bit 2: Overow detection channel 1
0 on
After power-on the last position value is compared with the actual value
and possibly overows in parameter ec.33 are considered. The prerequi-
site is that the position has not changed by half the value range at power-
off. Problems with encoders whose initialisation takes longer than for the
inverter. The function must be activated here.
4 Off Overow detection not active e.g. linear - axes
