P0301 – Speed to Begin DC Braking at Stop
Adjustable
Range:
0 to 18000 rpm Factory
Setting:
30 rpm
Properties:
Access groups
via HMI:
MOTOR
Description:
This parameter establishes the initial point to apply the DC braking at the stop when the inverter is disabled by
ramp, as per
Figure 11.9: (a) and (b): Actuation of DC braking at command stop (a) Run/Stop (b) General Enable
on page 11-11 .
P0302 – Voltage Applied to the DC Braking
Adjustable
Range:
0.0 to 100.0 % Factory
Setting:
20.0 %
Properties:
Access groups
via HMI:
MOTOR
Description:
This parameter sets the DC voltage (DC braking torque) applied to the motor during the braking.
The setting must be done by gradually increasing the value of P0302, which varies from 0.0 to 100.0 % of the
rated braking voltage, until the desired braking is obtained.
The 100 % braking voltage is the DC voltage value, which results in two times the rated current for the motor
with power matched to the inverter. Therefore, if the inverter has a power too much higher than the motor, the
braking torque will be too low; however, if the opposite occurs, there might be overcurrent during the braking,
as well as motor overheating.
