500 Address
Value:
Parameter 500 Protocol = FC protocol [0]
0
- 247 1
Parameter 500 Protocol = Metasys N2 [1]
1 - 255
1
Parameter 500 Protocol = MODBUS RTU [3]
1
- 247 1
Function:
This parameter allows the allocation of an address to
each frequency converter in a serial communication
network.
Description of choice:
The individual frequency converter must be allocated
a unique address.
If the number of units connected (frequency convert-
ers + master) is higher than 31, a repeater must be
used.
Parameter 500
Address cannot be selected via the se-
rial communication, but must be preset via the con-
trol unit.
501 Baudrate
Value:
300 Baud (300 BAUD) [0]
600 Baud (600 BAUD) [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 sec-
ond.
Description of choice:
The frequency converter's transmission speed must
be set at a value corresponding to the 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
Value:
Digital input (DIGITAL INPUT) [0]
Serial port (SERIAL PORT) [1]
Logic and (LOGIC AND) [2]
Logic or (LOGIC OR) [3]
Function:
Parameters 502-508 allow a choice between control-
ling the adjustable frequency drive 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 command is given via the serial
port.
In the case of
Logic and [2] the function 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].
