Switch The Coupling (Coupon, Couponc, Coupof) On And Off - Siemens SINUMERIK 840D sl Function Manual

S3: Synchronous spindle
14.2 Programming
Stop and block change
If "Stop" has been activated for the cancellation period of the axis enables for the leading or
following spindle, then the last setpoint positions with the setting of the axis enables from the
servo drive are approached again.
Commands COUPON and WAITC can influence the block change behavior. The block change
criterion is defined using COUPDEF or via the MD21320
$MC_COUPLE_BLOCK_CHANGE_CTRL_1.
14.2.2

Switch the coupling (COUPON, COUPONC, COUPOF) on and off

Activate synchronous mode
Language command COUPON is used to activate couplings and synchronous mode.
Two methods by which synchronous operation can be activated are available:
1. COUPON(FS, LS)
Fastest possible activation of synchronous operation with any angular reference between
the leading and following spindles.
2. COUPON(FS, LS, POS
Activation of synchronous operation with a defined angular offset POS
leading and following spindles. This offset is referred to the zero degrees position of the
leading spindle in a positive direction of rotation. The block change is enabled according
to the defined setting. Range of POS
3. COUPONC(FS, LS)
When activating with COUPONC, the previous programming of M3 S... or M4 S... is adopted.
A difference in speed is transferred immediately. An offset position cannot be programmed.
By programming COUPON(FS, LS, POS
active, the angular offset between LS and FS can be changed.
Deactivate synchronous mode
Three different methods can be selected to deactivate synchronous mode:
1. COUPOF(FS, LS)
Fastest possible deactivation of synchronous operation. The block change is enabled
immediately.
2. COUPOF(FS, LS, POS
Deselection of synchronous operation after deactivation position POS
Block change is not enabled until this position has been crossed.
3. COUPOF(FS, LS, POS
Deselection of synchronous operation after the two deactivation positions POS
POS
have been crossed.
