FUNC
DATA
In PID control, an output frequency is adjusted to a feedback value.
Use F 0 1 to set a frequency and H 2 1 to make the feedback value and the refer-
ence value equal.
Option selection
(RS485 RTU communication)
0 : Option inactive
1 : Option active
Always set 0 when the optional RS485 RTU serial communication unit is not used.
If 1 is set, Er 8 occurs.
For explanations of “o01” to “o11”, refer to the instruction manual that comes with the
optional RS485 serial communication unit.
