7.6.3 Digital setpoints via frequency input
Description
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:
 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
 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
