Block change behavior NOC, FINE, COARSE, IPOSTOP
The following options can be selected during definition of the coupling to determine when the
block change takes place:
"NOC" immediate (default)
"FINE" for "fine synchronism"
"COARSE" for "coarse synchronism"
"IPOSTOP" for IPOSTOP (i.e., after setpoint-based synchronism)
The block change response can be specified simply by writing the letters in bold print.
Type of coupling DV, AV
Options:
"DV" setpoint coupling between FS and LS (default)
"AV" actual value coupling between FS and LS
Caution
The coupling type may be changed only when the coupling is deactivated!
Activate synchronized mode COUPON, POS
• Fastest possible activation of coupling with any angle reference between LS and FS:
• Activation with angular offset POS
Position the following spindle
When the synchronized spindle coupling is active, following spindles can also be positioned
within the ±180° range independently of the motion initiated by the master spindle.
