4.2.29 Input filter time constant (Pr. 74)
Pr. 74 "filter time constant"
You can set the input section's internal filter constant for an external voltage or current
frequency setting signal.
!
Effective for eliminating noise in the frequency setting circuit.
!
Increase the filter time constant if steady operation cannot be performed due to
noise. A larger setting results in slower response. (The time constant can be set
between approximately 1ms to 1s with the setting of 0 to 8. A larger setting results in
a larger filter time constant.)

4.2.30 Reset selection/disconnected PU detection/PU stop
selection (Pr. 75)
Pr. 75 "reset selection/disconnected PU detection/PU stop selection"
You can select the reset input acceptance, control panel (FR-PA02-
02
) or PU (FR-
PU04) connector disconnection detection function and PU stop function.
!
Reset selection :You can select the reset function input timing.
!
PU disconnection detection :When it is detected that the control panel
(FR-PA02
-02)
/PU(FR-PU04) is disconnected from the
inverter for more than 1 second, the inverter outputs an
alarm code (E.PUE) and comes to an alarm stop.
!
PU stop selection : When an alarm occurs in any operation mode, you can
stop the inverter from the PU by pressing the
STOP
RESET
key.
