LIMITING PREF: 121.12 Default: FALSE Range: FALSE / TRUE
This diagnostic is TRUE if the PID output has reached the Limit value.
PID OUTPUT
PREF: 121.09 Default: —.xxxx Hz Range: —.xxxx Hz
This diagnostic shows the output of the position loop PI loop only.
SPD FEEDFORWARD
PREF: 121.08 Default: —.xxxx Hz Range: —.xxxx Hz
This diagnostic shows the Speed Feedforward from other blocks, e.g. inertia compensation.
POSITN INTEGRAL PREF: 121.06 Default: —.xxxx deg Range: —.xxxx deg
This diagnostic shows the value of the position loop integral.
POSITION ERROR PREF: 121.05 Default: —.xxxx deg Range: —.xxxx deg
This diagnostic shows the instantaneous position error.
POSN LOOP RSPONS PREF: 121.04 Default: —.x ms Range: —.x ms
This diagnostic shows the nominal response time of the position loop.
MODE PREF: 121.16 Default: 0 Range: See below
This diagnostic shows the operating mode of the position loop. (Range: Enumerated – 0: DISABLED, 1: ENABLED, , 2: UNSYNCHRONISED, 3:
SYNCHRONISED , 4: ABSOLUTE,.)
Enumerated Value : Mode
0 : DISABLED The position loop is disabled.
1 : ENABLED The position loop is enabled, but not operating
2 : UNSYNCHRONISED The position loop is operating, but this drive has not been
synchronised to the master by a Move To Master operation
3 : SYNCHRONISED The position loop is operating, and the drive has been
synchronised to the master, by a Move To Master operation
4 : ABSOLUTE The position loop is operating with demands from the Phase
