Effective pendulum length correction - overview
The following figure provides an overview of the method used to correct the effective pendulum
length. It also demonstrates the interaction between digital and analog correction options.
Figure 9-13
Effective pendulum length correction, analog
The value in parameter P81 for the analog "effective pendulum length correction" is only
effective when the total load (LOAD) is greater than the weight of the load suspension device
(P82). In this case, the value for the load in screen 2 (PLC interface) of the diagnostic tool is
displayed in green, otherwise in black.
Analog correction
Effective pendulum length correction, digital
If digital effective pendulum length correction is to be used, the offset must be entered in
parameter P80. The command to use this is set in the DIG_HOIST_DIST_CORR control bit
(Common control word). In this case, the value for the load in screen 2 (PLC interface) of the
diagnostic tool is displayed in bold.
Digital correction
Note
The minimum effective pendulum length is limited internally to 100 mm. Lower values are not
possible.
