DFH Define Home Position
Description:
Redefines the zero position of the specified axis by setting the posi-
tion value to zero at the current position.
Long description
Sets the current position of the axis to zero and saves the position
value that was valid when the command was called as offset in the
volatile memory. By adding this offset to the response, the output
values of the following commands are adapted to the new zero po-
sition:
■
■
■
Does not change the parameter values for the definition of travel
range and soft limits.
The offset is reset to zero in the following cases:
■
When switching on and rebooting the E-871.1A1N: For all axes
■
During reference point definition: For the affected axis
Format:
DFH[{␣<AxisID>}]
Arguments:
<AxisID>
Axis ID
The zero positions for all axes will be newly defined if no arguments
are specified.
Troubleshooting:
Illegal axis identifier
DFH? Get Home Position Definition
Description:
Queries the position value that is configured for the specified axis as
offset for shifting the zero position.
Long description
The offset for shifting the zero position is in the volatile memory.
The offset is reset to zero in the following cases:
■
When switching on or rebooting the Electronics: For all axes
■
During reference point definition: For the affected axis
Format:
DFH?[{␣<AxisID>}]
Arguments:
<AxisID>
Axis ID
The value for all axes will be queried if no arguments are specified.
Response:
{<AxisID>=<PositionOffset>
␊
}
<AxisID>
Axis ID
<PositionOffset>
Axis position that was valid when executing
Troubleshooting:
Illegal axis identifier
