Application The path feed must generally be disabled when the spindle is in the
acceleration phase (programmed speed setpoint not yet reached).
This can be done in the following way:
• The IS "Spindle in the setpoint range" is evaluated and the IS "Feedrate
disable" (DB3200 DBX6.0) is set.
• MD35500 is set and the NCK evaluates internally as to whether the
spindle is in the setpoint range. The path feed is only enabled if the
spindle is within the setpoint range. Positioning axes are never stopped
by this function.
corresponding to ... MD35150 SPIND_DES_VELO_TOL (spindle speed tolerance)
MD35500 SPIND_ON_SPEED_AT_IPO_START
(feedrate enable with spindle in the setpoint range)

Actual direction of rotation clockwise
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: Yes Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
If the spindle is rotating, the CLOCKWISE direction of rotation is signaled
using IS "Actual direction or rotation, clockwise" = 1. The actual direction of
rotation is derived from the spindle position measuring encoder.
Signal state 0 or edge
change 1 → 0
If the spindle is rotating, then the COUNTER-CLOCKWISE direction of
rotation is signaled using IS "Actual direction or rotation, clockwise" = 0.
Signal irrelevant for ...
• Spindle stationary, IS "Axis / spindle stationary" = 1(at standstill it is not
possible to evaluate a direction of rotation)
• Spindles without position measuring encoder
corresponding to ... IS "Spindle stationary" (DB390x DBX1.4)

The spindle is in the oscillation mode if a new gear stage was defined using
the automatic gear stage selection (M40) or using M41 to M45 (IS "Change
gear stage" is set). The IS "Change gear stage" is only set if a new gear
stage is defined that is not the same as the actual gear stage.
