H.006
DC Braking Start Frequency
Parameter Range:
0.5Hz - P.004 (Maximum Speed)
Initial Setting:
1.0 Hz
Type:
Tuneable (at rest or during operation)
Refer to:
H.005 DC Braking Enable
H.007 DC Braking Current
H.008 DC Braking Time
Description:
This parameter sets the frequency at which DC Braking begins.
With DC Braking enabled (H.005=ON), braking will be activated after a stop
command when the motor speed is less than or equal to DC Braking Start
Frequency (H.006).
NOTE:
If H.005 is set to ON, and this H.006 value is set too high, faults may occur (OC,
OCb, or PUo will be displayed).
Refer also to description Section 5 of this manual, ‘Final Adjustment’, point 5.
H.007
DC Braking Current
Parameter Range:
0.0% -100.0% of motor nameplate amps)
Initial Setting:
10%
Type:
Tuneable (at rest or during operation)
Refer to:
H.005 DC Braking Enable
H.006 DC Braking Start Frequency
H.008 DC Braking Time
Description:
This parameter sets the value of DC current level applied to the motor during DC
Braking. Braking torque increases with braking voltage.
With DC Braking enabled (H.005 = ON), the braking torque provided by the motor is
defined by a percentage of motor rated amps (100.0% of motor rated amps).
Important
: If H.007 is set too high, faults may occur (OC, OCA, OCb, or PUo will be displayed)
.
H.008
DC Braking Time
Parameter Range:
0.0s - 20.0 s
Initial Setting:
3.0 s
Type:
Tuneable (at rest or during operation)
Refer to:
H.000 Motor Nameplate Volts
H.005 DC Braking Enable
H.006 DC Braking Start Frequency
H.007 DC Braking Current
Description:
This parameter sets the time period for which DC Braking will be applied.
With DC Braking enabled (H.005 = ON), braking will be activated after a stop
command when the decelerating drive reaches a speed corresponding to DC
Braking Start Frequency (H.006). The braking period ends after the programmed
time regardless of the actual motor speed. The value should be set to a level that
avoids activation at rest.
