Description Possible Reason for Trip
TR TOO SMALL
The calculated value of rotor time constant is too small. Check the
value of nameplate rpm.
MAX RPM DATA ERR
This error is reported when the MAX SPEED RPM is set to a
value outside the range for which Autotune has gathered data.
Autotune gathers data on the motor characteristics up to 30%
beyond “max speed rpm”. If MAX SPEED RPM is later increased
beyond this range, the drive had no data for this new operating
area, and so will report an error. To run the motor beyond this
point it is necessary to re-autotune with MAX SPEED RPM set to
a higher value.
STACK TRIP
The drive was unable to distinguish between an overcurrent/desat
or overvoltage trip
LEAKGE L TIMEOUT
The leakage inductance measurement requires a test current to be
inserted into the motor. It has not been possible to achieve the
required level of current. Check that the motor is wired correctly.
POWER LOSS STOP
Power Loss Stop sequence has ramped Speed Setpoint to zero or
timed out
MOTR TURNING ERR The motor must be stationary when starting the Autotune
MOTR STALLED ERR The motor must be able to rotate during Autotune
AT TORQ LIM ERR The motor is in torque limit during Autotune
FBK ENCODR CAL
The drive has failed to
set absolute position Check the encoder supports absolute position, and that the encoder
is wired correctly.
OUTPUT GBX ERROR
A non-unity output gearbox is not supported if the encoder
direction is reversed.
APP HALTED The application has been halted by the DSE Configuration Tool
APP ERROR The application has ceased execution due to an error
FIRMWARE ERROR The firmware in the drive has stopped executing
