.xx %
Refer to Chapter 6: "The Keypad" - The Keypad Menus (DIAGNOSTICS).
FLD. FIRING ANGLE 184
.xx DEG
Refer to Chapter 6: "The Keypad" - The Keypad Menus (DIAGNOSTICS).
FIELD I FBK. 300 .xx %
Field current feedback, as a percentage of the calibrated level.
FIELD I FBK.AMPS 539
.x A
FIELD I FBK calibrated in Amps.
UP TO FIELD 618 FALSE / TRUE
Field current feedback is above FIELD I THRESHOLD when TRUE. This may be used as part of a mechanical brake release strategy.
WEAK PID ERROR 1185
.xx %
Input error, as a percentage of calibrated Volts, to the field weakening controller. This is formed from the spill-over of filtered BEMF above the
MAX VOLTS setting.
WEAK PID OUT 1186
.xx %
Output field reduction demand, as a percentage of calibrated field current, from the field weakening controller.
FIELD STATE 1187 See below
State of the field controller.
0 : FIELD INIT
1 : FIELD QUENCH
2 : FIELD STANDBY
3 : FIELD FULL FLD
4 : FIELD TIMER
indicates that the FLD.QUENCH DELAY timer is counting down
5 : FIELD ERROR
6 : LOCAL BEMF
BEMF SOURCE 1273 LOCAL BEMF / BEMF INPUT
Selects the source of the back-emf feedback into the field weakening control loop.
Setting LOCAL BEMF makes use of the back-emf measured at the armature terminals.
Setting BEMF INPUT uses the value in the parameter BEMF INPUT as the feedback for the field weakening control.
