C02.10 Brake Function
Default setting
0
Range
[0] Off No brake function.
[1] Resistor Brake Resistor brake is active.
[2] AC Brake AC brake is active.
C02.04 DC Brake Cut In Speed
Default setting 0.0HZ
Range
[0.0 - 400.0 Hz]
●
Function:
Set DC-brake cut-in speed to activate DC braking current,
set in par. C02.01, when ramping down.
When set to 0 the function is off.
C02.1* Brake Energy Function
Use the parameters in this group for selecting dynamic braking
parameters.
●
Function:
■ Resistor Brake:
The resistor brake limits voltage in the intermediate circuit when
the motor acts as generator. Without brake resistor, the frequency
converter eventually trips.
The resistor brake consumes surplus energy resulting from motor
braking. A frequency converter with brake stops a motor faster
than without a brake, which is used in many applications. Requires
connection of external brake resistor. An alternative to the resistor
brake is the AC brake.
■ AC Brake:
The AC brake consumes surplus energy by creating power loss in
the motor.
It is important to keep in mind that an increase in power loss causes
motor temperature to rise.
●
ATTENTION!
Resistor brake is only functional in frequency
converters with integrated dynamic brake. An external resistor must
be connected.
C02.11 Brake Resistor (ohm)
Default setting *Ω
Range
[5 - 5000 Ω]
●
Function:
Set brake resistor value.
C02.16 AC Brake, Max current
Default setting 100%
Range
[0 - 400 %]
● Function:
Enter max. permissible current for AC-braking to avoid
overheating of motor.
100% equals motor current set in par. C01.24.
