Function Manual, 11/2012, 6FC5397-1CP10-5BA0
Current control active (V390x 0001.7)
The current control loop for the axis/spindle is closed; the current control function is active.
Lubrication pulse (V390x 1002.0)
The IS "Lubrication pulse" is sent by the NCK and changes status once the axis/spindle has
traveled a greater distance than that set in MD33050 LUBRICATION_DIST (travel distance
for lubrication from PLC)
1.3.2
Signals for digital drives, from axis/spindle
Active drive parameter set A, B, C (V390x 4001.0 to .2)
The drive module sends this checkback to the PLC to indicate which drive parameter set is
currently active. With bit combination A, B, C, eight different drive parameter sets can be
selected by the PLC.
Drive ready (V390x 4001.5)
Checkback signal indicating that the drive is ready. The conditions required for traversing the
axis/spindle are fulfilled.
Integrator for n-controller disabled (V390x 4001.6)
The speed-controller integrator is disabled. The speed controller has thus been switched
from PI to P controller.
Pulse enabled (V390x 4001.7)
The pulse enable for the drive module is available. The axis/spindle can now be traversed.
Motor temperature warning (V390x 4002.0).
The drive module signals to the PLC that the motor temperature has exceeded the warning
threshold. If the motor temperature remains at this level, the drive will be stopped after a
defined time (drive MD) and the pulse enable removed.
Heat sink temperature warning (V390x 4002.1).
The drive module signals to the PLC that the heat sink temperature has exceeded the
warning threshold. The pulse enable will be removed for the drive module in question after
20 seconds.
