return all zeros
Notes:
1. Desired frequency of 35.75 Hz requires a value of 3575 in register data code 002h. Scaling depends on the setting of o1-03.
2. Effective when H2-01 = 0Fh.
3. Effective when H2-02 = 0Fh.
4. Effective when H2-03 = 0Fh.
5. Effective when H4-01 = 1Fh.
6. Effective when H4-04 = 1Fh.
* Set parameter o2-09 to ‘1’ so that the Modbus Register Address of the Operation Signals register is 01h and the Frequency Reference register is 02h. The
Modbus Register Address for Operation Signals register is 00h and the Frequency Reference is 01h for flash software versions previous to ‘1024’
and CPU version ‘20’.
