2.8 DFIN_IO_DigitalFrequency
2.8.1 Inputs_DFIN
Digital frequency input (module number 21)
This SB can convert and normalise a pulse current at the digital frequency input X9 into a speed value.
• The transmission is very precise without offset and gain errors.
• In addition, this SB provides the angle correction value DFIN_dnIncLastScan_p which is
required for angle processing in touch probe processes.

VariableName
DataType SignalType Address DIS DIS format Note
DFIN_nIn_v Integer Velocity %IW21.0 C0426 dec [rpm] Value in incr./msec
DFIN_bEncFaultCable_b Bool binary %IX21.1.0 - - TRUE = monitoring “FaultEncCa-
ble” has been triggered, because
X9/8 has no voltage applied, and
so the digital frequency coupling
is interrupted
DFIN_bTPReceived_b Bool binary %IX21.1.2 - - Receive touch probe (TP)
DFIN_dnIncLastScan_p Double-integer position %ID21.1 - - ∆inc between TP and start of
task
Stop!
The digital frequency input X9 cannot be used if
• you use digital frequency output X10 (C0540 = 0, 1, 2) and
• an incremental encoder/SIN-COS encoder!
Tip!
The process image is newly created for every task the SB is used in.
• If DFIN_nIn_v , DFIN_dnIncLastScan_p and DFIN_bTPReceived_b are used in several tasks,
every task gets its own SB process image.
• This process is different from the previous process image principle!
• The digital frequency input X9 is dimensioned for signals with TTL levels.
• The input of a zero track is optional.
