4.8 Axis / spindle-specific signals
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.

Setpoint speed increased (programmed speed too low)
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: Yes Signal(s) updated: Cyclic
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 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 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 fallen below.
Application The IS "Setpoint speed increased" can be used to detect that 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.

Spindle in setpoint range
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: Yes Signal(s) updated: Cyclic
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 +
spindle override including limits) is compared with the actual speed. If the
actual speed deviates from the setpoint speed by less than the spindle
speed tolerance MD35150, then the IS "Spindle in the setpoint range" is set.
Signal state 0 or edge
change 1 → 0
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.
Signal irrelevant for ... all spindle modes except for speed mode (control mode).
