Programming the Angle
The setting of function EC determines the angle between the positions of the master spindle and slave spindle during
synchronisation. BE position = +/- (BM position + EC). EC is programmed in degrees.
Selecting the Type of Synchronisation
If the spindles are not servoed in position when synchronisation is requested, synchronisation is performed according
to the principle described herein. Otherwise, servoed spindle synchronisation with automatic gain control is used.
Master Spindle Acceleration Parameters
The parameters concerning acceleration of the master spindle must be set before requesting synchronisation:
E90330+BM Max. acceleration in deg/s2. If not specified, the setting of parameter P32 is used as default
E90370+BM Nbase Maximum speed at maximum torque in rpm
E90380+BM Nmax Maximum speed at maximum power in rpm
E90360+BM If > 0, enabling of acceleration = f(N)
It should be noted that if BE has a lower dynamic range than BM, the characteristics of BE must be used, or else BE
will not be able to follow BM during accelerations.
Slave Spindle Servoing Parameters
The following parameters concerning the slave spindle must be set before requesting synchronisation:
E90320+BE Position loop gain K0 in rpm/rev
E90370+BE Maximum speed for Tbv(N)=Tbv0 (E90370 = Nbase) E90380+BE Maximum speed N2 for calculation of Tbv(N) (E90380 = Nmax)
E90360+BE Boost factor F
E98024+BE Integral action time constant in ms
Enabling and Disabling Integral Action
Integral action is used to cancel the static error. It must be active during the synchronisation phase. When the two
spindles are mechanically linked (e.g. during part off), integral action must mandatorily be frozen at the value it had at
the time of mechanical linkage.
E98024+BE = 0 No integral action
E98024+BE > 0 Integral action with Ti = E98024+BE (in ms)
E98024+BE < 0 Integral action frozen
