14) Parameter group 700: Error handling and protection functions
Too short ramps, short circuit on output
motor defect, system blocked, wrong
motor parameter setting
Overload
Overload
Input power over-voltage
Too high inertia
Deceleration ramp too short
Improper PID controller parameter
One input-phase missing
Motor-phase / cabling interrupted
Voltage on DC_Link too low
Environment temperature too high
Poor cabinet heat-exchange
Inverter / heatsink polluted
PWM frequency too high
Motor cable too long
The analogue signal value is below the
lower limit, programmed in F4xx
parameters
Pressure beyond limits
Inverter in SLEEP mode
MODBUS signal missing
Syncronizing time exceeded the value in
F619
No or wrong password input
Parameter change not allowed
Motor can not free rotate during dynamic
testing cycle
Hardware failure
No current signal on control board
PID controller error, due to improper PID
parameter
Timeout caused by missing watchdog
signal
Inverter error message
Inverter OK message
Resaon
Increase Accel/Decel ramp time
Check cabling / motor
Check mechanical system
Reduce BOOST
Check motor parameter setting
Reduce load
Check for right dimensioning
Check for correct supply voltage
Inverter rated voltage correct??
Use larger brake resistors
Increase deceleration time
Check power supply
Check cabling / check motor
Check power supply
Check for environment / working
conditions
Insert all parameters correctly
Check for correct inverter mounting
Inspect control cabling
Insert correct parameters for
analogue signal lower limit
Measure reference signal source
Insert correct pump controller
parameters – open water flow
Check MODBUS cabling / source –
MODBUS parameter setting
Optimize "Chatch" parameters
Insert correct password
STOP inverter to allow parameter
change (for certain parameters only)
Separate motor from drive system
Visual inspection of internal cabling
Contact EURA service-center
Visual check of internal cabling,
contact EURA service-center
Set PID parameter correctly
Check signal on dig. input - assign
digital input to watchdog function
