BASIC commands
3.2.129 FE_LIMIT_MODE
/i
Type Axis parameter
Syntax FE_LIMIT_MODE=value
Description When this parameter is set to 0, the axis will cause a MOTION_ERROR
immediately when the FE exceeds the FE_LIMIT value.
If FE_LIMIT_MODE is set to 1, the axis will only generate a
MOTION_ERROR when the FE exceeds FE_LIMIT during 2 consecutive
servo periods. This means that if FE_LIMIT is exceeded for one servo period
only, it will be ignored.
The default value for FE_LIMIT_MODE is 0.
Arguments N/A
Example No example.

3.2.130 FE_RANGE
/i
Type Axis parameter
Syntax FE_RANGE
Description The FE_RANGE axis parameter contains the limit for the Following Error
warning range in user units. When the Following Error exceeds this value on
a servo axis, bit 1 in the AXISSTATUS axis parameter will be turned on.
This range is used as a first indication for fault conditions in the application
(compare FE_LIMIT).
Arguments N/A
Example No example.

3.2.131 FHOLD_IN
/i
Type Axis parameter
Syntax FHOLD_IN
FH_IN
Description The FHOLD_IN axis parameter contains the input number to be used as the
feedhold input. The valid input range is 0 to 31. Values 0 to 15 represent phys-
ically present inputs of TJ2-MC64 I/O connector and are common for all axes.
Values 16 to 31 are mapped directly to Drive inputs that are present on the
CN1 connector. They are unique for each axis. It depends on the type of
Servo Drive which Servo Drive inputs are mapped into inputs 16 to 31.
As default the parameter is set to -1, no input is used for feedhold.
Note: This input is active low.
If an input number is set and the feedhold input turns set, the speed of the
move on the axis is changed to the value set in the FHSPEED axis parameter.
The current move is not cancelled. Furthermore, bit 7 of the AXISSTATUS
parameter is set. When the input turns reset again, any move in progress
when the input was set will return to the programmed speed.
Note: This feature only works on speed controlled moves. Moves which are
not speed controlled (CAMBOX, CONNECT and MOVELINK) are not
affected.
Arguments N/A
Example No example.
