YASKAWA ELECTRIC SIEP C710617 05F YASKAWA AC Drive GA700 Technical Manual
Causes
The communication protocol is not
compatible.
The value set in H5-09 [CE Detection
Time] is too small for the
communications cycle.
The controller software or hardware is
causing a communication problem.
Causes
The monitor value set in H2-20
[Comparator 1 Monitor Selection] was
in the range of H2-21 [Comparator 1
Lower Limit] and H2-22 [Comparator 1
Upper Limit].
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].
Causes
The drive received a fault reset
command when a Run command was
active.
Causes
The communications cycle of the
controller is not set in the permitted
range of the MECHATROLINK
interface option card.
Causes
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.
The holding brake is stopping the motor. Release the holding brake.
6.5 Minor Faults/Alarms
Possible Solutions
• Examine the values set in H5-xx.
• Examine the settings on the controller side and
correct the difference in communication
conditions.
• Change the controller software settings.
• Increase the value set in H5-09.
Examine the controller and remove the cause of the
problem.
Possible Solutions
Examine the monitor value and remove the cause
of the error.
Possible Solutions
Examine the monitor value and remove the cause
of the error.
Possible Solutions
Turn off the Run command then de-energize and
re-energize the drive.
Possible Solutions
Set the communications cycle of the controller in
the permitted range of the MECHATROLINK
interface option card.
Possible Solutions
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.
