Description of I/O Signals

Life warning: Sequence output signal (Reference value 46)
The life of internal main circuit capacitors of the servo amplifier and that of the cooling fan are
calculated and output its signal.
Function
The life of internal main circuit capacitors of the servo amplifier and that of the cooling fan are
calculated and, if either exceeds the rated time, a life warning is turned on.
Use the PC Loader or keypad (En03) to discriminate between the main circuit capacitors and
cooling fan.
Parameter setting
To assign the life warning to a sequence output terminal, specify the corresponding value ("46") to
the output terminal function setting parameter.
MD0: Sequence output signal (Reference value 60)
MD1: Sequence output signal (Reference value 61)
MD2: Sequence output signal (Reference value 62)
MD3: Sequence output signal (Reference value 63)
MD4: Sequence output signal (Reference value 64)
MD5: Sequence output signal (Reference value 65)
MD6: Sequence output signal (Reference value 66)
MD7: Sequence output signal (Reference value 67)
The M code of positioning data currently executed is output.
■ Function
The M code of the positioning data being executed is output.
Unlike JIS B 3614, M00, M02, M30, M98 and M99 are not provided with specific functions but are
general-purpose code outputs. No interlock function is provided at M
ON
and M
OFF
.
The M code is output at M code sequence output terminals 0 to 7 (“60” to “67”).
The M code is a hexadecimal between 00H and FFH.
* The default value of the M code is FF.
In case of RS-485 communications, the code can be acquired through in-process positioning data
read function.
Parameter setting
To assign M codes 0 to 7 to sequence output terminals, enter corresponding value (“60” to “67”) to
the system parameter.
