7.8.4 Gearbox factor correction
Modified register properties lead to a changed, real register length. The difference to the par-
ameterised register length Sensor distance leads to corrections in always the same direction
(positive or negative).

0x5041:001
This correction is inefficient and leads to increased energy consumption and increased
mechanical stress. The gearbox factor correction calculates the optimum setpoint velocity of
the master value in this case.
The correction value is determined from the mean value of the position errors. The correction
value affects the setpoint velocity of the master value axis. When the gearbox factor is adjus-
ted, the constant part of the position errors is eliminated and the correction is made in the
positive and negative directions.
If the selected gain is too high, this can lead to an excessive setpoint velocity.
Parameter name Parameter index Status Function
Activation of gearbox factor correction 0x5041:016 TRUE Activates gearbox factor correction
Gearbox factor correction gain 0x5041:011 - Affects the velocity at which the gearbox
factor correction adjusts the static error
Actual gearbox factor 0x5042:005 - Outputs the value of the gearbox factor
Max. gearbox factor correction 0x5041:012 - Specifies the maximum value of the gearbox
factor correction
When the corrected gearbox factor has been detected, corrective movements occur in the
positive and negative directions. The detected gearbox factor is permanently accepted with
bit 25 = TRUE of the Activation of gearbox factor correction parameter. 0x5041:016
If the parameter Activation of gearbox factor correction = FALSE, the value of the gearbox
factor can be modified. 0x5041:016
