12.19 DFOUT (master frequency output)
Function
This function block converts internal speed signals into frequency signals. Transmission is
effected with high precision (without offset and gain errors) with residual value
treatment.
ƒ
The master frequency output X8 can be configured as a master frequency input via
C0491.
ƒ
The type of the master frequency output signals can be set via C0540:
– Output of an analog signal "DFOut−ln_v"
– Output of a speed signal
– Encoder simulation of the resolver with zero track
ƒ
2 to 3 slaves connected to the master:
Use the
EMF2132IB digital frequency distributor to wire the ECS axis modules with
master digital frequency cable EYD0017AxxxxW01W01 and slave digital frequency
cable EYD0017AxxxxW01S01 .
