4 Function
Setting Error
The function that was set does not support
the communications cycle.
• The electronic gear object ratio was not
1:1 when the communications cycle was
set to 250/500 µs.
• Fully-closed Control Mode was selected
when the communications cycle was set to
250 µs.
• Homing mode (hm) was set in Modes of
operation (6060 hex) when the
communications cycle was set to 250 or
500 µs.
• A mapping exceeding 20 bytes was set in
an RxPDO when the communications
cycle was set to 250 µs.
• A mapping exceeding 12 bytes was set in
an RxPDO during Fully-closed Control
Mode.
• Profile position mode (pp) or Homing
mode (hm) was set in Modes of operation
(6060 hex) when the communications
cycle was set to 1 ms, Fully-closed Control
Mode was selected, and the electronic
gear object ratio was not 1:1.
• The number of bytes (objects) mapped to
RxPDO is 0.
• 11 or more objects were mapped to
RxPDO.
• 12 or more objects were mapped to
TxPDO.
• Reference Position for CSP (4020 hex)
was mapped to TxPDO when the
communications cycle was set to 250/
500 µs or when the electronic gear object
ratio was not 1:1.
• Check the communications cycle settings
or the electronic gear object.
• Check the communications cycle settings
or control mode settings.
• Check the communications cycle settings
or the mode of operation.
• Check the communications cycle settings
or the number of bytes of mapping.
• Check the number of bytes of mapping or
the parameters for the control mode
settings.
• Check the number of mapped objects.
• Check the mapped objects.
95 0 to 4 Motor
mismatch
The Servomotor does not match the Servo
Drive.
Replace the Servomotor with a Servomotor
that matches the Servo Drive.
99 0 Other errors • An error signal was detected due to
excess noise or some other problem.
• An error was reset when safety input 1 or 2
was not in a normal state (one of the input
photocouplers is not ON).
• Turn OFF the power once, and turn it ON
again.
• If the error is displayed even after the
power is turned ON again, the system may
be faulty. Stop using the system, and
replace the Servomotor and/or the Servo
Drive. Return the Servo Drive to the dealer
that it was purchased from and ask for
investigation and repair.
• Reset the error when both safety input 1
and 2 are in a normal state (the both input
photocouplers are ON).
Other
numbers
The control circuit malfunctioned due to
excess noise or some other problem. The
self-diagnosis function of the Servo Drive
was activated, and an error occurred in the
Servo Drive.
• Turn OFF the power once, and turn it ON
again.
• If the error is displayed even after the
power is turned ON again, the system may
be faulty. Stop using the system, and
replace the Servomotor and/or the Servo
Drive. Return the Servo Drive to the dealer
that it was purchased from and ask for
investigation and repair.
