Torque Reference
A series of three filter time constants, 1st-
Filter
order, 2nd-order, and 1st-order, can be set
in order for the torque reference.

Description
A constant acceleration/deceleration is
achieved for smoother operation. The
operation time is increased for the speci-
fied time.
Enables smooth operation.
The reference time increases by the filter
delay time even after the reference input
has been completed.
Enables smooth operation.
The reference time increases by the filter
delay time even after the reference input
has been completed.
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.
These filters are effective in essentially
all frequency bands.
The response is delayed if a large value
(low frequency) is set.
Mainly effective for vibration between
500 and 2,000 Hz.
Instability will result if the setting is not
correct.
