9.2.64.3 Phase displacement
Phase displacement for synchronisation via system bus (SYNC TIME)
Code Value Function
C1122 0 ...10.000 μs • 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
to
+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).
9.2.64.4 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 inside the ”time slot”, the SYNC1-STAT is switched to HIGH.

Fig. 9-164 “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”.
