Select ETR warning if you want a warning when the
motor is overloaded according to the calculations.
You can also programme the frequency converter to
give a warning signal via the digital output.
Select ETR Trip ifyouwantatripwhenthemotor
is overloaded according to the calculations.
Select ETR w arning 1-4 if you want a warning when
the motor is overloaded according to the calculations.
You can also programme the frequency converter to
give a warning signal via one of the digital outputs.
Select ETR Trip 1-4 if you want a trip when the motor
is overloaded according to the calculations.
NB!:
This function cannot protect the individual
motors in the case of motors linked in parallel.
130 Start frequency
(START FREQUENCY)
Value:
0.0 - 10.0 Hz
✭ 0.0 Hz
Function:
Thestartfrequencyisactiveforthetimesetin
parameter 120 Start delay, after a start command.
The output frequency will ’jump’ tothenextpreset
frequency. Certain motors, such as conical anchor
motors, need an extra voltage/start frequency
(boost) at start to disengage the mechanical brake.
To achieve this parameters 130 Start freque ncy
and 131 Initial voltage are used.
Description of choice:
Set the required start frequency. It is a precondition
that parameter 121 Start function,issetto
Start frequency/voltage clockwise [3] or Start
freque ncy voltage in reference direction [4] and
that in parameter 120 Start delay atimeisset
and a reference signal is present.
NB!:
If parameter 123 is set higher than parameter
130, the start delay function (parameter
120 and 121) will be skipped.
131 Initial voltage
(INITIAL VOLTAGE)
Value:
0.0 - 200.0 V
✭ 0.0 V
Function:
Initial voltage is active for the time set in parameter
120 Start delay , after a start command
.This
parameter can be used for example for lifting/dropping
applications (conical anchor motors).
Description of choice:
Set the required voltage necessary to cut out the
mechanical brake. It is assumed that parameter
121 Start function,issettoStart frequency/voltage
clockwise [3] or Start frequency/voltage in reference
direction [4] and that in parameter 120 Start delay a
time is set, and that a reference signal is present.
132 DC brake voltage
(DC BRAKE VOLTAGE)
Value:
0 - 100% of max. DC brake voltage
✭ 0%
Function:
In this parameter, the DC brake voltage is set which is
to be activated at stop when the DC brake frequency
set in parameter 127 DC brake cut-in frequency is
reached, or if DC braking inverse isactiveviaadigital
input or via serial communication. Subsequently,
the DC brake voltage will be active for the time
set in parameter 126 DC brake time.
Description of choice:
To be set as a percentage value of the max. DC
brake voltage, which depends on the motor.
133 Start voltage
(START VOLTAGE)
Value:
0.00 - 100.00 V
✭ Depends on unit
Function:
A higher start torque can be obtained by increasing
the start voltage. Small motors (< 1.0 kW)
normally require a high start voltage.
✭ = factory setting. () = display text [] = value for use in communication via serial communication port
