Actual signals and parameters 259
5202 BAUD RATE Defines the transfer rate of the link. 9.6 kbit/s
9.6 kbit/s 9.6 kbit/s 1 =
0.1 kbit/s
19.2 kbit/s 19.2 kbit/s
38.4 kbit/s 38.4 kbit/s
57.6 kbit/s 57.6 kbit/s
115.2 kbit/s 115.2 kbit/s
5203 PARITY Defines the use of parity and stop bit(s). The same setting
must be used in all on-line stations.
8 NONE 1
8 NONE 1 8 data bits, no parity bit, one stop bit 0
8 NONE 2 8 data bits, no parity bit, two stop bits 1
8 EVEN 1 8 data bits, even parity indication bit, one stop bit 2
8 ODD 1 8 data bits, odd parity indication bit, one stop bit 3
5204 OK
MESSAGES
Number of valid messages received by the drive. During
normal operation, this number increases constantly.
0
0…65535 Number of messages 1 = 1
5205 PARITY
ERRORS
Number of characters with a parity error received from the
Modbus link. If the number is high, check that the parity
settings of the devices connected on the bus are the same.
Note: High electromagnetic noise levels generate errors.
0
0…65535 Number of characters 1 = 1
5206 FRAME
ERRORS
Number of characters with a framing error received by the
Modbus link. If the number is high, check that the
communication speed settings of the devices connected on
the bus are the same.
Note: High electromagnetic noise levels generate errors.
0
0…65535 Number of characters 1 = 1
5207 BUFFER
OVERRUNS
Number of characters which overflow the buffer, ie number
of characters which exceed the maximum message length,
128 bytes.
0
0…65535 Number of characters 1 = 1
5208 CRC ERRORS Number of messages with a CRC (cyclic redundancy check)
error received by the drive. If the number is high, check
CRC calculation for possible errors.
Note: High electromagnetic noise levels generate errors.
0
0…65535 Number of messages 1 = 1
53 EFB PROTOCOL Embedded fieldbus link settings. See chapter Fieldbus
control with the embedded fieldbus on page 287 .
5301 EFB
PROTOCOL ID
Contains the identification and program revision of the
protocol.
Note: You can reset this parameter only with parameter
9802 COMM PROT SEL .
0000…FFFF
hex
Format XXYY hex, where XX = protocol ID and
YY = program revision of the protocol.
5302 EFB STATION
ID
Defines the address of the device. Two units with the same
address are not allowed on-line.
1
0…65535 Address 1 = 1
All parameters
No.
