5-4-5 Parameter Constant Reading and Writing
The following tables show the SYSDRIVE 3G3FV-series Inverter parameter constant numbers and the
corresponding register numbers. Write and read the various parameter constants with “1” as the mini-
mum setting unit. Negative numbers are expressed as two’s complement. If the setting unit is in hexade-
cimal, there is no need to convert it.
When writing data in parameter constants, be sure to send an enter command to enable the written
data. Unless the enter command is transmitted, the data will not be enabled and the Inverter may not
start.
