indicates simple mode parameters and indicates extended parameters. When setting parameters, refer to the instruction manual (applied) and understand instructions. Pr. Pr.
The time constant of the primary delay filter relative to external
frequency command (analog input (terminal 1, 2, 4) signal) can
be set.
Valid for eliminating noise of 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 10ms to 1s with the setting of 0 to 8.)
You can select the reset input acceptance, disconnected PU
(FR-DU07) connector detection function and PU stop function.
Reset selection
⋅ You can select the operation timing of reset function (RES
signal, reset command through communication) input
Disconnected PU detection
⋅ This function detects that the PU (FR-DU07/FR-PU04) has
been disconnected from the inverter for longer than 1s and
causes the inverter to provide an alarm output (E.PUE) and
come to an alarm stop.
PU stop selection
⋅ In any of the PU operation, external operation and network
operation modes, the motor can be stopped by pressing of
the PU.
At alarm occurrence, its description can be output as a 4-bit
digital signal from the open collector output terminals.
The alarm code can be read by a programmable controller, etc.,
and its corrective action can be shown on a display, etc.
The following table indicates alarm codes to be output. (0: output
transistor off, 1: output transistor on)
You can select whether write to various parameters can be
performed or not. Use this function to prevent parameter values
from being rewritten by misoperation.
This function can prevent reverse rotation fault resulting from the
incorrect input of the start signal.
