Operation Command Source And Speed Command Source During Communication Operation (Pr. 338, Pr. 339, Pr. 550, Pr. 551) - Mitsubishi Electric FR-A700 Instruction Manual

Parameter
6.22.3 Operation command source and speed command source during
communication operation (Pr. 338, Pr. 339, Pr. 550, Pr. 551)
When the inverter RS-485 terminals or communication option is used, the external operation
command and speed command can be made valid. Also, the control command source in the
PU operation mode can be selected.

The above parameters can be set whenever the communication option is connected. (Refer to
section 6.21.4.)
Pr 550 and Pr. 551 are always write-enabled.
Select the control source of the network operation mode (Pr. 550)
Either the inverter RS-485 terminals or communication option can be specified as the source of
control in network operation mode.
For example, set Pr. 550 to "1" when executing parameter write, start command or frequency
setting from the inverter RS-485 terminals in the network operation mode independently of
whether the communication option is connected or not.
NOTE Since Pr. 550 = 9999 (Automatic recognition of the communication option) in the initial set-
ting, parameter write, start command and frequency setting cannot be executed by commu-
nication using the inverter RS-485 terminals when the communication option is fitted.
(Monitor and parameter read can be performed.)
