Remark
Index of command is comprised by the group No. of parameters, and HEX number of Parameter No.
For example:
If parameters of F1.11 is to be read, then Index of command=010B;
If parameters of F9.16 is to be read, then Index of command=0910;
If parameters of FF.01 is to be read, then Index of command=0F01;
If parameters of FP.02 is to be read, then Index of command=1302;

Set parameters (Group No.

Index No.)
All the parameters of EV2000 series drives except the parameters whose property is ‘*’ and FP.02~FP.04 can be set.

Appendix 1
.
When setting the parameters, each value must be valid, e.g., when setting F9.00, “Operation data” in the
communication frame should be ASCII code, e.g. 0000, 0666 or 0543 is correct, while 0127 or 1000 is incorrect.
Otherwise, the result will be wrong. Please read the parameters carefully and determine its range before using.
“User’s password” should be input before setting the parameters.
