Signal state 1 or edge
change 0 → 1
If a spindle speed (rpm) or a constant cutting speed (m/min or ft/min) is
programmed, one of the following limits has been exceeded:
● Maximum speed of specified gear stage
● Maximum spindle speed
●
Speed limiting by the interface signal from the PLC
● Progr. spindle speed limiting G26
● Progr. spindle speed limiting for G96
The spindle speed is limited to the maximum value.
Signal state 0 or edge
change 1 → 0
If a spindle speed (rpm) or a constant cutting speed (m / min or ft / min) is
programmed, no limit values were exceeded.
Application The IS "Setpoint speed limited" can be used to determine if the programmed
speed cannot be reached. The PLC user program can identify this state as
not permissible and disable path feed, or it can disable the path feed or the
complete
channel. For
IS "Spindle in setpoint range" processing is executed.

If a spindle speed (rpm) or a constant cutting speed (m/min or ft/min) is
programmed, one of the following limits was fallen below:
●
Minimum speed of the specified gear stage
● Minimum spindle speed
● Speed limiting by the PLC
● Progr. spindle speed limiting G25
● Progr. spindle speed limiting with G96
The spindle speed is limited to the minimum limit value.

Signal state 1 or edge
change 0 → 1
The IS "Spindle in setpoint range" is used to signal whether the programmed
- and if relevant - limited spindle speed is reached.
In the spindle control mode, the speed setpoint (programmed speed + spin‐
dle
override including
limits) is compared with the actual speed. If the actual
speed deviates from the setpoint speed by less than the spindle speed tol‐
erance MD35150, then the IS "Spindle in the setpoint range" is set.
