Filter time
Since the handwheel pulses on the Ethernet bus are not transferred deterministically,
filtering (smoothing) of the handwheel pulse transfer process may be necessary for highly
dynamic drives. The parameter for the filter time is assigned using the following machine
data:
● MD11354 $MN_HANDWHEEL_FILTER_TIME[< x - 1 >] = <filter time>
The filter time specifies the time it takes for the handwheel pulses transferred to the control
to be sent on to the interpolator for traversing purposes. With a filter time of 0.0 s, the
handwheel pulses are sent on to the interpolator within a single interpolation cycle. This can
result in the relevant axis being traversed jerkily.
The recommended filter time is 0.2 to 0.5 s.
