Note: Only the bits marked ‘X’ permit alteration. The permanent values ‚1’ and ‚0’ must remain unchanged since
otherwise control characters (characters < 20h) might be created which are not allowed in ASCII protocols.

Significance of parameter „m“
Key assignment
This parameter assigns a specific direction of rotation to a certain key. For mounting option “keypad below dis-
play” and the related default parameters applies the following:
0 = Up
left/right key actuation = shaft rotation ccw/cw, counting mode UP/DOWN
1 = Down
left/right key actuation = shaft rotation cw/ccw, counting mode UP/DOWN
Motor’s direction of rotation
The parameter “motor direction of rotation” enables inversion of the two output signals for motor ccw (pin B) and
motor cw (pin C) provided at the motor cable. The inversion is only effective with automated positioning. Manual
positioning operations by buttons remain unaffected.
0 = Up
Standard direction of rotation
1 = Down
Inverted direction of rotation
Shaft type
The shaft type parameter assigns the shaft type.
Some applications may call for different handling of radially and axially operated shafts what is already taken
into consideration when utilizing the Baumer IVO master. For example, only specific shafts are to be indicated in
DIM mode. When utilizing other masters (PLC or PC), this parameter may serve for general assignments.
0 = R
Radial type
1 = A
Axial type
Group
Parameter to classify groups. Individual SPAs can be assigned to one out of 8 individual groups to be started in
successive order (command „D“) to prevent collisions.
0 = Group 1
1 = Group 2
: :
7 = Group 8
Start signal for the respective group. Start command „D“ must include the related group num-
ber.
To make best use of the memory capacity, several parameters are compiled for a packed transmission. Pa-
rameter encoding is as follows:
Note: Only the bits marked ‘X’ permit alteration. The permanent values ‚1’ and ‚0’ must remain unchanged since
