Electronic handwheel (from SW 8.1)
An electronic handwheel can be connected to the angular incremental
encoder interface. Electronic handwheels can be used to traverse the
selected axes simultaneously in manual mode. The evaluation of the
handwheel pulses is defined using the indexing dimension evaluation.
The electronic handwheel can, in the positioning mode, be activated via
an input terminal function and via PROFIBUS–DP. The signals from the
angular incremental encoder interface are velocity signals. The hand-
wheel and drive do not move in synchronism.
Acceleration and braking is realized according to P0103 and P0104.
The drive speed is limited by P0102.
The increments of the electronic handwheel can be assigned four fac-
tors using two input terminals.
These factors are specified in P0900:
Bit 1
Bit 0
Handwheel evaluation (standard)
P0900[0]

1 MSR
P0900[1]
0
1
10 MSR
P0900[2]
1
0
100 MSR
P0900[3]
1
1
1000 MSR
Sub–parameters P0900[0] up to P0900[3] can be optionally assigned
factors up between 1 and 10000.
Reader’s note
If the drive is moved using the electronic handwheel, then the drive
behavior corresponds to that of jogging, refer to Chapter 6.2.9.
Example:
The electronic handwheel supplies 100 incr./rev. One handwheel revo-
lution corresponds to a value of 1 mm.
200 handwheel revolutions in one minute correspond to a velocity of
200 mm/min. The handwheel evaluation is entered using the input sig-
nal ”angular incremental encoder handwheel evaluation, bit 0”.
The following should be parameterized:
Spindle pitch 10 mm/rev
––> P0236=10.000
Quadrature signal activated
––> P0894=0
Angular incremental encoder handwheel evaluation 10
––> P0900[1]=10
