MG.03.B6.02 - VLT is a registered Danfoss trademark
106 Rated motor speed
(MOTOR NOM. SPEED)
Value:
XX rpm - depends on the FC motor
[XX]
Function:
Read only parameter.
126 DC braking time (DC BRAKING TIME)
Settings:
0.0 - 60.0 sec.
[0-600]
✭
10.0 sec.
[100]
Function:
This parameter is for setting the DC braking time for
which the DC braking voltage (parameter 132) is to be
active.
0.0 sec. = OFF
Description of choice:
Set the desired time.
127 DC brake cut-in frequency
(DC BRAKE CUT-IN)
Settings:
0.0 - f
MAX
(parameter 202)
[0 - ]
✭
0.0 Hz = OFF
[0]
Function:
This parameter is for setting the DC brake cut-in
frequency at which the DC braking voltage (parameter
132) is to be active, in connection with a Stop
command.
Description of choice:
Set the desired frequency.
128 Motor thermal protection
(MOTOR THERM. PRO
TEC.)
Settings:
✭
Disable (DISABLE)
[0]
Enable (ENABLE)
[1]
Function:
The motor temperature is measured with a
thermistor (optional).
132 DC braking voltage
(DC BRAKE VOLTAGE)
Settings:
0 - 100 %
[0-100]
✭
0 %
[0]
Function:
If the stator in an asynchronous motor is supplied with
DC voltage, a braking torque will arise. The braking
torque depends on the selected DC braking voltage.
The DC braking voltage is stated as a percentage of
maximum braking voltage.
Description of choice:
Set the desired voltage as a specified percentage of
maximum braking voltage.

The DC braking voltage cannot be used as a
holding brake.
133 Start voltage (START VOLTAGE)
Settings:
0.00 - 100.00 V
[0-10000]
✭
Depends on motor
Function:
You can set the motor voltage below the field
weakening point independently of the motor current.
Use this parameter to compensate too low starting
torque.
The start voltage is the voltage at 0 Hz.
NB

NB!!!!!
If the start voltage is set too high, it can lead
to magnetic saturation and motor
overheating; the FC motor may trip. Therefore take
care when using the start voltage.
Description of choice:
Set the desired start voltage.

factory setting. ( ) = parameter window text. [ ] = value for use in communication via serial communication port
Description of choice:
If
Disable
[0] is selected no tripping is required when
the motor is overloaded.
