9.6 Posion
detecon with touch probe (TP)
A "touch probe" (short: "TP") is an event that can be triggered, for instance via a digital input
in an edge-controlled manner to detect and further process an actual value (which is changing
fast) at the triggering me.

ypical applicaons for touch probes:
•
Homing
•
Mark synchronisaon
•
Length measurements
•
Up to 2 touch probe channels can be used in parallel.
•
Possible touch probe sources:
•
TP1 : Zero pulse posion encoder or digital input DI1
•
TP2 : Z
ero pulse posion encoder or digital input DI2
The digital inputs DI1 and DI2 can be addionally evaluated any me as "nor-
mal" digit
al inputs via .
9.6.1 Default mapping
The default mapping for a touch probe detecon is dened in the following parameters:
Parameter Designaon Data type
0x1604 RPDO-->axis: touch probe (TP) RECORD
0x1A04 Axis-->TPDO: touch probe (TP) RECORD
Data received from the Controller (RPDO)
Parameter Designaon Data type
0x60B8 Touch probe control word UNSIGNED_16
Data sent to the Controller (TPDO)
Parameter Designaon Data type
0x60B9 Touch probe status word UNSIGNED_16
0x60BA TP1: actual
posion - rising edge INTEGER_32
0x60BB TP1: actual posion - falling edge INTEGER_32
0x60BC TP2: actual posion - rising edge INTEGER_32
0x60BD TP2: actual posion - falling edge INTEGER_32
