Description
Number of TTL pulses for emulation.
With interface module 1, defines when zero pulses are
emulated in relation to zero position received from the
encoder.
For example, with a value of 0.50000, a zero pulse is
emulated whenever the encoder position passes 0.5
revolutions. With a value of 0.00000, a zero pulse is
emulated whenever the encoder position passes zero
position.
Position of emulated zero pulses.
Selects the encoder input on interface module 2 whose
signal is echoed by or emulated to the TTL output.
See also section Encoder support (page
TTL output not in use.
Input 1 is echoed by or emulated to the TTL output.
Input 2 is echoed by or emulated to the TTL output.
Defines the number of TTL pulses per revolution for
encoder emulation output of interface module 2.
Number of TTL pulses for emulation.
With interface module 2, defines when zero pulses are

For example, with a value of 0.50000, a zero pulse is

emulated whenever the encoder position passes zero
position.
