AX- Ser i es Mo t i o n Co n t r o l l er I n s t r u c t i o n s Ma n u a l
Name Function
axis.
*Note:
AXIS_REF_DML (FB): All function blocks contain this variable, which works as the starting program for function blocks.
Function

MC_ChangeAxisConfig_DML can be used to modify basic axis settings including the ratio between user units and pulse

number (electronic gear ratio), axis type and user units per rotary axis rotation.
The axis state must be Disabled if this function block is used.

After modification, the new axis settings cannot be retained when power off and so they will disappear after repowering

or resetting. And the axis will still run based on the settings on the axis parameter page next time.
Troubleshooting

When an error occurs in the execution of the instruction, bError will change to True. To confirm the current error state,

see the Error Code in ErrorID.
Programming Example

This example explains how MC_ChangeAxisConfig_DML is used to modify axis parameters.

Set the gear ratio denominator and gear ratio numerator (10000: 360), maximum position of the rotary axis (360) and

axis type (0). Change bRegulatorOn of MC_Power to False before MC_ChangeAxisConfig is run.
Setting Value
Data Type Timing to Take Effect
is False.
