Summary of Operation Mode Fields of Line 1 and Line 2
The following tables list the possible operational mode elds of line 1 and 2 of the display in
order of precedence.
Table 9-4 Line 1 of mode eld
Order Code Meaning Description
1 FRST Fault reset Displayed after the [FAULT RESET] button is pressed.
Note: This may not be visible because of the speed of response to a fault
reset.
2 TLIM Menu setting rollback Drive is being limited by a menu setting.
3 SPHS Single phasing rollback A single phasing condition of the input line is limiting drive torque.
4 UVLT Undervoltage rollback A undervoltage condition of the input line is limiting the drive torque.
5 T OL Thermal overload rollback The drive has limited the amount of torque produced to prevent thermal
overload of the input transformer.
6 F WK Field weakening rollback This condition exists when the motor ux is low and the application re‐
quires high torque. This prevents "motor pull-out", an unstable operating
condition of the motor, by decreasing the motor torque until ux is re-
established in the motor.
7 C OL Cell overload rollback A cell current overload model has calculated a thermal overload condition
of the drive cells and the drive has limited the amount of torque allowable.
8 NET1 Network 1 limit Torque limited by network 1 setting.
9 NET2 Network 2 limit Torque limited by network 2 setting.
10 ALIM Analog torque Limit Torque limited by analog input.
11 EALM External analog Limit Drive is in torque limit due to external analog limit when in torque mode.
12 ENLM External network Limit Drive is in torque limit due to external network limit when in torque mode.
13 EMLM External menu Limit Drive is in torque limit due to external menu limit when in torque mode.
14 CIMB Cell imbalance Limit AFE cells in regen limit when the sum of the three phase voltage gains
exceed 3 pu. Each phase voltage gain is equal to the number of installed
cells per phase, divided by the active cells in that phase.
15 RLBK Roll back Appears during acceleration if drive has reached its torque limit setting.
16 RGEN Regeneration During normal deceleration, this message will be displayed when the drive
is operating in regen torque limit.
17 BRKG Dual frequency braking Appears while drive is decelerating with dual frequency braking enabled.
