Function:
These parameters can be read out via the serial
communication port and via the display in Display
mode, see also parameters 009 - 012.
Description of choice:
Reference %, parameter 515:
The value shown corresponds to rhe total
reference (sum of digital/analogue/preset/bus/freeze
ref./catch-up and slow-down).
Reference Unit, parameter 516:
Gives the present value of terminals 17/29/53/54/60 in
the unit resulting from the choice of configuration in
parameter 100 (Hz, Nm or rpm) or in parameter 416.
See also parameters 205 and 416, if required.
Feedback, parameter 517:
Indicates the status value of terminals 33/53/60 at the
unit/scale selected in parameters 414, 416 and 416.
Frequency, parameter 518:
The value shown corresponds to the actual motor
frequency f
M
(without resonance dampening).
Frequency x scale, parameter 519:
The value shown corresponds to the actual motor
frequency f
M
(without resonance dampening) multiplied
by a factor (scaling) set in parameter 008.
Motor current, parameter 520:
The value shown corresponds to the given motor
current 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
current 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.
NB!:
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
actual motor voltage and motor current.
The value is filtered, which means that it may take
approx. 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
actual 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 controlling 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
influence 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
influence 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.
