Zero−pulse from setpoint:
Set code C0428 (SB DF_IN_DigitalFrequency) to 0.
Tip!
Touch probe initiators can have response delay times that cause a speed−dependent phase−angle
offset.
Code C0429 can be used to set a correction value (−32767 incr. ... 32767 incr.) for this phase−angle
offset.
TouchProbe from actual value:
·
Set code C0911 (SB MCTRL_MotorControl) to 1.
·
The TouchProbe is activated through terminal X5/E4 (actual−value pulse).
Tip!
Touch probe initiators can have response delay times that cause a speed−dependent phase offset.
Code C0910 can be used to set a correction value (−32767 incr. ... 32767 incr.) for this phase−angle
offset.
TouchProbe from setpoint:
·
Set code C0428 (SB DF_IN_DigitalFrequency) to 1.
·
The TouchProbe is activated through terminal X5/E5 (setpoint pulse).
Tip!
Touch probe initiators can have response delay times that cause a speed−dependent phase−angle
offset.
Code C0429 can be used to set a correction value (−32767 incr. ... 32767 incr.) for this phase−angle
offset.
Formula for correction value at C0429 and C0910:
Correction value at C0429/C0910 = 16384 * correction value
·
Please obtain the values from the data sheet of the initiator, or contact the manufacturer.
Stop!
If the synchronization via terminals X5/E4 and X5/E5 (C0532 = 2), make sure that no other control
signals are taken from these terminals.
