Axis Parameters

ID	Parameter	Name	R/W	Update Rate Type	Description
1035	ML_AXIS_PARAM_BUS_INTERFACE_TYPE	Bus Interface Type	Read-only	Static	The parameter value is: DRIVE_BUS_INTERFACE_ECAT when the axis is associated with an EtherCAT device. DRIVE_BUS_INTERFACE_SIMULATOR when the axis is simulated.
1500	ML_AXIS_PARAM_BUS_POSITION_DEMAND	Position demand value	Read-only	EtherCAT Cyclic	Drive Position Demand Value 32-bits. There may be a 1 cycle delay.
1501	ML_AXIS_PARAM_BUS_STATUS_WORD	Drive Status Word	Read-only	EtherCAT Cyclic	Drive Axis Status Word 16-bits. DS-402 compatible drives: This is the same as the CANopen Status Word. Stepper Drives: This is the same as the STM Inputs (CoE object 0x6010). See the AKT2G-SM-Lx Object Description. Simulated Drives: N/A There may be a 1 cycle delay.
1502	ML_AXIS_PARAM_BUS_CONTROL_WORD	Drive Control Word	Read-only	EtherCAT Cyclic	Drive Axis Control Word 16-bits. DS-402 compatible drives: This is the same as the CANopen Control Word. Stepper Drives: This is the same as the STM Outputs (CoE object 0x7010). See the AKT2G-SM-Lx Object Description. Simulated Drives: N/A There may be a 1 cycle delay.
