Capture/Trip
The Capture Input/Trip Output point is a high speed I/O point which can be used for time critical events in motion
applications.
Capture Input
When configured as a capture input I/O point 13 has programmable filtering with a range of 50nS to 12.9
µS and has a resolution of 32 bits. The capture input needs to be pulled up to TTL using a 10k ohm resistor.
To configure the Capture input
S13=60,<0/1> 'configure IO13 as a capture input, <active HIGH/LOW>
FC <0-9>
'set input filtering to <range>
Trip Output
When configured as a trip output I/O 13 trip speed is 150 nS with 32 bit resolution.
To configure the Trip output
S13=61,<0/1> 'configure IO13 as a trip output, <active HIGH/LOW>
CW=10
'set the trip output pulse width to 500 nS
