It is possible to select position actual value inversion using parameter
P0231.
Spindle drive with For spindle drives with gearboxes, an external zero mark
gearbox (BERO) (BERO) should be provided as reference point if the spindle has to be
positioned.
For multi–stage gearboxes, the gearbox stage ratios must be taken into
account. The ratios must be entered via parameter P0237 (gearbox
revolutions) and P0238 (load revolutions). For parameter set 0, the ra-
tio of the first gearbox stage can be defined using SimoCom U in the
menu screen "Mechanical system" (1:1 is the basic setting).
Additional gearbox stage ratios must be entered using the Expert list
(P0237:x, P0238:x; x = 1 to 7).
Example:
If a changeover gearbox with a ratio of 1:1 or 1:4 is used, for the 1st
gearbox stage, parameters P0237:0 and P0238:0 remain unchanged
(because 1:1) and for the ratio 1:4, the following values are entered into
parameters P0237:1 = 1 and P0238:1 = 4. These values become valid
after "Power on".
The ratio can be checked using parameter P0132. In this case, the
distance between two zero marks is displayed in degrees. If the values
which are displayed deviate from 360 degrees, then the gear–up/gear–
down ratio was not correctly parameterized.
