C13 wire resistance setting limits
:
0.0R
~
65.530R factory default

C14 motor iron loss setting limits
:

The moment of force data in AC drive is pre-set already and don't need
to change.
C15 rotation difference increase setting limits
:
0.0%
~
9.9% factory default
:
0.0%
Motor loading rotating moment of force difference lead to different motor speed.
Rotation difference compensation is increasing AC drive output frequency by
propotion of motor loading capacity moment of force to decrease motor speed
difference.
C16 empty load current setting limits
:
0%In
~
99%In factory
default
:
30%In
Set motor current with empty load, motor rated current is 100%In
C17 correct delay setting limits
:
0.0S
~
25.5S factory
default
:
2.0S
Set correct delay data in wave filtering.
C18 rated current setting limits
:
10%In
~
200.0%In factory
default
:

Set rated current value for motor data plate, take the electronic overheat
protector AC motor protecting standard current.
C19 overload protection

:
0
~

AC drive inner overheat relay protects motor overheat.
Set correctly as follows
:
0
:

1
:
standard motor
(

)
2
:
standard motor
(
time constant 5 minutes
)
Usually don't need to adjust rotation moment of force compensation(factory
setting C12:1.0)Rotation moment of force need to be adjusted when connection
wire between AC drive and motor is too long or motor vibrating. Increase
compensation to increase motor moment of force. But there will be problems if
increase too much
■
AC drive run in unstable status because of motor over current
■
Motor overheat or vibration.
Check motor current when increasing moment of force compensation.
C11 DCInj Time@Start setting limits
:
0.0S
~
25.0S factory default
:
0.0S
DC braking time when starting
Enables motor to re-start from sliding to stop, set constant C09 DC braking
time when starting. If constant C09 is set to be “0.0S”, DC braking is invalid, AC
drive accelerate to start in min. Fre. output.
C12 rotating moment of force compensation setting limits

If stop mode(A05)selected to be slide to stop, AC drive don't execute
DC braking when AC drive stops.
Auto rotation moment of force compensation
Motor rotation moment of force may be change according to the load
capacity.Full scale rotation moment of force increase may adjust V/F
mode voltage according to needs. EC5000 AC drive adjust voltage
automatically in constant and accelerating running speed. The needing
torque is counted by the AC drive which can ensure no tripping and can
save more energy. Output voltage
