FL REMOTE COMMUNICATION FUNCTION
Operation mode setting
4.5.2 PU operation interlock
The PU operation interlock function is designed to forcibly change the operation mode to the Network operation mode
when the PU operation interlock signal (X12) input turns OFF.
This function prevents the operation mode from being accidentally unswitched from the PU operation mode. If the
operation mode is left unswitched from the PU operation mode, the inverter does not reply to the commands sent through
FL remote communication.
<Function/operation changed by switching ON-OFF the X12 signal>
4.5.3 Operation availability in each operation mode
Operation availability in each operation mode is shown below.
(Monitoring and parameter read can be performed from any operation regardless of operation mode.)
∗1 Some parameters may be write-disabled according to the Pr. 77 Parameter write selection setting and operating status. (Refer to page 166)
∗2 Some parameters are write-enabled independently of the operation mode and command source presence/absence. When Pr. 77 = 2, write is enabled.
(Refer to the parameter list on page 78) Parameter clear is disabled.
∗3 Enabled only when stopped by the PU. At a PU stop, PS is displayed on the operation panel. As set in Pr. 75 Reset selection/PU stop selection. (Refer to page 165)

∗1 The operation mode switches to the Network operation mode independently of whether the start signal (STF, STR) is ON or OFF. Therefore, the
motor is run in Network operation mode when the X12 signal is turned OFF with either of STF and STR ON.
∗2 At fault occurrence, pressing of the operation panel resets the inverter.
NOTE
If the X12 signal is ON, the operation mode cannot be switched to the PU operation mode when the start signal (STF,
STR) is ON.
