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 Turn the power OFF and ON once. When it comes back, contact to the dealer.
H093n *
(n indicates the
axis number (1
to 8).)
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. When it comes back, contact to the dealer.
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."
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.
H096n
(n indicates the
axis number (1
to 8).)
Error message Excessive error 1
Cause The position error exceeded at servo ON.
Measures Check the load weight and press, etc. If the surrounding temperature is low, or starting after stopping
operation for an extended period of time, perform running-in operation at low speed or use the warm-up
operation mode.
H097n
(n indicates the
axis number (1
to 8).)
Error message Excessive error 2
Cause The position error exceeded at servo OFF.
Measures Check the moving robot arm by something power.
H098n
(n indicates the
axis number (1
to 8).)
Error message Excessive error 3
Cause The motor current was not flowing when excessive error 1.
Measures Check the motor connection wire connection.
H101n
(n indicates the
axis number (1
to 8).)
Error message Collision detection
Cause A collision was detected.
Measures Release the collision state.
H102n
(n indicates the
axis number (1
to 8).)
Error message Servo AMP over-regeneration
Cause The additional axis exceeded the regenerative performance limit.
Measures Check the regenerative capacity and parameters for the additional axis.
H1030 * Error message Power supply over-regeneration
Cause The converter's regenerative performance limit was exceeded.
Measures Wait at least 15 minutes in the power ON state, and then turn the power OFF and ON.
H104n *
(n indicates the
axis number (1
to 8).)
Error message Encoder init communication error
Cause An abnormality may have occurred in the position detector cable connection.
Measures Turn the power OFF and ON once. When it comes back, contact to the dealer.
H107n *
(n indicates the
axis number (1
to 8).)
Error message Encoder communication error
Cause Communication with the position detector was cut off.
Measures Turn the power OFF and ON once. When it comes back, contact to the dealer.
H108n *
(n indicates the
axis number (1
to 8).)
Error message Servo AMP communication error
Cause An abnormality may have occurred in the communication cable connection.
Measures Turn the power OFF and ON once. When it comes back, contact to the dealer.
H1090 *
H109n *
(n indicates the
axis number (1
to 8).)
Error message Servo AMP initialization error
Cause An abnormality may have occurred in the servo axis settings (parameters, rotary switches).
Measures Turn the power OFF and ON once. When it comes back, contact to the dealer.
