Table 54 continued: Alarms by Code Numbers
Fault Code Fault Name In Panel Description and Recommended Corrective Action
2010 MOT OVERTEMP
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.
2011 UNDERLOAD
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)
2012 MOTOR STALL
Motor is operating in the stall region. This alarm warns that a Motor Stall fault trip may be near.
2013 (note 1) AUTORESET
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 Group 31: Automatic Reset on page 33.
2014 (note 1) AUTOCHANGE
This alarm warns that the PFA autochange function is active.
• To control PFA, use parameter Group 81: PFA Control on page 41
2015 PFA INTERLOCK
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).
2016 Reserved
2017 OFF BUTTON
Note 1.
2018 (note 1) PID SLEEP
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.
2019 ID RUN Performing ID run.
2020 OVERRIDE This alarm warns that the Override function is active, which may start the motor.
2021
START ENABLE 1
MISSING
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 conguration.
• Communication settings.
2022
START ENABLE 2
MISSING
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 conguration.
• Communication settings.
2023 EMERGENCY STOP
Emergency stop activated.
2024 ENCODER ERROR
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 specied range.
• A working and properly connected Pulse Encoder Interface Module, OTAC-01.
2025 FIRST START
Signals that a the drive is performing a First Start evaluation of motor characteristics. This is normal the rst time the
motor is run after motor parameters are entered or changed. See parameter 9910 (MOTOR ID RUN) for a description of
motor models.
2026 RESERVED Not used.
2027 USER LOAD CURVE
This alarm warns that the condition de
ned by parameter 3701 USER LOAD C MODE has been valid longer that half of
the time defined by 3703 USER LOAD C TIME.
Contact your local Daikin sales representative if there is a problem.
2028 START DELAY
Shown during the Start delay. See parameter 2113 START DELAY. Contact
your local Daikin sales representative if there is a problem.
NOTE: Even when the relay output is congured 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.
