9.2.28.3 Synchronising to zero track or touch probe
The synchronisation is selected under C0532.
z C0532 = 1, index pulse
– zero track of digital frequency input X9 and zero track by the feedback system set under
C0490 (not for resolver evaluation).
z C0532 = 2, touch probe
– via terminals X5/E4 (actual pulse) and X5/E5 (set pulse).
Touch probe initiators can have delay times which cause a speed-dependent phase offset.
z Set correction value for the phase offset under C0429.
z Formula for correction value at C0429:
Correction value at C0429 = 16384 × correction value
z
Please take the values from the data sheet of the initiator or contact the manufacturer.
Stop!
When the synchronisation via the terminals X5/E4 and X5/E5 (C0532 = 2) is activated, no further
control signals must be taken from these terminals. Changing the configuration via C0005 assigns
the terminals with a basic setting.
Synchronisation mode
For the synchronisation, different modes are available which can be set under C0534.
C0534 Synchronisation mode Note
0 Inactive Function inactive
1 Continuous synchronisation with correction in the shortest
possible way
2 Continuous synchronisation with correction in the shortest
possible way
After a LOW-HIGH edge at DFSET-0-pulse, the zero pulse is
synchronised once
10 One-time synchronisation, a phase deviation is corrected in the
shortest possible way
After a LOW-HIGH edge at DFSET-0-pulse, the zero pulse is
synchronised once
11 One-time synchronisation, a phase deviation is corrected in CW
direction
After a LOW-HIGH edge at DFSET-0-pulse, the zero pulse is
synchronised once
12 One-time synchronisation, a phase deviation is corrected in CCW
direction
After a LOW-HIGH edge at DFSET-0-pulse, the zero pulse is
synchronised once
13 One-time synchronisation, a phase difference is determined
between setpoint pulse and actual pulse and is corrected to the
corresponding direction of rotation according to the sign
After a LOW-HIGH edge at DFSET-0-pulse, the zero pulse is
synchronised once
