Run Rev
Reverse rotation signal (0:reverse rotation off 1:reverse rotation on)
Reset request at an error occurrence
Valid only at in inverter trip
(0:no function 1:fault reset request)
Request permission bit of control related signals (Bit 0 to Bit 2)
NetCtrl
0: Control related signals are invalid (It will not function even if bit is set.)
1: Control related signals are valid (It will not be reflected to Pr. 338.)
Request permission bit of speed reference (Byte 2, Byte 3)
NetRef
0: Speed setting value (Byte 2, 3) is invalid (It will not function even if a value is set.)
1: Speed setting value (Byte 2, 3) is valid (It will not refflected to Pr. 339.)
Request permission bit of speed reference or parameter write (Byte 2, Byte 3)
0: Byte 2, 3 are speed reference
1: Byte 2, 3 are written to parameter write data (It is written to parameter class and
attribute set with Byte 4, 5.)
Parameter
Instance No. can be specified.
When 00 is specified, instance No. is regarded as 1.
Speed reference (r/min) or parameter write data
Selection conditions are determined according
to a combination of "NetRef (Bit 6)" and
Speed Ref
"WriteParam (Bit 7)".
[When speed reference is selected]
Conversion of speed and frequency depends on
the Pr. 144 settting.
Parameter
