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 (operator keypad), 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 BAUD RATE
Defines the communication speed of
the drive in kbits per second (kb/s).
9.6 kb/s
19.2 kb/s
38.4 kb/s
57.6 kb/s
115.2 kb/s
5203 PARITY
Sets the character format to be used with the panel communication.
0 = 8 1 – 8 data bits, no parity, one stop bit.
NONE
1 = 8 2 – 8 data bits, no parity, two stop bits.
NONE
2 = 8 1 – 8 data bits, even parity, one stop bit.
EVEN
3 = 8 1 – 8 data bits, odd parity, one stop bit.
ODD
5204 OK MESSAGES
Contains a count of valid 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.
5206 FRAME ERRORS
Contains a count of the characters with a framing error that the bus
receives. For high counts, check:
• Communication speed settings of devices connected on the bus –
they must not differ.
• Ambient electro-magnetic noise levels – high noise levels generate
errors.
