Control signals for ramp-function generator

The ramp-function generator operating mode can be preset by the following control signals:
Ramp-function generator start (control word 1.bit 5):
1 = Setpoint is injected at ramp-function generator input
0 = Ramp-function generator is stopped at current value (generator output is injected as generator
input).
Enable setpoint (control word 1.bit 6):
1 = Setpoint enabled at ramp-function generator input
0 = Ramp-function generator setting 1 is activated and 0 applied at the input (generator output is
reduced to 0)
Set ramp-function generator:
1 = The ramp-function generator output is set to the setting value (selected in P639)
Enable ramp-function generator (control word 1.bit 4):
0 = Ramp generator disabled, generator output is set to 0
1 = Ramp-function generator enabled
Ramp-up integrator operation (parameter P302):
See below and Section 11, Parameter List, parameter P302
Enable switchover of ramp-up integrator (select via P646):
See below
Ramp-function generator settings 2 and 3
See below
Ramp-function generator tracking ON (parameter P317):
See below and Section 11, Parameter List, parameter P317
Set ramp-function generator on shutdown (parameter P318):
See Section 11, Parameter List, parameter P318
Bypass ramp-function generator:
1 = Ramp-function generator operates with ramp-up/ramp-down time of 0
The function is controlled via the binector selected in P641.
The ramp generator can also be bypassed in INCHING, CRAWLING and INJECTION OF FIXED
SETPOINT modes.
