Classic
[Address] Modbus RTU node address of the drive
19.2 kbit/s Transfer rate of the link. Same baud rate must be
(example) defined in the Modbus RTU master.
8 NONE 1 Parity and stop bits. Same parity and stop bits
(example) must be defined in the Modbus RTU master.
4 Status word as Data Word 1 from the drive
5 Actual speed as Data Word 2 from the drive
1 Control word as Data Word 1 to the drive
2 Speed reference as Data Word 2 to the drive
REFRESH Updates fieldbus settings (groups 50 to 53)
FBA Fieldbus interface as source for start and stop
P.02.12 bit15 Fieldbus interface as source to switch to EXT2
control location
FBA REF1 Fieldbus interface as source for speed reference
P.02.12 bit 8 Fieldbus interface as source for fault reset
[optional] Time between communication break detection
and the selected action. 1 = 100 ms.
CONTROL How the drive reacts to a fieldbus communication
WRITE break.
[optional] Defines the drive operation after the
communication loss monitoring awakes.
REFRESH Updates fieldbus settings (groups 50 to 53)
[Scale max] Max speed/frequency scaling value (used in
function block/visualization input
"SPEED_REF_MAX"). Must be less or equal to drive
parameter max speed/frequency.
