A0 00 Overload
Warning
The load ratio of Servo
Drive or motor (4150-81
hex) exceeded the level
set in the Overload -
Warning Notification
Level.
Operation was contin-
ued for a long time with
high load.
Perform the following corrections
accordingly.
• Increase the set value of the
acceleration/deceleration time or
the stop time.
• Lighten the load.
• Adjust the gain and inertia ratio.
• If torque waveforms oscillate
excessively, adjust the system by
the tuning so that the oscillation
does not occur.
• Set the appropriate brake timing.
• Increase the capacities of the
Servo Drive and the motor.
There is incorrect wir-
ing of the motor cable or
a broken cable.
• Connect the motor cable as
shown in the wiring diagram. If
the cable is broken, replace it. Or,
connect the motor cable and
encoder cable that are used
together to the same motor.
• Measure the voltage at the brake
terminal. If the brake is applied,
release it.
Increase in friction Check machine conditions and
remove the cause of the friction.
A1 00 Regenera-
tion Over-
load Warning
The Regeneration Load
Ratio (4310-81 hex)
exceeded 85% of the
regeneration overload
ratio.
The regeneration pro-
cessing is set inappro-
priately.
Check the regeneration processing
setting, and set the same value as
the resistance value of the Regen-
eration Resistor in use.
The Regeneration
Resistor is selected
inappropriately.
Check the operation pattern by the
velocity monitor. Check the load
ratio of Regeneration Resistor, and
perform the following corrections
accordingly.
• Increase the deceleration time
and stopping time.
• Decrease the command velocity
to the motor.
• Use an External Regeneration
Resistor.
• Increase the capacities of the
Servo Drive and the motor.
This Regeneration
Resistor is used for con-
tinuous regenerative
braking.
The Regeneration Resistor cannot
be used for continuous regenera-
tive braking.
The applied power sup-
ply voltage is higher
than the specified value.
Apply the specified power supply
voltage.
Regeneration Resistor
failure
Check whether the Regeneration
Resistor is faulty, and use one with-
out failures.
Error No.
