403 Decel Time 1
Default: 5.0 s
Range: 0.1 to 3200.0 s
Levels 1,2
This parameter configures the default length of time to decelerate from the value of parameter 302 (Max
Frequency) to 0 Hz. The deceleration ramp is selected by parameter 401 (Ramp Select).
Note that extremely short deceleration times may result in nuisance fault trips or may require an external
dynamic brake or regen current limit.
404 Accel Time 2
Default: 3.0 s
Range: 0.1 to 3200.0 s
Level 2
302 (Max Frequency)
401 (Ramp Select)
or Sequencer Configuration.
Note that extremely short acceleration times may result in nuisance fault trips.
405 Decel Time 2
Default: 3.0 s
Range: 0.1 to 3200.0 s
Level 2
to 0 Hz. This deceleration ramp is
401 (Ramp Select)
or Sequencer Configuration.
Note that extremely short deceleration times may result in nuisance fault trips or may require an external
dynamic brake or regen current limit.
406 DC Inject Config
Default: DC at Stop
Range: n/a
Level 2
DC injection braking may be used to stop the motor more quickly than is possible by either a ramp-to-stop
or a coast-to-stop. The Vacon 500x drive allows DC braking to be initiated either when a digital input
assigned to DC
braking becomes true, when a specified frequency is reached, or when either of these events occurs.
When using a digital input for DC braking, you must use one of the DI parameters to configure the selected
digital input for DC braking. The amount of braking force is set by parameter 408 (DC Inject Level). The
length of time that the braking force is applied is determined by the time that the selected digital input is
active.The second type of DC injection braking supported by the Vacon 500x drive is where DC braking occurs
at a
specified frequency. The duration of the braking is adjusted by parameter 407 (DC Inject Time).
With this type of braking, as the drive slows down after a Stop command, DC braking begins when the
frequency reaches the value set in parameter 409 (DC Inj Freq). If the frequency at the time of a Stop
command is less than that of DC Inj Freq, DC braking begins immediately. The braking continues for the
time period specified by parameter DC Inj Freq. Once the time period elapses, the drive may be restarted.
Parameter Value
Description
DC at Stop
DC inject only on Stop
DC at Start
DC inject only on Start
DC at Both
DC inject only on both Start and Stop
DC on Freq
DC inject only on Stop below the set frequency
407 DC Inject Time
Default: 0.2 sec
Range: 0.0 to 5.0 sec
Level 2
If parameter 406 is set to DC at Stop (see page 72), direct current is applied to the motor. This parameter,
DC Inject Time, determines how long the direct current will be applied, and how long DC is applied at Start
if programmed accordingly.
This parameter works in tandem with parameter 410 (DC Inject Config) and the other parameters
associated with DC Inject Config. That is, the time period configured by this parameter, DC Inject Time,
determines how long DC injection braking will be active. When DC injection braking is controlled by a digital
input, the braking continues for as long as the digital input is true, plus the time set by parameter 407 (DC
Inject Time). When it is controlled by frequency, however, it continues for the length of time once the drive
reaches the frequency set by parameter 409 (DC Inj Freq).
408 DC Inject Level
Default: 50.0%
Range: 0.0% to 100.0%
Level 2
Configures the amount of DC injection that will occur when direct current is injected into the motor
windings, which acts as a braking force. The amount of current is expressed as a percentage of nominal
motor current. The braking force may be applied when starting or stopping. If this parameter is set to 0.0%,
the DC injection is disabled.
409 DC Inj Freq
Default: 0 Hz
Range: 0.0 to 20.0 Hz
Level 2
