Target situation

SlaveMaster

Dö=0

Dö = phase offset

n = Speed

Fig. 2−4 Target situation for zero pulse processing (Döā+ā0)

Conditions for reaching the target situation:

l The function must be activated via code C0534 (function block DFSET)

l The input DFSET−0−PULSE must be triggered with a HIGH signal when the zero pulse is

evaluated once (function block DFSET)

l The angle control must be activated (function block MCTRL)

l The zero pulses must be connected to the Sub−D connectors X9 and X8 (X8 when using an

encoder)

Zero pulse at the setpoint

The set rotor position is specified via the setpoint zero pulse (i.e. when the drive system is running).

It is only synchronised if one setpoint zero pulse and actual zero pulse have occurred before, i.e. not

before the second zero pulse.

Control mode:

The phase offset is compensated via acceleration or deceleration. The direction (acceleration or

deceleration) depends on the detected phase offset. If the rotor is leading in the range from 0 to 180 °,

the drive is synchronised by deceleration. If the rotor is lagging in the range from 0 to 180 °, the drive

is synchronised by acceleration.

Different synchronisation modes

In C0534 you can select between different synchronisation modes.

C0534 Synchronisation mode

1 Continuous synchronisation as described under "Zero pulse at the setpoint" (see page 2−28)

2 Same as selection 1, but DFSET−0−PULSE must be triggered with a LOW−HIGH edge

10 One−time synchronisation; control mode as described under "Zero pulse at the setpoint" (see page 2−28)

11 One−time synchronisation; the drive is always synchronised by clockwise rotation

12 One−time synchronisation; the drive is always synchronised by counter−clockwise rotation

13 One−time evaluation of the setpoint pulse and the actual pulse; the synchronisation direction results from the sign between

setpoint pulse and actual pulse
