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.
