3.2.127 FE_LATCH

3.2.128 FE_LIMIT

Description The FAST_JOG axis parameter contains the input number to be used as the
fast jog input. The number can be from 0 to 31. As default the parameter is set
to -1, no input is used for the fast jog.
The fast jog input controls the jog speed between two speeds. If the fast jog
input is set, the speed as given by the SPEED axis parameter will be used for
jogging. If the input is not set, the speed given by the JOGSPEED axis
parameter will be used.
Note: This input is active low.
Arguments N/A
Example No example.
See also AXIS, FWD_JOG, JOGSPEED, REV_JOG, SPEED.
Type Axis parameter
Syntax FASTDEC
Description The FASTDEC axis parameter contains fast deceleration ration. Its default
value is zero. If a non-zero FASTDEC is specified, the axis will ramp to zero
at this deceleration rate when an axis limit switch or position is reached.
Arguments N/A
Example No example.
See also N/A
Type Axis parameter (read-only)
Syntax FE
Description The FE axis parameter contains the position error in user units. This is calcu-
lated 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.
See also AXIS, DPOS, FE_LIMIT, FE_RANGE, MPOS, UNITS.
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.
See also N/A
Type Axis parameter
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 parameter 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.
See also AXIS, AXISSTATUS, ERRORMASK, FE, FE_RANGE, UNITS.
