Setup mode [819]
You will find detailed information on "Setup mode" in the chapter
entitled "Setup mode" in the Function Description of manual /1/.
Mode 1 "setup" allows the axis to be moved in position control mode
using the direction commands "jog forwards" [J_FWD] and "jog
backwards" [J_BWD].
The "fast/slow" command" [F_S] can be used to switch between two
velocity levels, which can be set in U510.1 and U510.2. The two
velocity levels are multiplied by the override.
In order to prevent abrupt changes in velocity, the output setpoint is
controlled by a ramp-function generator, the ramps of which can be
adjusted with MD18 and MD19.
Software limit switches MD12 and MD13 are evaluated, however this is
only the case with an incremental position encoder if the axis has
already been referenced (status bit [ARFD] = 1). A start command
[STA] is not required for setup mode.
Setup mode is useful for commissioning and maintenance work and
machine setup, for example. Setup mode also includes the teach-in
feature, which allows you to enter the current position in an automatic
NC program block.
The control signal commands for the positive direction of movement are
shown in the diagram below.
