To put a drive into the required original position after Power-on, a reference point
approach can be carried out after switch on. Following conditions must be provided
for a reference point approach:
• limit switch
• reference point switch
• input for starting the reference point approach (if not by bus/keyboard)
Value Function of di.3...di.6, di.11, di.12
10 Start reference point approach
11 Start reference point approach inverted
12 Reference point switch
16 Right limit switch
17 Left limit switch
20 Right limit switch with reference point switch
21 Left limit switch with reference point switch
1) Starts the reference point approach with the preferred direction adjusted in
Pc.14.d
2)
Starts the reference point approach contrary to the preferred direction adjusted
in Pc.14.
3) If the right limit switch is used at the same time as reference point switch, then
the reference point approach must be started with preferred direction clockwise.
4) If the left limit switch is used at the same time as reference point switch, then
the reference point approach must be started in preferred direction counter-
clockwise.
For further information regarding the adjustment of digital inputs see Chapter 6.3.
The speed, with which the reference point search shall be carried out, can be adjusted
in the range of -3000,0...3000,0 min
can be kept for most applications.
• Positive values apply to preferred direction clockwise
• Negative values apply to preferred direction counter-clockwise
The reference point approach can be started by way of a digital input (see above);
with parameter Pd.1 (value „2") or with the first „Start positioning" command (see
Pc.10).
