C7510 Error message Battery voltage low (R/C)
Cause The battery will be spent soon.
Measures Replace the battery of controller. For more information about the replacement procedure, refer to the
separate volumes, "Controller setup, basic operation, and maintenance.".
C7520 Error message Battery consumption time is over
Cause The battery consumption time was exceeded
Measures Replace the batteries of both the robot arm and controller. For more information about the replacement
procedure, refer to the separate volumes, "Instruction Manual/Robot Arm Setup to Maintenance" and
"Controller setup, basic operation, and maintenance."
C753n
(n indicates the
axis number (1
to 6).)
Error message Replenishment time of grease
Cause It seems that grease reached longevity
Measures Replenish grease
C754n
(n indicates the
axis number (1
to 6).)
Error message Exchange time of the belt
Cause It seems that the belt reached longevity
Measures Execute the check and the exchange of the belt
H7600 * Error message Mechanism number of additional axis is illegal.
Cause The value of AXMENO (mechanism No. used) parameter is illegal.
Measures On the mechanical additional axis, change "0" to a value which is smaller than set to AXUNUM (number of
mechanisms used).
H7601 * Error message Axis number of additional axis is illegal.
Cause The value of AXJNO (setting axis No.) is illegal.
Measures Change the value of this parameter from 1 to 3.
Change the value of this parameter to a order from 1.
H7602 * Error message Axis numbers of additional axis are overlap.
Cause As the parameter value of AXJNO (setting axis No.), the same value is set at two or more elements.
Measures Change the values of the element Nos. which set the same values at this pa-rameter AXMENO, to all
different values.
H7603 * Error message Unit of additional axis is illegal.
Cause The value of AXUNT (unit axis) parameter is illegal.
Measures Change the values of all elements of this parameter to "0" or "1".
H7604 * Error message Acceleration time of additional axis is illegal.
Cause The value of AXACC (acceleration time) parameter is illegal.
Measures Change the values of all elements of this parameter to positive real numbers.
H7605 * Error message Deceleration time of additional axis is illegal.
Cause The value of AXDEC (deceleration time) parameter is illegal.
Measures Change the values of all elements of this parameter to positive real numbers.
H7606 * Error message Gear ratio numerator of additional axis is illegal.
Cause The value of AXGRTN (total speed ratio numerator) parameter is illegal.
Measures Change the values of all elements of this parameter to positive integers.
H7607 * Error message Gear ratio denominator of additional axis is illegal.
Cause The value of AXGRTD (total speed ratio denominator) parameter is illegal.
Measures Change the values of all elements of this parameter to positive integers.
H7609 * Error message Motor rated speed of additional axis is illegal.
Cause The value of AXMREV (rated speed) parameter is illegal.
Measures Change the values of all elements of this parameter to positive integers.
H7610 * Error message Motor maximum speed of additional axis is illegal.
Cause The value of AXJMX (maximum speed) parameter is illegal.
Measures Change the values of all elements of this parameter to positive integers.
H7611 * Error message Encoder pulse of additional axis is illegal.
Cause The value of AXENCR (encoder resolution) parameter is illegal.
Measures Change the values of all elements of this parameter to positive integers.
