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.
Code Description
5201 STATION ID
Defines the address of the drive.
• Two units with the same address are not allowed on-line.
• Range: 1...247
5202 BAUDRATE
Defines the communication
speed of the drive in kbits per second (kbits/s).
9.6
19.2
38.4
57.6
115.2
5203 PARITY
Sets the character format to be used with the panel
communication.
0 = 8 1 – No parity, one stop bit.
N
1 = 8 2 – No parity, two stop bits.
N
2 = 8 1 – Even parity, one stop bit.
E
3 = 8 1 – Odd parity, one stop bit.
O
5204 OK MESSAGES
Contains a count of valid Modbus messages received by the
drive.
• During normal operation, this counter is increasing constantly.
5205 PARITY ERRORS
Contains a count of the characters with a parity error that is
received from the bus. For high counts, check:
• Parity settings of devices connected on the bus – they must not
differ.
• Ambient electro-magnetic noise levels – high noise levels
generate errors.
