284 Actual signals and parameters
4221 ACT2
MAXIMUM
See parameter 4021 ACT2 MAXIMUM.
4228 ACTIVATE Selects the source for the external PID function activation
signal. Parameter 4230 TRIM MODE must be set to NOT
SEL.
NOT SEL
NOT SEL No external PID control activation selected 0
DI1 Digital input DI1. 1 = active, 0 = inactive. 1
DI2 See selection DI1.2
DI3 See selection DI1.3
DI4 See selection DI1.4
DI5 See selection DI1.5
DRIVE RUN Activation at drive start. Start (drive running) = active. 7
ON Activation at drive power-up. Power-up (drive powered) =
active.
8
TIMED FUNC 1 Activation by a timed function. Timed function 1 active = PID
control active. See parameter group 36 TIMED
FUNCTIONS.
9
TIMED FUNC 2 See selection TIMED FUNC 1.10
TIMED FUNC 3 See selection TIMED FUNC 1.11
TIMED FUNC 4 See selection TIMED FUNC 1.12
DI1(INV) Inverted digital input DI1. 0 = active, 1 = inactive. -1
DI2(INV) See selection DI1(INV).-2
DI3(INV) See selection DI1(INV).-3
DI4(INV) See selection DI1(INV).-4
DI5(INV) See selection DI1(INV).-5
4229 OFFSET Defines the offset for the external PID controller output.
When PID controller is activated, controller output starts
from the offset value. When PID controller is deactivated,
controller output is reset to the offset value.
Parameter 4230 TRIM MODE must be set to NOT SEL.
0.0%
0.0…100.0% Value as a percentage 1 = 0.1%
4230 TRIM MODE Activates the trim function and selects between the direct
and proportional trimming. With trimming it is possible to
combine a corrective factor to the drive reference. See
section Reference trimming on page 130.
NOT SEL
NOT SEL No trim function selected 0
PROPORTION
AL
Active. The trimming factor is proportional to the rpm/Hz
reference before trimming (REF1).
1
DIRECT Active. The trimming factor is relative to a fixed maximum
limit used in the reference control loop (maximum speed,
frequency or torque).
