Actual signals and parameters
182
22.08 ACC PTR Defines the source or constant for value PAR 22.08&09 of parameter 22.01.
-255.255.31 …
+255.255.31 / C.-
32768 … C.32767 Parameter index or a constant value. See parameter 10.04 EXT1 STRT PTR
for information on the difference.
100 = 1 s
22.09 DEC PTR Defines the source or constant for value PAR 22.08&09 of parameter 22.01
-255.255.31 …
+255.255.31 / C.-
32768 … C.32767 Parameter index or a constant value. See parameter 10.04 EXT1 STRT PTR
for information on the difference.
100 = 1 s
22.10 FST STP DCCL TIME Defines the time inside which the drive is stopped if the drive receives an Fast
Stop command (parameter 10.10 ).
0.00 … 1800.00 s Deceleration time 0 … 18000
23 SPEED CTRL Speed controller variables. The parameters are not visible if parameter 99.04 =
SCALAR. See section Speed controller tuning on page 71 .
Note: After the motor STANDARD ID run is successfully completed, the speed
controller parameters 23.01 GAIN and 23.02 INTEGRATION TIME are
updated to optimized crane application settings (parameter 23.01 to 15 and
parameter 23.02 to 0.5). You can manually change these settings afterwards.
23.01 GAIN Defines a relative gain for the speed controller. Great gain may cause speed
oscillation.
The figure below shows the speed controller output after an error step when
the error remains constant.
