3. Controller Functions
3.3 Main Spindle Speed Signals
The main spindle speed determines the time point of the feed enabling
signal, gear change and clamping of the holding brake.
The requirements are met if signal output „N
act
= N
comml
“, „N < N
min
“ and the
selectable torque disconnect is below N
min
. The signal operating thresholds
can be set as required.

Function conversion
Note:
The display message „N * NCMD“ means N
act
≠ N
comm
. This appears when
the speed is above the minimum speed, but has not yet reached the
command value speed.

PQ-FUNCT
Function
if speed command value and motor speed are under
MIN RPM, then signal output "N < MIN" goes to 1
maximum deviation of speed from command value
within which signal output " N = CMD " goes to 1
signal output " N = CMD " also signals
without RF enabling signal (control input RF = 0)
change of input value of " MAX DEV ";
1 = 0.1% of current Ncommand
torque off if speed is less than
value in MINRPM
independent of speed command value, signal output
"N < MIN" goes to 1 if motor speed less than
MIN RPM (A 03)

Note: When the values of parameter „MAX DEV“ (A04) are input as per
cents of the speed command value, then the smallest deviation is limited
to 10 rpm.
