4-2-104 FE_LIMIT
/i
Type
Axis parameter (read-only)
Syntax
FE
Description
The
FE
axis parameter contains the position error in user units. This is
calculated by the demand position (
DPOS
axis parameter) minus the
measured position (
MPOS
axis parameter). The value of the Following
Error can be checked by using the axis parameters
FE_LIMIT
and
FE_RANGE
.
Arguments
N/A
Example
No example.

Type
Axis parameter (read-only)
Syntax
FE_LATCH
Description
Contains the initial
FE
value which caused the axis to put the controller
into MOTION_ERROR. This value is only set when the
FE
exceeds the
FE_LIMIT
and the
SERVO
parameter has been set to OFF.
FE_LATCH
is reset to 0 when the
SERVO
parameter of the axis is set back to ON.
Arguments
N/A
Example
No example.

Type

Syntax
FE_LIMIT
FELIMIT
Description
The
FE_LIMIT
axis parameter contains the maximum allowed Following
Error in user units. When exceeded, bit 8 of the
AXISSTATUS
parame-
ter of the axis will be set. If the
ERRORMASK
parameter has been
properly set, a motion error will be generated and WDOG enable relay
will be reset to 0.
This limit is used to guard against fault conditions, such as mechanical
lock-up, loss of encoder feedback, etc.
Arguments
N/A
Example
No example.
