Causes
[When in Trouble]
Measures
Remove the causes of the error, then shut off the
power to reset.
• 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.
Check the settings of positioning parameter and step para-
meter. For details, refer to "Step Operation" in "Operation
Setting" on page 107 and "Jog Operation" on page 112.
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.
• 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.
• 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)
Check the setting of the rotary switch on the front
panel.
Replace it with a supported external scale.
Replace the motor which matches to 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
the driver. Return the products to the dealer or
manufacturer.
