4-6 Troubleshooting
Port 1-5 DPI Loss 81 - 85
➁
The DPI port stopped communicating. 1. Check the HIM connection.
2. If adapter was not intentionally disconnected, check
the wiring to the port. Replace the wiring, port
expander, adapters, Control Board or complete drive
as required.
3. If an adapter was intentionally disconnected and the
bit for that adapter in Par 591
[Logic Mask] is set to
“1”, this fault will occur. To disable this fault, set the
appropriate bit in [Logic Mask] for the adapter to “0.”
Power Failure 3
➁
There is a fault in the 24V Control board supply -
the voltage is below the permitted value. In most
cases the cause is in the external I/O wiring.
• Pull the plug-in I/O terminal blocks out of the control
circuit board and reset the drive via 1347
[Fault
Clear]. If there are no other faults, check the I/O
wiring for a short-circuit including the cable
shielding.
• Check fuses F1 and F2 located on the Switching
Power Supply circuit board (frame A size drives only
have one fuse - F1). Replace as necessary.*
• Check varistor fuses F1, F2, and F3 on the Pulse
Transformer or Transient Noise Filter circuit boards
for Frame C size drives. Replace as necessary.*
• If this fault occurs again, an internal fault may be
present. Contact your Rockwell Automation sales
office.
*Note: Refer to Control Power Circuit Protection
Fuses on page A-15 for fuse sizing information.
STune Aborted 62
➁
The speed regulator auto tuning procedure has
been stopped by the user.
Informational only.
STune CurLimit 59
➁
The value of Par 1048 [Autotune Cur Lim] for auto
tuning the speed regulator is set too high.
Decrease the value of Par 1048 [Autotune Cur Lim]
and repeat the auto tune procedure.
STune FrictionLo 60
➁
The friction value attained during the auto tuning
procedure is zero or lower than the control
precision limit.
Decrease the value of Par 1048
[Autotune Cur Lim]
and repeat the auto tune procedure.
STune LoadHi 58
➁
The loading torque value is too high at zero speed
to complete the speed regulator auto tuning
procedure.
Decrease the load torque, where applicable, and
repeat the auto tune procedure.
STune Overspeed 56
➁
The measured motor speed is too high during the
speed regulator auto tuning procedure.
Decrease the value of Par 1048 [Autotune Cur Lim]
and repeat the auto tune procedure.
STune Stalled 57
➁
The drive stalled during the speed regulator auto
tuning procedure.
Increase the value of Par 1048 [Autotune Cur Lim] and
repeat the auto tune procedure.
STune Timeout 61
➁
The speed regulator auto tuning procedure did
not complete within the available time.
Verify the value in Par 1048 [Autotune Cur Lim]. If this
value is set to low, the motor will not be able to reach a
maximum speed of 33% of the lower of the values in
Par 45
[Max Ref Speed] or Par 3 [Max Speed Fwd] or
Par 4
[Max Speed Rev] and not be able to complete
the test. Set these values appropriately and repeat the
auto tuning procedure.
Sustained Curr 70
➁
The motor CEMF is too high or the line voltage is
too low.
• Check the line voltage and frequency.
• Check the motor brushes and connections.
• Check the Main and DB Contactor connections if
present.
• Verify that there are no overhauling loads present.
