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.
If a spindle speed (rpm) or a constant cutting speed (m / min or ft / min) is
programmed, no limit values were exceeded.
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.
If a spindle speed (rpm) or a constant cutting speed (m / min or ft / min) is
programmed, no limit values were fallen below.
The IS "Setpoint speed increased" can be used to detect that the program‐
med 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 exe‐
cuted.

Spindle in setpoint range
Signal(s) from axis / spindle (NCK → PLC)
Signal(s) updated: Cyclic
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.
