Description
Communication settings for the control panel port on the drive
Defines the address of the drive. Two units with the same address are not
allowed on-line.
Address
Defines the transfer rate of the link.
9.6 kbit/s
19.2 kbit/s
38.4 kbit/s
57.6 kbit/s
115.2 kbit/s
Defines the use of parity and stop bit(s). The same setting must be used in all
on-line stations.
No parity bit, one stop bit
No parity bit, two stop bits
Even parity indication bit, one stop bit
Odd parity indication bit, one stop bit
Number of valid messages received by the drive. During normal operation,
this number increases constantly.
Number of messages
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.
Number of characters
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.
Number of characters
which exceed the maximum message length, 128 bytes.
Number of characters
Number of messages with an CRC (cyclic redundancy check) error received
by the drive. If the number is high, check CRC calculation for possible errors.
Note: High electromagnetic noise levels generate errors.
Number of messages
Embedded fieldbus link settings. See chapter
embedded fieldbus.
Defines the address of the device. Two units with the same address are not
allowed on-line.
