Control2
USINT
Control bits
PositionSet

Sets the velocity in slave mode
Control2
Bit no. Explanation if TRUE
0

1
Reference the position (0->1)
2..7
Not used
4.1.3.3 Position referencing
An ON signal received by Ref input DI0.7 resets the counter reading to "0". This is referencing the position (if
an incremental encoder is used).
State 1 Bit 1 indicates the state of referencing.
4.1.3.4 Cam tracks
Cam tracks 0 .. 24 directly actuate digital outputs 0.0 to 2.7.
Cam tracks 25 .. 32 are software cams which the EtherCAT master, CAN master or other unit can read and
output to other modules equipped with digital outputs (extension).
4.1.3.5 Slave mode
Only one encoder is required to run several CAM modules in a synchronised manner. The module that the
encoder is connected to can use EtherCAT to transfer the position and velocity to the other modules.
