3.5.30.3 Synchronising to zero track or touch probe
(
Stop!
When the synchronisation via terminals X5/E4 and X5/E5 (C0532 = 2) is activated,
these terminals must not contain any other signal connections. If a basic
configuration is selected via C0005, the terminals receive a basic setting.
Synchronisation is selected in C0532.
l 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).
l C0532 = 2, touch probe
– Via terminals X5/E4 (actual pulse) and X5/E5 (set pulse).
)
Note!
For both modes you can define a dividing factor for the actual pulses in C0531 and
for the set pulses in C0535.
l For C0531 = 10, for example, only every 10. actual pulse is evaluated. The other 9
pulses are ignored.
l Lenze setting: C0531 = 1, C0535 = 1
Correction of the touch probe initiator (terminal X5/E5)
Delay times when activating the initiator cause a speed−dependent angular offset (e.g. in the case
of positioning, synchronising). In order to take this angular offset into account, the response time [ms]
of the initiators as a function of the setpoint speed is converted to a phase angle correction and is
then taken into consideration in the setpoint angle.
How to determine the phase angle correction value:
1. Convert the response time [ms] to a correction value [inc] using the formula:
Phase angle correction value in C0429 = 16384 × response time [ms]
– The response time [ms] can be gathered from the data sheet or requested from the
manufacturer of the initiator.
2. Set the phase angle correction value for the angular offset in C0429.
