Actual signals and parameters
225
52 PANEL COMM Communication settings for the control panel port on the drive
5201 STATION ID Defines the address of the drive. Two units with the same address are not
allowed on-line. 1
1…247 Address 1 = 1
5202 BAUD RATE Defines the transfer rate of the link. 9.6
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 No parity bit, one stop bit 0
8 NONE 2 No parity bit, two stop bits 1
8 EVEN 1 Even parity indication bit, one stop bit 2
8 ODD 1 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, i.e. 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 an 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
embedded fieldbus .
5302 EFB STATION ID Defines the address of the device. Two units with the same address are not
allowed on-line. 1
0...247 Address 1 = 1
