7.5.2 CAM-enable-register
Each cam can separately be enabled or disabled by the object 6301h sub-Index 01h. The cams are represented
by the bits of the object, 1 = ON, 0 = OFF. For example CAM 2, CAM 4 and CAM 7 shall be enabled, so the
configuration is:
Position 7(MSB) 6 5 4 3 2 1 0(LSB)
Type CAM 8 CAM 7 CAM 6 CAM 5 CAM 4 CAM 3 CAM 2 CAM 1
Value 0 1 0 0 1 0 1 0
Table 7.15: CAM-enable-register
– Value 4Ah
That means writing 4h to object 6301h sub-index 01h. The cams 2, 4 and 7 are now enabled and can switch
depending on their configured limits and the position value.
7.5.3 CAM-polarity -register
The cam-polarity-register object 6302h sub-index 01h alters the polarity of the corresponding cam states in cam
state register. By default all cams are high (=1b) when the position value is within the limits of the cam.
E.g. if the cam polarity register is set to 13h (=00010011b) the cams 1, 2 and 6 are inverted (Bit = 0b (Low), while
position value inside limits).
Position 7(MSB) 6 5 4 3 2 1 0(LSB)
Type CAM 8 CAM 7 CAM 6 CAM 5 CAM 4 CAM 3 CAM 2 CAM 1
Value 0 0 0 1 0 0 1 1
Logic Default Default Default Inverted Default Default Inverted Inverted

7.5.4 CAM-Low-Limit
The object CAM-Low-Limit sets the lower switching position for a cam. Each cam has its own CAM-low-limit
object. (See object dictionary 6310h...6317h). Within the low-limit objects the sub index represents a cam
channel. The encoder provides one channel with 8 cams.
•
The cam-high-limit always has to be lower than the corresponding low-limit.
Therefore the high-limit must be usually configured before the corresponding low-
limit!
7.5.5 CAM-High-Limit
The CAM-High-Limit defines the upper switching position for a cam, similar to the CAM-low-limit. Therefor each
cam has its own high-limit-object (see object dictionary
6320h .. 6327h).
7.5.6 CAM-Hysteresis
The CAM-Hysteresis defines the width of the cam hysteresis for each single cam (see object dictionary
6320h...6327h).
