3.5.62 Multi−axis synchronisation (SYNC1)

3−265

EDSVS9332P−EXT DE 2.0

3.5.62.3 Phase displacement

Phase displacement for synchronisation via system bus (SYNC TIME)

Code Value Function

C1122 0 ...10.000 ms · C1120 = 1

– Phase displacement between the sync telegram and the start of the internal control program.

– The parameters are set automatically depending on the parameter setting of the system bus (CAN).

· C1120 = 2

– C1122 has no effect.

Phase displacement for synchronisation via terminal (PHASESHIFT)

Code Value Function

C1123/1 −1.000 ms

+1.000 ms

· C1120 = 1

– C1123/1 has no effect.

· C1120 = 2

– Phase displacement between the sync signal and the start of the internal control program (e. g. for

compensating the effects of signal propagation delays/dead times for the sync signal of the single

slave drives).

3.5.62.4 Time slot for synchronisation via terminal

Code Value Function

C1123/2 0 ... 1.000 ms · C1120 = 1

– C1123/2 has no effect.

· C1120 = 2

– Definition of a "time slot" for the LOW−HIGH edges of the sync signal for the slave (defined via

C1121/1).

– If the sync signal sent by the master is within the "time slot", the SYNC1−STAT is switched to HIGH.

Fig. 3−211 Time slot" for the LOW−HIGH edges of the sync signal

Tip!

A jitter of up to ±200 μs on the LOW−HIGH edges of the sync signal is permissible. The size of the

jitter affects the parameter setting of the "time slot".
