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. Refer to torque
limits settings in Table 3-8.
A Single phasing condition of the input line is limiting
drive torque.
A Under Voltage 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 requires high torque. This prevents "motor
pull-out," an unstable operating condition of 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 produced.
During normal deceleration, this message will be dis-
played because the drive is preventing the motor from
regenerating power back into the drive.
Appears while drive is decelerating with dual frequency
braking enabled.
Appears during acceleration if drive has reached its
torque limit setting.
Indicates that one or more cells is in bypass.
Appears if drive control algorithm is set to Open Loop
Test Mode.
Torque limited by network 1 setting.
Torque limited by network 2 setting.
Torque limited by analog input.
This is the typical display message during normal
operation.
