Synchronisation via touch probe at CCTRL2−TPIN. 2
The input CCTRL2−TPIN is suitable for a one−time synchronisation and sets the position of the drive
in standstill.
Procedure:
1. Set CCTRL2−TPIN/E4 = LOW.
2. Define the position of the touch probe sensor on the machine at CCTRL2−TP−POS.
3. A LOW−HIGH edge at CCTRL2−TPIN synchronises the drive to the set position which is output
at CCTRL2−PHI−SET.

l If a parameter set is downloaded, C1367/1 is not transferred, as for each
commissioning the actual, current position of the tool to the machine zero point
has to be entered in the code. The position of the actual value encoder (multi−turn
absolute value encoder) depends on the rotor position when the motor is
mounted to the machine, and on the actual position of the tool. A new setting
therefore is required as soon as a drive component is not tied positively anymore.
l If the feedback system is switched over, also the machine zero point has to be
re−entered (the synchronisation always is effected via the feedback system and is
specifically adapted to it).
The function Set reference" only has to be carried out once:
1. Enter the current distance [s−units] of the tool to the machine zero point in C1367/1 (set
reference).
2. Switch the controller off and then on again, in order to reinitialise the profile data.
– After every mains connection, the controller automatically determines the current distance to
the machine zero point, which is output at CCTRL2−PHI−SET2 (C1339/2) and
CCTRL2−PHI−ACT (C1339/3).
– The profile position is output at CCTRL2−PHI−SET after mains connection.
3. Where required, position the drive to the profile via the RFGPH2 function block.
