Description
Displayed after the [FAULT RESET] button is pressed.
Note: This may not be visible because of the speed of response to a fault
reset.
Drive is being limited by a menu setting.
A single phasing condition of the input line is limiting drive torque.
A undervoltage condition of the input line is limiting the drive torque.
The drive has limited the amount of torque produced to prevent thermal
overload of the input transformer.
This condition exists when the motor flux 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 flux is re-
established in the motor.
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.
Torque limited by network 1 setting.
Torque limited by network 2 setting.
Torque limited by analog input.
Drive is in torque limit due to external analog limit when in torque mode.
Drive is in torque limit due to external network limit when in torque mode.
Drive is in torque limit due to external menu limit when in torque mode.
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.
Appears during acceleration if drive has reached its torque limit setting.
During normal deceleration, this message will be displayed when the drive
is operating in regen torque limit.
Appears while drive is decelerating with dual frequency braking enabled.
