If normal or timed injection braking is selected, the drive will use ramp mode to stop on loss of the supply. If ramp stop followed by injection braking is
selected the drive will ramp to a stop and then attempt to apply DC injection. At this point, unless the mains has been restored the drive is likely to
initiate a UU trip.
2rd.th
The drive detects mains loss when the DC bus voltage falls below Vml
1
. The drive then enters a mode where a closed-loop controller attempts to hold
the DC bus level at Vml
2
. This causes the motor to decelerate at a rate that increases as the speed falls. If the mains is re-applied it will force the DC
bus voltage above the detection threshold Vml
1
and the drive will continue to operate normally. The output of the mains loss controller is a current
demand that is fed into the current control system and therefore the gain parameters Pr 4.13 and Pr 4.14 must be set up for optimum control. See
Pr 4.13 and Pr 4.14 on page 50 for set-up details.
The following table shows the voltage levels used by drives with each voltage rating.
When the drive is carrying out a mains loss stop or ride through, the drive’s left hand display will show ‘AC’.
This parameter changes the functions of terminals B4, B5 and B6, which are normally associated with the enabling, starting and stopping the drive.
This also writes to parameter Pr 6.40 to enable and disable the input latches.
Pr 6.40, Pr 8.22, Pr 8.23 and Pr 8.24 are also saved when this parameter is modified.
A change to this parameter is only actioned when the drive is stopped, tripped or disabled. If the drive is active when this parameter is changed, the
parameter will return to its pre-altered value on exit of edit mode.
In mode 6 the user is free to assign the terminals as appropriate to their application.
Defines the current level used during DC injection braking as a percentage of rated active current as defined by Pr 5.07.
Defines the time of injection braking where this is specified in stopping modes 3 and 4 (see Pr 6.01 on page 69).
