Homing
error
protection
68
An error occurred during homing.
An invalid over-travel inhibit input signal was input.
A parameters necessary for homing operation is not
set or an invalid value is set.
• Check the switch, limit sensor, cable and power
supply connected to the over-travel inhibit input
(CCWL/CWL: CN X5 Pin 19/20) for error.
• Check the parameter settings for homing.
• For details, refer to “Homing Operation” in “Operation
Setting” on page 114.

protection
70
A current position (–2147483647 to 2147483647)
overflowed when 16.Pr51 (wraparound accepted) is
“0”.
Do not give an unsuitable operation command to make
the current position exceed “–2147483647 to
2147483647”.
Especially, pay attention to an incremental operation,
jog operation and home offset operation.

Over-travel inhibit input in an operating direction was
detected in a step operation and jog operation after
homing completes.
Both of CCW over-travel inhibit input (CCWL: CN X5
Pin 19) and CW over-travel inhibit input (CWL: CN X5
Pin 20) were in the OPEN state.
• Check the switch, limit sensor, cable and power
supply connected to the over-travel inhibit input
(CCWL/CWL) for error.
• Check the operation command and the mount of limit
sensor.
• Check that a direction of home offset operation is not
the same as that of over-travel inhibit input.
*Maximum

protection
72
A motor command position exceeded a maximum
travel limit range in a step operation and jog operation
after homing completes.
• Do not give an unsuitable operation command to
make the command position exceed the maximum
travel limit range. Especially, pay attention to an
incremental operation, jog operation and home offset
operation.
• Check a set value of 32.Pr01 (setting of maximum
travel in positive direction) and 32.Pr02 (setting of
maximum travel in negative direction)

No.
Control circuit has malfunctioned due to excess noise
or other causes.
Some error has occurred inside of the driver while
triggering self-diagnosis function of the driver.
• Turn off the power once, then re-enter.
• If error repeats, this might be a failure.
Stop using the products, and replace the motor and
