P1213 Restart time increment
Selects the amount the restart time is incremented for each restart of the VSD if P1210 is set
to 3, 4 or 6.
Unit: s Min: 0
P1230[2] BI: Enable DC braking
Enables DC braking via a signal applied from an external source. Function remains active
while external input signal is active.
DC braking causes the motor to stop rapidly by applying a DC braking current (current
applied also holds shaft stationary).
When the DC braking signal is applied, the VSD output pulses are blocked and the DC
current is not applied until the motor has been sufficiently demagnetized.
Unit: - Min: 0:0
Settings: 722.0=Digital input 1 (requires P0701 set to 99, BICO)
722.1=Digital input 2 (requires P0702 set to 99, BICO)
722.2=Digital input 3 (requires P0703 set to 99, BICO)
722.3=Digital input 4 (requires P0704 set to 99, BICO)
722.4=Digital input 5 (requires P0705 set to 99, BICO)
722.5=Digital input 6 (requires P0706 set to 99, BICO)
722.6=Digital input 7 (via analog input 1, requires P0707 set to 99)
722.7=Digital input 8 (via analog input 2, requires P0708 set to 99)
Index: P1230[0]: VSD in "Auto" mode
Caution: Frequent use of long periods of DC braking can cause the motor to overheat.
Note: This delay time is set in P0347 (demagnetization time). If this delay is too short, overcurrent trips can occur.
P1232 DC braking current
Defines the level of DC current in [%] relative to the rated motor current (P0305).
Unit: % Min: 0
P1233 Duration of DC braking
Defines duration for which DC injection braking is to be active following an OFF1 command.
Unit: s Min: 0
Value: P1233=0: Not active following OFF1
Caution Frequent use of long periods of DC braking can cause the motor to overheat.
Note: The DC braking function causes the motor to stop rapidly by applying a DC braking current (the current applied also
holds the shaft stationary). When the DC braking signal is applied, the VSD output pulses are blocked and the DC
current not applied until the motor has been sufficiently demagnetized (demagnetization time is calculated automatically
from motor data).
P1236 Compound braking current
Defines DC level superimposed on AC waveform. The value is entered in [%] relative to rated
motor current (P0305).
Unit: % Min: 0
Value: P1236=0: Compound braking disabled
P1236=1 - 250: Level of DC braking current defined as a [%] of rated motor current (P0305)
Dependency: Active after OFF1 / OFF3 command
Note: Increasing the value will generally improve braking performance; however, if you set the value too high, an overcurrent
trip may result.
P1240 Configuration of Vdc controller
Enables / disables Vdc controller.
Unit: - Min: 0
Details: The Vdc controller dynamically controls the DC link voltage to prevent overvoltage trips on high inertia systems.
Settings: 0=Vdc controller disabled
1=Vdc-max controller enabled
Note: Vdc max automatically increases ramp-down times to keep the DC link voltage (r0026) within limits (P2172).
P1260 Source of changeover control
Selects the possible sources for contactor changeover control.
Unit: - Min: 0
Settings: 0 Bypass disabled
1 Controlled by VSD trip
2 Controlled by DIN – see P1266
3 Controlled by DIN and VSD trip

Note: When using setting 4...7, the setpoint is to be preset via the USS protocol (BOP or COM link) or the motor
potentiometer. Analog presettings of setpoints are not possible.
r1261 BO: Contactor control word
Output word from the bypass feature that allows external connections to be made.
Unit: - Min: -

P1262 Bypass dead time
