6.4 Manual Handle Mode
73
Speed
In case of moving by the use of the manual handle the speed of the axis depends upon the
selected increment size and upon the speed of the rotation of the handle. The movement is
started by acceleration and finished by deceleration. The pulse number rotated is always
executed, if parameter 1373 HNDLFEED is 0 therefore, if the selected axis cannot follow the
pulses coming from the manual handle those are buffered and are moved after the rotation has
been stopped. Adjust parameter 1373 HNDLFEED=1 to avoid such undesired pulse buffering.
In this case the division on the handle may differ from the movement actually done.
L Note:
The above discussed case is the basic case of manual handle mode. By different machines
functions contrary to these may be created by the machine tool builder. If, for example, an
external manual handle is equipped, the increment and direction selection may be done with
the help of a dial. For details turn to the machine tool builder for an information material.
