Example 2
Reference value (oP.64): 2000 rpm
requested setpoint: 32.37843 rpm
32.37843 rpm
———————
2000 rpm
oP.63 = x 2
30
= 17383037
Resolution and scaling factor are the same as for oP.63. Due to internal rounding, the value of ru.82 may be 1
less than the set value oP.63.
7.4.3 Rotation source oP.01
The selection of rotation direction determines the manner in which the rotation direction is adjusted. The fol-
lowing possibilities are available:
oP.01: rotation source
Value Function
0 Digital (op02), 0-limited
1 Digital (op02), absolute
2
Terminal F / R 0 limited
3 Terminal F / R -absolute
4 Terminal start / stop 0 limited
5 Terminal start / stop absolute
6 Setpoint sign + rotation direction release
7 only setpoint sign
8 Control word (Sy.50) 0-limited
9 Control word (Sy.50) absolute
10
Setpoint + control word (Sy.50) run / stop with deceleration ramp
11 Setpoint + control word (Sy.50) run / stop without deceleration ramp
0-limited or absolute
Concerning the adjustment of direction of rotation it is differentiated between two evaluations:
0 limited:
negative setpoints are set to zero, i.e. only positive setpoints are driven in accordance with the selected rotation
direction
absolute:
no sign of the set value is evaluated and it is always driven with the amount in accordance with the selected
rotation direction.
