NOTE: Even when the relay output is configured to indicate
alarm conditions (e .g . parameter 1401 RELAY
OUTPUT 1 = 5 (ALARM) or 16 (FLT/ALARM)), this
alarm is not indicated by a relay output .

Description and Recommended Corrective Action
Motor is hot, based on either the drive's estimate or on temperature feedback . This alarm warns that a Motor Underload
fault trip may be near . Check:
• Check for overloaded motor .
• Adjust the parameters used for the estimate (3005...3009) .
• Check the temperature sensors .
Motor load is lower than expected . This alarm warns that a Motor Underload fault trip may be near . Check:
• Motor and drive ratings match (motor is NOT undersized for the drive)
Motor is operating in the stall region . This alarm warns that a Motor Stall fault trip may be near .
This alarm warns that the drive is about to perform an automatic fault reset, which may start the motor .
• To control automatic reset, use parameter
This alarm warns that the PFA autochange function is active .
• To control PFA, use parameter
This alarm warns that the PFA interlocks are active, which means that the drive cannot start the following:
• Any motor (when Autochange is used),
• The speed regulated motor (when Autochange is not used) .
Note 1 .
This alarm warns that the PID sleep function is active, which means that the motor could accelerate when the PID sleep
function ends .
• To control PID sleep, use parameters 4022*...4026* or 4122*...4126 .*
*Not used with MicroTech II .
Performing ID run .
This alarm warns that the Override function is active, which may start the motor .
This alarm warns that the Start Enable 1 signal is missing .
• To control Start Enable 1 function, use parameter 1608 .
To correct, check:
• Digital input configuration.
• Communication settings .
This alarm warns that the Start Enable 2 signal is missing .
• To control Start Enable 2 function, use parameter 1609 .
To correct, check:
• Digital input configuration.
• Communication settings .
Emergency stop activated .
The drive is not detecting a valid encoder signal . Check for and correct:
• Encoder presence and proper connection (reverse wired, loose connection, or short circuit) .
• Voltage logic levels are outside of the specified range.
• A working and properly connected Pulse Encoder Interface Module, OTAC-01 .
Signals that a the drive is performing a First Start evaluation of motor characteristics. This is normal the first time the
motor is run after motor parameters are entered or changed . See parameter 9910 (MOTOR ID RUN) for a description of
motor models .
Not used .
This alarm warns that the condition defined by parameter 3701 USER LOAD C MODE has been valid longer that half of
the time defined by 3703 USER LOAD C TIME.
