DL100 Series Universal Low-Power Inverter
Detailed Description of Functions 35
and the motor runs freely and stops. During a free stop, restart the motor after the
motor has completely stopped running, otherwise an over-current or over-voltage
fault may occur.
This parameter group is used to set the DC braking parameters when stopping.
The initial frequency of DC braking at stop ([F1.05]) is set. When the output
frequency of the inverter is lower than this setting parameter when the inverter is
stopped, the inverter will block the output, start the DC braking function, and stop
the DC braking.
The action time is set by parameter [F1.07]. When the stop DC braking action
time is set to 0, the stop DC braking function is invalid.
The stop DC braking current refers to the percentage of the inverter's rated
current.
This parameter is valid for the inverter with built-in braking unit and is used to
define the action parameters of the built-in braking unit of the inverter. When the
internal DC side voltage of the inverter is higher than the initial voltage of
dynamic braking, the built-in braking unit will act. If there is an external braking
resistor, the internal DC side pumping voltage energy of the inverter will be
released through the braking resistor to make the DC voltage drop. When the DC
side voltage drops below a certain value ([F1.08]), the built-in braking unit of the
inverter is turned off, as shown in Figure 6-5.
