 RSTEF is a drive reset instruction for the VFD-A series drive.

S1
Communication address: K00000 to K0031.

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 D1089. If n=2, PLC will not receive any data.
 Communication example:
1. Connect RS-485 communication between the Delta VFD-S and
PLC.
2. Preset the following VFD-S series parameters.

4. After the PLC executes a RUN command, input point X00 remains ON,
and the input point X01 changes from OFF to ON, PLC will transfer the
command MODRD K1 M2101 to the VFD-S series AC drive, and the
data will be saved in D1089 to D1095.
5. When PLC receives feedback data, the data will be placed in
D1070 to D1076, the ASCII codes will be converted into HEX, and
saved in D1050~D1055. Refer to the following example
