Pn305
Pn306
Converts a stepwise speed reference to a
constant acceleration or deceleration for
the specified time interval.
A constant acceleration/deceleration is
achieved for smoother operation. The
operation time is increased for the speci-
fied time.

Pn204
Pn207
A 1st-order delay filter for the position
reference input.
Enables smooth operation.
The reference time increases by the filter
delay time even after the reference input
has been completed.

Pn207
Pn208
A movement averaging filter for the posi-
tion reference input.
Enables smooth operation.
The reference time increases by the filter
delay time even after the reference input
has been completed.

Pn308
A standard 1st-order delay filter for the
speed feedback.
The feedback speed is smoother.
The response is delayed if a large value is
set.

The speed reference is smoother.
The response is delayed if a large value is
set.

Pn401
A 1st-order delay filter for the force refer-
ence.
This filter is effective in essentially all
frequency bands.
The response is delayed if a large value
(low frequency) is set.

Pn409
Pn40B*
Notch filters can be set for the force refer-
ence.
Mainly effective for vibration between
500 and 2,000 Hz.
Instability will result if the setting is not
correct.
