S3: Synchronous spindle
13.2 Programming
Extended Functions
720 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
Threshold values
The relevant position or velocity tolerance range for the following spindle in relation to the
leading spindle must be specified in degrees or 1 rev/min.
● Threshold value for "Coarse synchronism"
axis spec. MD37200: AV, DV: COUPLE_POS_TOL_COARSE
MD37220: VV: COUPLE_VELO_TOL_COARSE
● Threshold value for "Fine synchronism"
axis spec. MD37210: AV,DV: COUPLE_POS_TOL_FINE
MD37230: VV: COUPLE_VELO_TOL_FINE
Speed/acceleration limits
In synchronous mode, the speed and acceleration limit values of the leading spindle are
adjusted internally in the control in such a way that the following spindle can imitate its
movement, allowing for the currently selected gear stage and effective speed ratio, without
violating its own limit values.
For example, the LS is automatically decelerated to prevent the FS from exceeding the
maximum speed in order to maintain synchronism between the spindles.
