H0880 *
H088n *
(n indicates the
axis number (1
to 8).)
Error message Power module overheat
Cause Overheating of the power module regenerative resistor was detected.
Measures Turn the controller power OFF, wait a while, and then turn ON again. If it comes back, contact your service
provider.
H089n
(n indicates the
axis number (1
to 8).)
Error message Servo amplifier motor overheat
Cause The position detector's thermal protector activated.
Measures Turn the controller power OFF, wait a while, and then turn ON again. Decrease the acceleration/
deceleration time of the operation speed, for instance.
Refer to "Detailed explanation of command words"/"Accel (Accelerate)," "Ovrd (Override)" and "Spd
(Speed)," or "Detailed explanation of Robot Status Variable"/"M_SetAdl," "M_LdfAct" and "Functions set
with parameters"/"JADL (Optimum acceleration/deceleration adjustment rate)" of the Separate Volume,
"INSTRUCTION MANUAL/Detailed Explanation of Functions and Operations."
H090n *
(n indicates the
axis number (1
to 8).)
Error message Absolute position overspeed
Cause It moved 45 mm/sec or faster with the absolute position linear scale during initialization.
Measures Turn the power OFF and ON once. If it comes back, contact your service provider.
H091n *
(n indicates the
axis number (1
to 8).)
Error message Servo amplifier overspeed
Cause A speed exceeding the motor's tolerable speed was detected.
Measures Turn the power OFF and ON once. If it comes back, contact your service provider.
H0920 *
H092n *
(n indicates the
axis number (1
to 8).)
Error message Power module overcurrent
Cause A servo amplifier or power supply overcurrent was detected. An error was detected in the servo amplifier's
gate circuit. A connection or conductance error may have occurred in the motor cable .
Measures Confirms the connection of the machine cable and the locomotion-axis cable. If it comes back, contact
your service provider.
H093n *
(n indicates the
axis number (1
to 8).)
One of the errors below is detected.
Please take measures corresponding to an error message.
Error message Motor overcurrent
Cause An excessive current flowed to the motor, or the A/D converter output is abnormal. An abnormality may
have occurred in the connection of the motor's power line.
Measures Turn the power OFF and ON once. Confirms the connection of the machine cable and the locomotion-axis
cable etc. If it comes back, contact your service provider.
Error message Motor overcurrent (Grounding)
Cause The motor power cable is in contact with ground
Measures Turn the power OFF and ON once. Confirms the connection of the machine cable and the locomotion-axis
cable etc. If it comes back, contact your service provider.
H094n
(n indicates the
axis number (1
to 8).)
Error message Overload (over weight 1)
Cause Operation tight for a motor (operation with high duty) was performed more than fixed time.
Measures Decrease the acceleration/deceleration time of the operation speed, for instance.
Refer to "Detailed explanation of command words"/"Accel (Accelerate)," "Ovrd (Override)" and "Spd
(Speed)," or "Detailed explanation of Robot Status Variable"/"M_SetAdl," "M_LdfAct" and "Functions set
with parameters"/"JADL (Optimum acceleration/deceleration adjustment rate)" of the Separate Volume,
"INSTRUCTION MANUAL/Detailed Explanation of Functions and Operations."
Confirms that conveyance conditions (hand mass, work-piece mass) are less than specification values.
When it comes back, contact to the dealer.
H095n
(n indicates the
axis number (1
to 8).)
Error message Overload (over weight 2)
Cause The maximum output current continued for more than one second.
Measures Check the load weight and the robot pressing, etc.
Confirms that conveyance conditions (hand mass, work-piece mass) are less than specification values.
When it comes back, contact to the dealer.
