Description
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.
Indicates that the six-step regeneration torque limit is in effect. It is set
when the cell voltage gets too high, and serves to reduce the regen torque
limit to limit the energy flow from the output (motor) to the cells to pre‐
vent overvoltaging the cells.
Indicates that one or more cells are in bypass.
One of the pre-charge modes is selected and the drive is pre-charging, or
ready to pre-charge.
Appears if drive control algorithm is set to open loop test mode.
This is the typical display message during normal operation.
Appears if the current limit is due to the current profile limit curve.
Occurs when cell OT and / or transformer OT switches are active.
Occures when cell power is too high for secondary power ratings.
The input interruption time exceeded allowable limits or the function "Test
IP Interruption Time" (7126) has not been executed..
Description
No input line voltage detected.
The CR3 or "drive inhibit" input is asserted.
The drive is ready to run but is in an idle state.
The drive is magnetizing the motor or passing through the magnetizing
drive state.
