Explanation
1. For execution of this instruction, you need to use PLC FW V1.06 or later and ISPSoft V3.07 or later.
2. The INITC and ASDON (Servo-ON) instructions must be complete before this instruction is executed.
3. Slave is a servo slave station where you can specify to receive commands; the supported slave station ranges from
1 to 8. If the slave station number you are using is out of the supported range, the instruction is NOT executed. And
the Err (error) flag is ON. If the specified servo slave station cannot communicate, the Err (error) flag is also ON.
4. CAMEn is where you can activate the E-CAM control. When the BOOL value in CAMEn is ON, it indicates E-CAM
control is activated. When the BOOL value in CAMEn is OFF, it indicates E-CAM control is NOT activated. PLC sets
the servo parameter P5-88, X=0 according to the status in CAMEn.
5. CAMSt is where you can find the E-CAM status in the servo according to the servo parameter P5-88.
S: Shows the engage status (Read-only, the setting is invalid)
0: Stop
1: Engage status
2: Pre-engage status
6. Status Description:

Stop: It is the initial status of the E-CAM. The E-CAM does not operate with the master pulse. When E-CAM
function is disabled (P5-88, X=0), it returns to this status.

Pre-engage: When the engaged condition (path 1) is established, it enters this status. The E-CAM still does
not operate with the master pulse.

Engage: When it reaches pre-engaged status (path 3), it enters this status. The E-CAM starts to operate with
the master pulse.
7. Path Description:
Path 1: When the engaged condition is established (P5-88.Z), the status is Stop → Pre-engaged.

The lead pulse is determined by P5-87.

Path 2: When the E-CAM function is disabled (P5-88.X=0), it returns to Stop status.
