Description
Motor is hot, based on either the drive's estimate or
on temperature feedback. This alarm warns that a
Motor Overload fault trip may be near. Check:
• Check for overloaded motor.
• Adjust the parameters used for the estimate
(3005...3009).
• Check the temperature sensors and Group 35
parameters.
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)
• Settings on parameters 3013 to 3015
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 group
31 AUTOMATIC RESET.
This alarm warns that the PFA autochange function
is active.
• To control PFA, use parameter group 81 PFA
and see also application macro Pump
alternation.
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.
