Parameter number identification
Parameter numbers between 0 and 999 are reserved for standard parameters.
Extensions by a supplier or user are also allowed, although using them can affect
portability between different platforms. If the parameter number is greater than
999, the parameter is supplier-specific.
Parameter number Parameter Name Data type R/W Description
1 Commanded Position REAL R Commanded position.
2 SWLimitPos REAL R/W Positive software limit switch position.
3 SWLimitNeg REAL R/W Negative software limit switch position.
4 EnableLimitPos BOOL R/W Enable positive software limit switch.
5 EnableLimitNeg BOOL R/W Enable negative software limit switch.
8 MaxVelocitySystem REAL R Maximal allowed velocity of the axis in the motion system.
9 MaxVelocityAppl REAL R/W Maximal allowed velocity of the axis in the application.
11 CommandedVelocity REAL R Commanded velocity.
12 MaxAccelerationSystem REAL R Maximal allowed acceleration of the axis in the motion system.
13 MaxAccelerationAppl REAL R/W Maximal allowed acceleration of the axis in the application.
14 MaxDecelerationSystem REAL R Maximal allowed deceleration of the axis in the system.
15 MaxDecelerationAppl REAL R/W Maximal allowed deceleration of the axis in the application.
16 MaxJerk REAL R/W Maximal allowed jerk of the axis.
1001 TargetPosition REAL R The final target position for current active moving function block
1002 TargetVelocity1 REAL R The final target velocity for current active moving function block.
1005 Duty Cycle REAL R/W The pulse duty cycle for one pulse. The valid value is 0 – 100, indicating 0% - 100%. (PWM
function can be realized by adjusting this value).
This parameter is configurable only using this Function Block. The default value is set 50.0
by the controller.
Note: For Duty Cycle, the value will be overwritten by the default setting, 50.0 when the
controller is switched from RUN mode to PRG and RUN again, or when the controller power
is cycled.
1006 PulsePerRevolution REAL R The Pulse per Revolution setting input by user in CCW GUI.
1007 TravelPerRevolution REAL R The Travel per Revolution setting input by user in CCW GUI.
