Pulse enable.
Signal(s) to drive (PLC → NCK)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 Pulse enable is signaled by the PLC for this drive (axis / spindle). The
pulses are only enabled if the drive signals IS:
DB390x DBX4001.5 (drive ready)
using a 1 signal.
In this case, the interface signal:
DB390x DBX4001.7 (pulses enabled) is signaled to the PLC
with a 1 signal.
Signal state 0 The pulses are disabled by the PLC for this drive.
Application Signal-oriented signal.
Special cases, errors, ... If pulse enable is withdrawn for a moving axis / spindle the axis / spindle is
not longer braked in a controlled fashion. The axis / spindle coasts down.
corresponding to ... DB390x DBX4001.7 (pulses enabled)

Spindle / no axis
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: Yes Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
The machine axis is operated as spindle in the following spindle modes:
• Control mode
• Oscillation mode
• Positioning mode
• Rigid tapping
The IS's to the axis (DB380x DBX1000 to DB380x DBX1003) and from the
axis (DB390x DBX1000 to DB390x DBX1003) are invalid.
The IS's to the spindle (DB380x DBX2000 to DB380x DBX2003) and from
the spindle (DB380x DBX2000 to DB380x DBX2003) are valid.
