PROF LIMIT ON DLY
0.00 … 100.00 h
1 = 0.01 h
0.00 h
Delay time for the Application profile protection. See also description in parameter
4421
PIPEFILL ENABLE
NOT SEL
Enables the Precharge function, which calculates reference steps.
0 = NOT SEL – Not enabled.
1 = DI1 – When DI1 is active (1), the Precharge function is active when the drive is
started. If DI1 becomes inactive (0) before the Precharge function is finished,
normal PID control is enabled.
2 = DI2 – See selection DI1.
3 = DI3 – See selection DI1.
4 = DI4 – See selection DI1.
5 = DI5 – See selection DI1.
7 = ACTIVE – The Precharge function is active at every start-up.
-1 = DI1(INV) – When DI1 is inactive (0), the Precharge function is active when the
drive is started. If DI1 becomes active (1) before the Precharge function is finished,
normal PID control is enabled.
-2 = DI2(INV) – See selection DI1(INV).
-3 = DI3(INV) – See selection DI1(INV).
-4 = DI4(INV) – See selection DI1(INV).
-5 = DI5(INV) – See selection DI1(INV).

PIPEFILL STEP
0.0 … 100.0%
1 = 0.1%
0.0%
Defines the speed step used in the Precharge function. The PID reference ramp time
is specified by parameter
The speed step is added to the reference after the time defined by parameter
has elapsed and the change in feedback defined by parameter
has not been reached.
• Speed step in percent of the maximum speed output
4423
REQ ACT CHANGE
0.0 … 100.0%
1 = 0.1%
0.0%
Defines the requested change in process feedback during the time that is set by
parameter
If the requested change in the feedback is not reached,
is added
to the speed reference.
• Value in percent of the maximum speed.
4424
ACT CHANGE
DELAY
0.1 … 6000.0 s
1 = 0.1 s
0.0 s
Defines the time that is waited after the feedback value is compared with the old
feedback value.
If parameter
is measured in the feedback value, the speed
reference stays as it is. If REQ ACT CHANGE is not seen in the feedback value, the
value of parameter
is added to the speed reference.
