• Specify the device No. with (D) to an even number. The specified device stores the cam position calculation result as shown
below when the calculation is completed.
• The cam position calculation does not update the cam reference position automatically.
An operation error will occur, and the cam position calculation will not be executed if:
• Cam No. specified with (S1) is outside the range of 0 to 1024. (Details code: 1)
• The cam No. data specified with (S1) does not exist in the cam open area. (Details code: 2)
• The device numbers storing the cam position calculation control data specified with (S2) are outside the range. (Details
code: 3)
• (S2) is not an even-numbered device. (Details code: 4)
• Cam position calculation type specified with cam position calculation control data is set to other than 0 or 1. (Details code:
5)
• Cam axis length per cycle is outside the range of 1 to 2147483647. (Details code: 6)
• Cam axis current value per cycle is outside the range of 0 to (cam axis length per cycle). (Details code: 7)
• The device numbers storing the cam position calculation result specified with (D) are outside the range. (Details code: 8)
• (D) is not an even-numbered device. (Details code: 9)
• The cam axis current value per cycle cannot be calculated by the cam axis current value per cycle calculation. (Details
code: 10)
