VLT® 5000 Crane
Description of choice:
Select No protection if no warning or tripping is
required when the motor is overloaded.
Select Thermistor warning if a warning is desired when
the connected thermistor - and thus the motor
overheats.
Select Thermistor trip if cutting out (trip) is desired when
the connected thermistor - and thus the motor
overheats.
Select ETR Warning 1,ifawarningistocome
up on the display when the motor is overloaded
according to the calculations.
Select ETR Trip 1 if tripping is desired when the motor
is overloaded according to the calculations.
The frequency converter can also be programmed
to give off a warning signal via one of the digital
outputs, in which case the signal is given both for
warning and for trip (thermal warning).
The motor data in parameters 150-158 must be set
correspondingly to the specific motor, in order for the
motor to run properly. As factory setting, the parameters
are set accordingly to the motor name plates.
If these parameters are not set correctly, it may
causeamalfunctionofthedrive.
150 STATOR RESISTANCE
Value:
Ohm
✭ Depends on unit
Function:
In this parameter the value of the motor stator
resistance for the Flux Vector control is set.
151 ROTOR RESISTANCE
Value:
Ohm
✭ Depends on unit
Function:
This parameter is for setting the value of the motor
rotor resistance for the Flux Vector control.
152 STATOR LEAKAGE REACTANCE
Value:
Ohm
✭ Depends on unit
Function:
Use this parameter for setting the value of the motor
stator leakage reactance for the Flux Vector control.
153 ROTOR LEAKAGE REACTANCE
Value:
Ohm
✭ Depends on unit
Function:
The value of the motor rotor leakage reactance for
the Flux Vector control is set in this parameter-
154 MAIN REACTANCE
Value:
Ohm
✭ Depends on unit
Function:
In this parameter the value of the motor main reactance
for the Flux Vector control is set-
✭ = factory setting. () = display text [] = value for use in communication via serial communication port
