Preconditions
The following conditions must be fulfilled for synchronous clutch-in:
1. The difference between the position of the touch probe sensor and the basic position of the tool
at standstill must be equal or greater than the difference between the basic function and the
starting function of the synchronous range:
[5-27] Example: Distances of the individual positions
[5-28] Characteristics of positions for synchronous clutch-in
2. When bTpReceived or bManualSync are enabled, the resulting clutch-in time must not fall below
the minimum clutch-in time parameterised in C05603.
• The time refers to the reference speed when being reached and is thus reduced proportiona-
tely when the master speed is lower than the reference speed.
If the preconditions mentioned before are not fulfilled, clutch-in does not take place. The bError out-
put is set to TRUE and the cause of error is displayed bit coded in C05609.
