Fault messages and list of faults
70
Timeout DPx-
SSI No
response
Coded fault; only with DPA11A.
Code 1: SSI interface fault. SSI module defective.
Inform SEW Service if fault cannot be reset or
if it occurs frequently.
Code 2: Communication
fault of SSI interface.
SSI module defective.
Code 3: Parity or power
failure fault from SSI
encoder. • Encoder cable disrupted
• Electrical power supply disrupted
• Incorrect setting of machine parameters
• Check encoder cable
• Check electrical power supply
• Check machine parameters and correct if
necessary
Code 4: Lag error in SSI
module Data transfer between encoder and DPA11A
disrupted. Check connection cable and associated
shield.
71
Timeout DPx-
CAN No
response
Coded fault; only with DPA11A.
Code 1: Timeout CAN. CAN bus communication interrupted. Check the CAN bus connection.
Code 2: CAN receive buffer
full.
Systematic program error caused by
excessively frequent writing of CAN bus
interface of an inverter.
Reduce write accesses to inverter concerned
in user program.
Code 3: CAN controller
overflow.
CAN controller malfunction.
Inform SEW Service if fault cannot be reset or
if it occurs frequently.
Code 4: CAN controller
error. Malfunction on the CAN bus. Possibly, no
nodes are present.
Check wiring and user program.
72 Index overrun
No
response
Only with DPx11A:
Fault with indexed variable index. Offset
variable Cxx greater than C99 selected.
Correct user program.
73
Unauthorized
command No
response
Only with DPx11A:
Command was transmitted which cannot be
carried out in current status of inverter. For
example, transmitting the SAVE command
during a positioning process.
Check user program.
74 Range limit
No
response
Only with DPx11A:
Calculated setpoint position in increments
greater than 230 and therefore located outside
range limit.
Check user program.
77
IPOS control
word No
response
Only in IPOS operating mode:
•
Attempt was made to set an invalid
automatic mode (via external control).
• P916 = BUSRAMP set.
• Check serial connection to external
control.
• Check write values of external control.
• Set P916 correctly.
78
IPOS SW limit
switches No
response
Only in IPOS operating mode:
Programmed target position is outside travel
range delimited by software limit switches.
• Check user program
• Check position of software limit switches
81 Start condition
Immediate
switch-off
Only in "VFC hoist" operating mode:
Current during premagnetization phase could
not be injected into motor at a high enough
level:
•
Motor rated power too small in relation to
inverter rated power.
• Motor cable cross section too small.
• Check startup data and repeat startup
procedure if necessary.
• Check connection between inverter and
motor.
• Check cross section of motor cable and
increase if necessary.
82 Output open
Immediate
switch-off
Only in "VFC hoist" operating mode:
•
Two or all output phases interrupted.
• Motor rated power too small in relation to
inverter rated power.
• Check connection between inverter and
motor.
• Check startup data and repeat startup
procedure if necessary.
84
Motor
protection Emergency
stop
•
Motor utilization too high.
• Reduce load.
• Extend ramps.
• Observe longer pause times.
85 Copy
Immediate
switch-off
Fault when copying parameters. Check connection between inverter and PC.
88 Flying start
Immediate
switch-off
Only in "VFC n-CTRL" operating mode:
Actual speed > 5000 rpm when inverter
enabled.
Enable only at actual speed
≤
5000 rpm.
92 DIP work area
Emergency
stop
Only with DIP11A option:
Drive has moved beyond the permitted work
area of the absolute encoder. Setting of
encoder type/work area DIP parameters may
be incorrect.
Check position offset and zero offset
parameters.
