8. Crane Drive Faults
The A1000 Crane Drive has incorporated 13 additional faults to those on the standard A1000 inverter. In this section
those faults are described along with possible causes and solutions.
Display Fault Name Description
Corrective
Action
Fault Type
OL3 Overtorque Detection 1
Triggered when the Overtorque Detection 1 function is enabled (S6-01=1 to 6) and
the drive’s Internal Torque Reference (vector control) or Output Current (V/f
control) exceeds the Overtorque Detection Level 1 (S6-02) for longer than the
Overtorque Detection Time 1 (S6-03).

or S6 parameter
settings
A
(when S6-01 = 3 or 4)
B
(when S6-01 = 1, 2, 5, or 6)
OL4 Overtorque Detection 2
Triggered when the Overtorque Detection 2 function is enabled (S6-04=1 to 6) and
the drive’s Internal Torque Reference (vector control) or Output Current (V/f
control) exceeds the Overtorque Detection Level 2 (S6-05) for longer than the
Overtorque Detection Time 2 (S6-06).

A
(when S6-04 =3 or 4)

OL5 Overload Detection
Triggered when the Overload Detection function is enabled (S5-01 = 1 to 6 for
overload detection 1, or S5-04 = 1 to 6 for overload detection 2) and the drive’s
Internal Torque Reference (vector control) or Output Current (V/f control) exceeds
the Overload Detection Level (S5-02 for overload detection 1, and S5-05 for
overload detection 2), for longer than the Overload Detection Time (S5-03 for
overload detection 1 and S5-06 for overload detection 2)

(when S5-04 = 5 or 6)
B
(when S5-01 = 1 thru 4)
(when S5-04 = 1 thru 4)
OL6 Ultra Lift Acceleration 2 Fault
Triggered when the Ultra Lift 2 function has been enabled (using S4-01 or a digital
input), the drive’s output frequency is higher than the Ultra Lift 2 Activation Frequency
and the Drive’s Output Power exceeds the level set to S4-15 (Ultra Lift 2 Fault
Detection Level) for a time longer than S4-16 (Ultra Lift 2 Fault Detection Time).

A
(when S4-14 = 0, 1, 2)

(when S4-14 = 3)
OPE24 Parameter Setting Fault Ultra Lift 1 and Ultra Lift 2 have both been selected at the same time.

OPE11 Parameter Setting Error
The following parameter relations are not being met:
C6-05 (carrier frequency proportional gain) > 6, and C6-04 (carrier frequency lower
limit) > C6-03 (carrier frequency upper limit)
C6-03 to C6-05 upper/lower limit error
Check parameter
settings.

OPE22 Parameter Setting Error
The following parameter relations are not being met:
When the brake delay time (S1-04) ≠ 0 and the
Brake Release Frequency (S1-01, 02) ≤ brake delay frequency (S1-03)
When slip prevention time (S1-15) ≠ 0, and
Brake release frequency (S1-12, 13) ≥ slip prevention frequency (S1-14)
Impact Stop Function (H1-xx = 35) has been set to multi-function input, and the
impact stop clip frequency (S3-01) > brake release frequency (S1-12, S1-13)
Although the Brake Release Check has been set to multi-function digital input
(H1-xx = 0), the brake release command has not been set to multi-function digital
output (H2-xx = 21).
Check parameter
settings.

OPE23 Parameter Setting Error
While using a vector control mode, one of the following parameters is set to a
value greater than the torque limit for the motoring direction (L7-01, L7-02).

OPE25 Parameter Setting Error
A multi-function input terminal set to switch to motor 2 has been triggered while the
following incorrect data is set for motor 2:
Brake release frequency (S1-01, S1-02) is less than or equal to brake delay
frequency (S1-03) while at the same time the brake delay time in S1-04 ≠ 0.
Brake close frequency (S1-12, S1-13) is greater than or equal to the slip
prevention frequency (S1-14) while at the same time the slip prevention time
S1-15 ≠ 0.
The impact stop creep frequency (S3-01) is greater than the break close frequency
while at the same time a multi-function input terminal is set for “Impact stop”
(H1-xx = 35).

Fault Types:
A: Fault (motor coasts to stop, flashing operator display, fault relay tripped, brake clamped shut).
B: Minor Fault (continue running, operator display will flash, no fault relay tripped, minor error relay tripped (if selected).
C: Alarm (operation not possible, operator display flashes, no fault relay output, no minor error relay output).
