13.2 Programming
Extended Functions
724 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
Examples:
WAITC(S2),
:
WAITC(S2, "Fine"),
:
WAITC(S2, ,S4, "Fine")
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.
13.2.2 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
FS
)
Activation of synchronous operation with a defined angular offset POS
FS
between the
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
FS
: 0 ... 359.999 degrees.
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
FS
) or SPOS when synchronous operation is already
active, the angular offset between LS and FS can be changed.
