring
(C0598 = 3).
x086 Sd6 Motor temperature sensor error
(X7 or X8) Encoder for detecting the motor
temperature at X7 or X8 indicates
undefined values. l Check cable for firm
connection.
l Switch off the monitoring
(C0594 = 3).
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.
^ 6.8−1
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)!
