9.2.1.10 Homing type 8
Prerequisite: an absolute encoder (SSI) is connected to to the encoder input X1 of the servo
amplifier. When the homing starts, the absolute position is read at connector X1. The reference
point is set to this position. The load does not move..
9.2.1.11 Homing type 9
Using this type of homing can damage the mechanical stop on the machine. The peak
current, Ipeak, and the continuous current, Irms, are limited for the duration of the
homing run. A more severe limiting of the current is possible. (see parameter Homing
Ipeak on screen page "Current Loop").
Mechanical stop, without limit switches, without homing switch, without feedback zero
Negative traverse, positive count direction Positive traverse, positive count direction
