③ Parameter concerning trace function
'Constant at the time of filtering': Select the size of constant at the time of filtering (F678).
'Trace selection': Select the trace data acquisition timing (F740).
'Trace cycle': Select the trace cycle (F741).
'Trace data1': Select type1 (F742) of data.
'Trace data2': Select type2 (F743) of data.
'Trace data3': Select type3 (F744) of data.
'Trace data4': Select type4 (F745) of data.
*2 Set all trace-related parameters before operating the inverter. If after the inverter did
trip or trigger that it is changed, that data cannot be read.
*3 Take special care when using analog output signals (FM and AM terminals) with the
The constant at the time of filtering (F678) also acts on analog output signals.
Therefore, if there is a probability that these output signals will affect the machine, do
not change the value of constant at the time of filtering.
By default, the constant is set at 64ms.
0:9600bps 1:19200bps 2:38400bps
0:Non parity 1:Even parity 2:Odd parity
