The cams are independent to each other so the cam state register can take on 256
combinations to control a machine.
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

0(LSB)

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).

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. WDGA 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!
