S2
ACdrive master frequency setting for VFD-A series: setting of
K0000 to K4000 represents 0.0Hz to 400.0Hz. For H series AC drive,
the setting of K0000 to K1500 represent 0Hz to 1500Hz.

n
command object, n=1 is for one drive. n=2 communicates to all
drives connected.
 The feedback data from perpherial equipment will be saved in D1070
to D1080. PLC will check the data after the SAVE function is complete.
If there is an error, M1142 will be ON.
