Parameters 235
115200 115.2 kbit/s. 6
58.05 Parity Selects the number of the data bits, the use and type of the
parity bit, and the number of the stop bits.
8 none 1 Eight data bits, no parity bit, one stop bit. 0
8 none 2 Eight data bits, no parity bit, two stop bits. 1
8 even 1 Eight data bits, even parity bit, one stop bit. 2
8 odd 1 Eight data bits, odd parity bit, one stop bit. 3
58.06 Control profile Selects the communication profile used by the Modbus
protocol.
ABB Classic ABB Drives profile, classic version. 0
ABB Enhanced ABB Drives profile, enhanced version. 1
DCU 16-bit DCU 16-bit profile. 2
DCU 32-bit DCU 32-bit profile. 3
58.07 Comm loss t out Defines the timeout limit for EFB communication loss
monitoring. If a communication break exceeds the timeout
limit, the function proceeds with the action defined with
parameter 58.09 Comm loss action. See also parameter
58.08 Comm loss mode.
0…60000 ms Timeout calculation factor. The actual timeout value is
calculated as follows:
Comm loss timeout × 100 ms
Example: If you set this value to 22, the actual timeout value
will be: 22 × 100 ms = 2 200 ms.
100 = 1 ms
58.08 Comm loss mode Enables/disables EFB communication loss monitoring and
defines which of the Modbus register accesses resets the
timeout counter. See parameter 58.07 Comm loss t out.
None EFB communication loss monitoring is disabled. 0
Any message EFB communication loss monitoring is enabled. Any Modbus
request resets the timeout counter.
1
Ctrl write EFB communication loss monitoring is enabled. Writing to
control or reference word resets the timeout counter.
2
58.09 Comm loss action Defines the drive operation after the EFB communication
loss monitoring awakes. See parameters 58.07 Comm loss t
out and 58.08 Comm loss mode.
None No action. 0
Fault Drive trips on fault EFB COMM LOSS (0x7540).1
Safe speed Drive generates alarm EFB COMM LOSS (0x7540) and
takes the safe speed into use (see parameter 30.02 Speed
ref safe).
2
Last speed Drive generates alarm EFB COMM LOSS (0x7540) and
takes the last speed into use (average over the previous
10 seconds).
3
58.10 Refresh settings Refreshes the settings of parameters 58.01…58.09.
Done Initial value. The value is restored after the refresh is done. 0
