Manual de Funcionamiento del variador de la serie H5000
Possible reason
1: Over load
Acceleration time
3: Much quicker torsion 2: Extend acceleration
lifting
4: Disarrangement of
V/F curve
5: Low voltage of
electric net
6: controller starts
before motor stops.
7: Fluctuation or
blocking in loading
1: Over load
2: Much shorter
acceleration time
3: Much lower Motor
protection level
4: Disarrangement of
V/F curve
5: Much quicker torsion
lifting
6: Bad motor insulation
7: Disarrangement of
motor
1: Broken radiator fan
2: Blocked radiator fan
pipe
3: High temperature of
environment
5: More narrow
installation space
1: Under condition of
emergency stop
1: Bad connection
2: Disarrangement
of communication
parameter
228
Solution
1: Reduce load or replace
larger capacity of
controller
time
3: Reduce torsion lifting
rate
4: Reset V/F curve over
5: Check electric net
voltage; increase
controller capacity
6: Adopt track start mode
7: Check load condition
1: Reduce load
2: Extend acceleration
time
3: Extend protection
setting
4: Correct V/F curve
5: Reduce torsion lifting
rate
6: Check motor insulation
and replace motor
7: Use larger controller
and motor
1: Replace radiator fan
2: Clean up wind pipe
and radiator
3: Improve aeration
condition and reduce
wave frequency
4: Improve aeration
condition and air
convection
5: Improve installation
location and aeration
condition
1: After settling
emergency stop,
start up as regular
procedure
1: Check connection line
2: Reset parameter
3: Check data
transmission format
