406
Flash busy reset timeout
Error erasing/writing the flash ROM
407
Control constant table management information mismatch
error
The management information regarding the control constant table is invalid. If this error
occurs when the controller is started, the control constant table may need to be
updated.
408
Control constant table ID error
The control constant table ID is invalid.
409
Encoder control constant error (power-source voltage
control)
An encoder control constant relating to power-source voltage control is invalid. The
encoder power-source voltage cannot be adjusted (the encoder power will be supplied
without voltage adjustment).
40A
Encoder power-source voltage calculation error
The encoder power-source voltage cannot be adjusted (the encoder power will be
supplied without voltage adjustment). Check the “motor/encoder configuration
information” in driver parameter No. 26 and encoder parameter No. 11.
40B
Speed control parameter calculation error
Check driver parameter Nos. 38, 39, 40, 43, 44, 45, etc.
420
Steady-state (non-push) torque limit over error
The steady-state (non-push) torque limit was exceeded. An unexpected load, locked
operation, etc., may be the cause.
41B
ABS unit encoder error (1)
Causes
[1] The power was reconnected after completion of an absolute reset.
[2] An absolute reset was performed.
Axis movement was detected due to an external factor, etc., while the controller was
communicating with the simple absolute unit. The actuator may have moved due to the
reactive force of the self-standing cable or other external force, or vibration may have
generated at the installation location.
Actions
[1] Turn off the power and then reconnect the power in a condition where the actuator
is not receiving vibration.
(Info. 1 in the error list is “1”)
[2] Perform an absolute reset in a condition where the actuator is not receiving
vibration.
(Info. 1 in the error list is “2”)
