ABB DRIVES Communication profile "ABB Drives"
[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.
NONE1STO Parity and stop bits. Same parity and stop bits must be
PBIT defined in the Modbus RTU master.
(example)
COMM.CW Fieldbus interface as source for start and stop
COMM.CW Fieldbus interface as source to switch to EXT2 control
location
COMM.REF Fieldbus interface as source for speed reference
COMM.CW Fieldbus interface as source for fault reset
102 Actual speed value taken from 01.02
e.g. 105 Actual value2. E.g torque taken from 01.05
[optional] How the drive reacts to a fieldbus communication
break.
[optional] Time between communication break detection and the
selected action.
[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.
