7.6.33.3 Ramp generator stop
Maintains the state of the profile generator during operation.
l Activate with DFRFG-STOP=HIGH
l Output of the last state at DFRFG-OUT.
l Store the setpoint phase detected at DFRFG-IN.
l Approach of the setpoint phase via the profile generator after reset of the stop request.

7.6.33.4 RESET
DFRFG-RESET = HIGH:
l Resets the setpoint phase which is internally added
l Activates the profile generator
l HIGH-LOW edge at DFRFG-RESET: Detection of the setpoint phase
7.6.33.5 Detect phase difference
Monitoring of the phase difference between input DFRFG-IN and output DFRFG-OUT.
l Set limit value of the monitoring under C0754
l Activates the monitoring: DFRFG-FAIL = HIGH
l Storing the signal until DFRFG-RESET=HIGH
l The profile generator can accept a phase difference of up to ±2140000000 inc
(= 32000 revolutions).
7.6.33.6 Start via touch probe initiator (terminal X5/E5)
Function
l Set C0757 = 1.
l The function is activated by simultaneously setting the inputs
– DFRFG-QSP and DFRFG-RESET = HIGH.
l Starting procedure:
– Signals at DFRFG-QSP and DFRFG-RESET=LOW.
– Touch probe signals are otherwise ignored .
l A LOW-HIGH edge at terminal X5/E5 starts the procedure:
