Actual signals and parameters 255
Group 52: Panel comm
This group defines the communication settings for the control panel port on the drive.
Normally, when using the supplied control panel, there is no need to change settings
in this group.
In this group, parameter modifications take effect on the next power-up.

5201
STATION ID
1…247 1 1
Defines the address of the drive. Two units with the same address are not allowed on-
line.
• Range: 1…247

BAUD RATE
9.6 … 115.2 kbits/s - 9.6 kbits/s
Defines the transfer rate of the link.

5203
PARITY
0…3 1 0
Defines the use of parity and stop bit(s). The same setting must be used in all on-line
stations.
0 = 8N1 – 8 data bits, no parity, one stop bit.
1 = 8N2 – 8 data bits, no parity, two stop bits.
2 = 8E1 – 8 data bits, even parity indication bit, one stop bit.
3 = 8O1 – 8 data bits, odd parity indication bit, one stop bit.
5204
OK MESSAGES
0…65535 1 -
Number of valid messages received by the drive. During normal operation, this number
increases constantly.
5205
PARITY ERRORS
0…65535 1 -
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.
5206
FRAME ERRORS
0…65535 1 -
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.
5207
BUFFER
OVERRUNS
0…65535 1 -
Number of characters which overflow the buffer, in other words, number of characters
which exceed the maximum message length, 128 bytes.
