10.8.3 Digital setpoints via frequency input
It is possible to configure the digital inputs E1 and E2 of the standard I/O or
application I/O as frequency input. This enables you to select a digital frequency
as setpoint or actual value:
l For operation with standard I/O
– single-tracked: 0 ... 10 kHz at X3/E1
– two-tracked: 0 ... 1 kHz at X3/E1 and X3/E2
l For operation with application I/O
– single-tracked: 0 ... 100 kHz at X3/E1
– two-tracked: 0 ...100 kHz at X3/E1 and X3/E2
