Gain adjustment of position control

Pr.422 Position loop gain
Pr.425 Position feed forward command filter
Make adjustment of Pr.422 when any of such phenomena as
unusual vibration, noise and overcurrent of the motor/machine
occurs.
Increasing the setting improves trackability for the position
command and also improves servo rigidity at a stop, but oppositely
makes an overshoot and vibration more liable to occur.
Function of Pr.423 is designed to cancel a delay caused by the droop
pulses of the deviation counter. Primary delay filter relative to the
feed forward command can be input in Pr.425.

Positioning adjustment parameter

Pr.426 In-position width
When the number of droop pulses has fallen below the value set in
Pr.426, the in-position signal (Y36) turns on.
When droop pulses exceed the value set in Pr.427, position error
large occurs and displays an error (E.OD) to stop the inverter.

Maintenance of parts

Pr.503 Maintenance timer
When the cumulative energization time of the inverter reaches the
parameter set time, the maintenance timer output signal (Y95) is
output. (MT) is displayed on the operation panel (FR-
DU07).
This can be used as a guideline for the maintenance time of
peripheral devices.

Current average value monitor signal
Pr.555 Current average time
Pr.557 Current average value monitor signal output reference current
The average value of the output current during constant speed
operation and the maintenance timer value are output as a pulse to the
current average value monitor signal (Y93).
The pulse width output to the I/O module of the PLC or the like can be
used as a guideline due to abrasion of machines and elongation of belt
and for aged deterioration of devices to know the maintenance time.
The current average value monitor signal (Y93) is output as pulse for
20s as 1 cycle and repeatedly output during constant speed operation.
From acceleration to constant speed operation

When the speed has changed to constant
from acceleration/deceleration, Y93 signal is
not output for Pr.556 time.
2) Start pulse
Output as Hi pulse shape for 1s (fixed)
Time and output current set in Pr.555 are averaged
3) Output current average value pulse
The averaged current value is output as low pulse shape for
0.5 to 9s (10 to 180%) during start bit output.
