Causes
The monitor value set in H2-26
[Comparator 2 Monitor
Selection] was outside the range
of H2-27 [Comparator 2 Lower
Limit] and H2-28 [Comparator
2 Upper Limit].
A drive hardware problem
occurred.
The drive power supply was de-
energized while a
communication option entered a
parameter Write command.
An EEPROM peripheral circuit
error occurred.
A drive hardware problem
occurred temporarily due to
noise.
A drive hardware problem
occurred temporarily due to
noise.
The load is too heavy.
Acceleration and deceleration
times are set too short.
The dEv detection level settings
are incorrect.
The load is locked up.

Possible Solutions
Examine the monitor value and remove
the cause of the fault.
• Re-energize the drive.
• If the fault stays, replace the control
board or the drive. For information
about replacing the control board,
contact Yaskawa or your nearest sales
representative.
Set A1-03 = 2220, 3330 [Initialize
Parameters = 2-Wire Initialization, 3-
Wire Initialization] and initialize the
drive.
• Re-energize the drive.
• If the fault stays, replace the control
board or the drive. For information
about how to replace the control
board, contact Yaskawa or your
nearest sales representative.
• Remove the cause of the noise.
• If the fault stays, replace the control
board or the drive.
• Remove the cause of the noise.
• If the fault stays, replace the control
board or the drive.
Decrease the load.
Increase the values set in C1-01 to C1-08
[Acceleration/Deceleration Time].
Adjust F1-10 [Speed Deviation
Detection Level] and F1-11 [Speed
Deviation Detect DelayTime].
Examine the machine.
Release the holding brake.
Measure the motor line-to-line resistance
and replace the motor if a coil is
disconnected.
