Synchronising to zero track or touch probe

(

Stop!

If synchronisation via terminals X5/E4 and X5/E5 (C0532 = 2) is activated, there
must not be any other signal connections to the terminals. If you have selected a
basic configuration via C0005, the terminals are subject to a basic assignment.

The synchronisation mode can be selected in C0532.

l

C0532 = 1, zero pulse

– Zero track of digital frequency input X9 and zero track by the feedback system set under

C0490 (not for resolver evaluation).

l

C0532 = 2, touch probe

– Via terminals X5/E4 (actual pulse) and X5/E5 (setpoint pulse).

l

C0532 = 3, zero pulse (setpoint) and touch probe (actual value)

– Setpoint pulses of digital frequency input X9 and actual pulses via the touch probe input at

terminal X5/E4.

)

Note!

For all three modes you can define a division factor for the actual pulses (code
C0531) and for the setpoint pulses (code C0535).

l

Example: For C0531 = 10 only every tenth actual pulse is evaluated. The other 9
pulses are ignored.

l

Lenze setting: C0531 = 1, C0533 = 3

Correction of the touch probe initiator (terminal X5/E5)

Delay times during the activation of the initiator cause a speed−dependent angular offset (e.g. during
positioning, synchronising). To compensate this angular offset, the response time [ms] of the
initiators is converted into an angular correction value depending on the setpoint speed and then
taken into account in the setpoint angle.

How to determine the angular correction value:

1. Use the below formula to convert the response time [ms] into a correction value [inc]:

Angular correction value in C0429 = 16384 × response time [ms]

– Please refer to the data sheet for the response time [ms] or contact the manufacturer of the

initiator.

2. Set the angular correction value for the angular offset in C0429.
