12.18 DFIN (master frequency input)
Function
This function block can convert a power pulse current at the master frequency input X8
into a speed value and scale it. A master frequency can be transferred with high precision
without any offset and gain errors.
ƒ The master frequency input X8 is designed for signals with TTL level.
ƒ The zero track entry is optional.
ƒ The master frequency input X8 can be configured as a master frequency output via
C0491.
ƒ An encoder can be selected and configured via the codes:
– C0419 (encoder selection)
– C0420 (encoder increments)
– C0421 (encoder bias)
– C0427 (Type of master frequency input signal)
ƒ Output of the analog signal "DFIN_In_v"
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.
