n Independent execution does not take place even when turning on the input signal.

Check whether the input signal on time is maintained for about 1 second. The power saving state will be deactivated if an input signal is turned on when the robot is in the power saving state. Considering that independent execution will take place after the power saving state is deactivated completely, the input signal on time should include the time for the robot to shift to the power saving on state to the power saving off state.

 

n Trying but hard to execute a Move command independently.

For executing a Move command independently, the relevant additional axis control state should be invalid. The ‘AXISCTRL OFF” command or the ‘362: Axis control status manual setting’ should be executed to turn the additional axis control state into invalid state.

 

The invalid state of an additional axis control will be displayed through the state flag of the initial screen.

 

 

n The“E1480 There is an axis being used by another task” situation occurred. How can I analyze possible causes?

While it is a command related to the spot welding, it is required for the relevant additional axis to move when the Move command is executed independently. In case of E1480, when the input signal is turned on and the command, which needs to be executed independently, is analyzed, if it is found that the command requires the movement of the additional axis, it is needed to check whether the relevant additional axis moves due to the independent execution of the previous command. In relation to that, if the movement is still in progress, the message will be displayed.

 

When the state of input signals is checked from the history of E1480, there may be more than 2 input signals turned on for independent execution. The following figure is about a case in which, as DI104 is fed, a command that requires P1 to move to the 180-degree position is received while P1 is moving to the 0 degree position.

 

 

In order to take measures against errors, if an additional axis is being executed independently, it is required to supplement the PLC circuit to prevent an axis identical to the axis from being executed independently.
