FOLLOWING SPINDLE IN SYNCHRONOUS MODE
1 signal: Spindle operates as following spindle in synchronous mode.
0 signal: Spindle does not operate as following spindle in synchronous mode.
Notes:
• In the synchronous mode the spindle follows the movements of the leading spindle.
• Special monitoring operations are executed only in the synchronous mode (e.g.
synchronism coarse/fine, emergency retraction).
• Commands to the following spindle are ignored in the synchronous mode.
(except: G201 and G202).
• The signal is also indicated in the relevant setting data bit.
NEW K DEFECTIVE
Ü
1 signal: An error has occurred when calculating the new speed ratio K
following spindle and its leading spindle.
0 signal: No error during calculation.
Notes:
• The signal is of significance only if the calculation of a new speed ratio K
triggered first.
• An alarm is issued at the same time as the signal is set.
• The new speed ratio cannot be activated while this signal is set.
• An error during the calculation indicates that impermissible speed ratio parameters have
been entered in the setting data (e.g. denominator equal to 0, numerator too great,
denominator too small).
