ƒ QSP is activated using DFRFG1−QSP = HIGH.
ƒ With DFRFG1−QSP = LOW, QSP is deactivated. The setpoint is
approached via the profile generator.
The function ramp−function generator stop" keeps the state of the profile
generator during operation. Setpoints and actual values are continued to be

ƒ The function "ramp−function generator stop" is activated with
DFRFG1−STOP = HIGH.
– The last status is output at DFRFG1−OUT.
ƒ With DFRFG1−STOP = LOW the function ramp−function generator
stop" is reset. The setpoint is approached via the profile generator.
ƒ With DFRFG1−RESET = HIGH, the profile generator is activated.
Internally added−up set phases and actual phases are reset.
ƒ The set phase is detected using a HIGH−LOW signal at DFRFG1−RESET.
