Start-Up
Group 52: Panel Communication
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.

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

BAUDRATE 9.6…115.2 kbits/s
-
9.6 kbits/s
Defines the communication speed of the drive in kbits per second (kbits/s).

PARITY 0…3
1
0
Sets the character format to be used with the panel communication.
0 = 8
N
1 – No parity, one stop bit.
1 = 8
N
2 – No parity, two stop bits.
2 = 8
E
1 – Even parity, one stop bit.
3 = 8
O
1 – Odd parity, one stop bit.
5204
OK MESSAGES
0…65535
1
-
Contains a count of valid Modbus messages received by the drive.
• During normal operation, this counter is increasing constantly.
5205
PARITY ERRORS
0…65535
1
-
Contains a count of the characters with a parity error that is received from the fieldbus. For high counts, check:
• Parity settings of devices connected on the fieldbus – they must not differ.
• Ambient electro-magnetic noise levels – high noise levels generate errors.
5206
FRAME ERRORS
0…65535
1
-
Contains a count of the characters with a framing error that the fieldbus receives. For high counts, check:
• Communication speed settings of devices connected on the fieldbus – they must not differ.
• Ambient electro-magnetic noise levels – high noise levels generate errors.
5207
BUFFER OVERRUNS
0…65535
1
-
Contains a count of the characters received that cannot be placed in the buffer.
• Longest possible message length for the drive is 128 bytes.
• Received messages exceeding 128 bytes overflow the buffer. The excess characters are counted.
5208
CRC ERRORS
0…65535
1
-
Contains a count of the messages with a CRC error that the drive receives. For high counts, check:
• Ambient electro-magnetic noise levels – high noise levels generate errors.
• CRC calculations for possible errors.
