● Communications Error Content: Register Number 003D Hex
10-4-3 Parameter Reading and Writing
The following tables show the SYSDRIVE 3G3MV Inverter parameter classes, instances and
attributes, and the corresponding register numbers. Write and read the various parameters with “1"
as the minimum setting unit. Negative numbers are expressed as two's complements. When param-
eters are written, the settings for parameters that can be written during operation become valid after
the being set in RAM, whereas the settings for parameters that cannot be written during operation,
become valid from the next operation. Send an enter command to save the set data in EEPROM.
Note The 2 register numbers that are different from RS-422/485 communications are indicated by
shading (refer to page 10-39).
■ Function Group 1 (n001 to n049)
Note [ ] values indicate those for 400-V-class Inverters.
