500 Address
(BUS ADDRESS)
Value:
Parameter 500 Protocol = FC protocol [0]
0 - 247
✭ 1
Parameter 500 Protocol = Metasys N2 [1]
1 - 255
✭ 1
Parameter 500 Protocol = M ODBUS RTU [3]
1 - 247
✭ 1
Function:
This parameter allows the a llocation of an
address to each frequenc y converter in a serial
communication network.
Description of choice:
The individual frequency converter must be
allocated a unique a ddres s.
If the number of units connected (frequency converters
+ master) is higher than 31, a repeater must be used.
Parameter 500 Address cannot be selected
via the serial communicat i on, but must be
preset via the control unit.
501 Baudrate
(BAUDRATE)
Value:
300 Baud (300 BAU D)
[0]
600 Baud (600 BAU D)
[1]
1200 Baud (1200 BAUD)
[2]
2400 Baud (2400 BAUD)
[3]
4800 Baud (4800 BAUD)
[4]
✭9600 Baud (9600 BAUD)
[5]
Function:
This parameter is for programming the speed at which
data is transmitted via the serial port. Baud rate is
defined as the number of bits transmitted per second.
Description of choice:
The frequency converter’s transmission speed
mustbesetatavaluecorrespondingtothe
transmission speed of the master.
Parameter 501 Baudrate cannot be selected via the
serial port, but must be preset via the operating unit.
502 Coasting Stop
(COASTING SELECT)
Value:
Digital input ( DIGITAL INPUT)
[0]
Serial port (SERIAL PORT)
[1]
Logic and ( L OG IC AND)
[2]
✭Logic or (LOGIC OR)
[3]
Function:
Parameters 502-508 allow a choice between
controlling the frequency converter via the digital
inputs and/or via the serial port.
If Serial port [1] is selected, the relevant
command can only be activated if a c omma nd
is given via the serial port.
In the case of Logic and [2] the funct i on must
also be activated via a digital input.
Description of choice:
The table below shows when the motor is running
and when it is coasting, when each of the
following is selected: Digital input [0], Serial port
[1], Logic and [2] or Logic or [3].
NB!:
Note that Coast ing stop and Bit 03 in the
control word are act ive at logic ’0’.
