Danfoss VLT 5000 Series, Инструкция по эксплуатации, Страница: 148 / 240

Motor current, parameter 520:
The value shown corresponds to the given motor cur-
rent measured as a mean value I
RMS
.
The value is filtered, which means that approx. 1.3
seconds may pass from an input value changes until
the data read-out changes values.
Torque, parameter 521:
The value shown is the torque, with sign, supplied to
the motor shaft. The value is given as a percentage of
the rated torque.
There is not exact linearity between 160% motor cur-
rent and torque in relation to the rated torque. Some
motors supply more torque than that. Consequently,
the min. value and the max. value will depend on the
max. motor current as well as the motor used.
The value is filtered, which means that approx. 1.3
seconds may pass from an input changes value until
the data read-out changes values.
NOTE
If the setting of the motor parameters does
not match the motor applied, the read-out
values will be inaccurate and may become
negative, even if the motor is not running
or is producing a positive torque.
Power, (kW), parameter 522:
The value shown is calculated on the basis of the ac-
tual motor voltage and motor current.
The value is filtered, which means that it may take ap-
prox. 1.3 seconds from an input value changes until
the data read-out changes values.
Power (HP), parameter 523:
The value shown is calculated on the basis of the ac-
tual motor voltage and motor current.
The value is indicated in the form of HP.
The value is filtered, which means that approx. 1.3
seconds may pass from an input value changes until
the data read-out changes values.
Motor voltage, parameter 524:
The value shown is a calculated value used for con-
trolling the motor.
DC link voltage, parameter 525:
The value shown is a measured value.
The value is filtered, which means that approx. 1.3
seconds may pass from an input value changes until
the data read-out changes values.
Motor temp., parameter 526:
VLT temp., parameter 527:
Only whole numbers are displayed.
Digital input, parameter 528:
The value shown indicates the signal status from the
8 digital terminals (16, 17, 18, 19, 27, 29, 32 and 33).
The read-out is binary and the digit at the extreme left
gives the status of terminal 16, while the digit at the
extreme right gives the status of terminal 33.
Terminal 53, analogue input, parameter 529:
The value shown indicates the signal value on terminal
53.
The scaling (parameters 309 and 310) does not influ-
ence the read-out. Min. and max. are determined by
the offset and gain adjustment of the AD-converter.
Terminal 54, analogue input, parameter 530:
The value shown indicates the signal value on terminal
54.
The scaling (parameters 312 and 313) does not influ-
ence the read-out. Min. and max. are determined by
the offset and gain adjustment of the AD-converter.
Terminal 60, analogue input, parameter 531:
The value shown indicates the signal value on terminal
60.
The scaling (parameters 315 and 316) does not influ-
ence the read-out. Min. and max. are determined by
the offset and gain adjustment of the AD-converter.
Pulse reference, parameter 532:
The value shown indicates any pulse reference in Hz
connected to one of the digital inputs.
External reference %, parameter 533:
The value stated gives, as a percentage, the sum of
external references (sum of analogue/bus/pulse).
Status word, parameter 534:
Indicates the status word transmitted via the serial
communication port in Hex code from the frequency
converter. See the Design Guide.
Brake power/2min., parameter 535:
Indicates the brake power transmitted to an external
brake resistor. The mean power is calculated on an
ongoing basis for the latest 120 sec.
Brake power/sec., parameter 536:
Indicates the given brake power transmitted to an ex-
ternal brake resistor. Stated as an instantaneous val-
ue.
