Type
Description Suggested Action
01027
Autotune Diag VP, Flashing
red
Soft
The drive encountered a problem
while running the auto-tune tests.
When this condition occurs, the
drive coasts to a stop regardless
of the selected stop type.
Check Autotune Errors (parameter 176). For additional
information about Autotune Errors, refer to Chapter 13,
Understanding the Auto-tuning Procedure.
01051
MtrOvrld Pnd VP, Flashing
red
Soft
A motor overload is pending. The
drive has reached 95% of the
level required for a motor
overload trip (see fault 01052).
Check for possible motor overheating.
If the motor temperature is excessive, reduce the
accel/decel times (parameters 42 – 45) or reduce the
load.
If the motor temperature is acceptable, increase the
value of Motor Overload % (parameter 26).
If you do not want this condition to be reported as a fault,
change bit 3 in Fault Select 2 (parameter 22) to 0.
01052
MtrOvrld Trp VP, Flashing
red
Soft
Motor overload tripped. The drive
has reached the level of
accumulated motor current over
time as set by Motor Overload %
(parameter 26).
Check for possible motor overheating.
• If the motor temperature is excessive, reduce the
accel/decel times (parameters 42 – 45) or reduce the
load.
• If the motor temperature is acceptable, increase the
value of Motor Overload % (parameter 26).
If you do not want this condition to be reported as a fault,
change bit 4 in Fault Select 2 (parameter 22) to 0.
01053
Mtr Stall VP, Flashing
red
Soft
The drive is in a limit condition for
a period of time in excess of the
value specified in Motor Stall
Time (parameter 25) with the
motor at zero speed. Check Torque Limit Sts (parameter 87) to see which limit
has occurred. Increase the appropriate limit parameter
or reduce the load.
If you do not want this condition to be reported as a fault,
change bit 5 in Fault Select 2 (parameter 22) to 0.
01083
MtrOvrld Pend VP, Flashing
green
Warning
Motor overload pending. The
drive has reached 95% of the
level required for a motor
overload trip (see fault 01084).
Check for possible motor overheating.
If the motor temperature is excessive, reduce the
accel/decel times (parameters 42 – 45) or reduce the
load.
If the motor temperature is acceptable, increase the
value of Motor Overload % (parameter 26).
If you do not want this condition to be reported as a
warning, change bit 3 in Warning Select 2
(parameter 23) to 0.
01084
MtrOvrld Trp VP, Flashing
green
Warning
Motor overload tripped. The drive
has reached the level of
accumulated motor current over
time as set by Motor Overload %
(parameter 26).
Check for possible motor overheating.
If the motor temperature is excessive, reduce the
accel/decel times (parameters 42 – 45) or reduce the
load.
If the motor temperature is acceptable, increase the
value of Motor Overload % (parameter 26).
If you do not want this condition to be reported as a
warning, change bit 4 in Warning Select 2
(parameter 23) to 0.
01085
Mtr Stall VP, Flashing
green
Warning
The drive is in a limit condition for
a period of time in excess of the
value specified in Motor Stall
Time (parameter 25) with the
motor at zero speed.
Check Torque Limit Sts (parameter 87) to see which limit
has occurred. Increase the appropriate limit parameter
or reduce the load.
If you do not want this condition to be reported as a
warning, change bit 5 in Warning Select 2
(parameter 23) to 0.
