The IS "Spindle in setpoint range" signals whether the spindle is accelerating
or braking.
In the spindle control mode, the speed setpoint (programmed speed * spindle
override including limits) is compared with the actual speed. If the actual
speed deviates from the setpoint speed by more than the spindle speed
tolerance MD35150, then the IS "Spindle in the setpoint range" is reset.
all spindle modes except for speed mode (control mode).
The path feed must generally be disabled when the spindle is in the accel‐
eration 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.

Actual direction of rotation clockwise
Signal(s) from axis / spindle (NCK → PLC)
Signal(s) updated: Cyclic
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.
If the spindle is rotating, then the COUNTER-CLOCKWISE direction of rota‐
tion is signaled using IS "Actual direction or rotation, clockwise" = 0.
● Spindle stationary, IS "Axis / spindle stationary" = 1(at standstill it is not
possible to evaluate a direction of rotation)
● Spindles without position measuring encoder
IS "Spindle stationary" (DB390x DBX1.4)

Active spindle positioning mode
Signal(s) from axis / spindle (NCK → PLC)
Signal(s) updated: Cyclic
When programming SPOS=... the spindle is in positioning mode.
