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 filter time is parameterized using the following machine data:
● MD11354 $MN_HANDWHEEL_FILTER_TIME[< x - 1 >] = <filter time>
with x = 1, 2, 3, ... (handwheel number in the NC) and filter time = 0.0 ... 2.0 s
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 jerky
axis traversing.
The recommended filter time is: 0.2 – 0.5 s
Zero speed detection
A stationary state is detected by the Ethernet modules to which the handwheel is connected.
If a handwheel does not transfer any handwheel pulses for a defined period of time, the module
detects this to be a stationary state and transfers it to the NC/PLC interface:
