9.5.3 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.

The ramp-function generator settings preset via the binectors selected in P637 and P638 have priority
over the generator setting specified via the ramp-up integrator.
The selection parameter for the switchover to RFG setting 2 is set to 129 in the factory setting (binector
B0129: 0=positive speed setpoint / hoist, 1=negative speed setpoint / lower). Thus, switching takes
place automatically to RFG setting 1 for hoisting and to RFG setting 2 for lowering.
