P-36 Communication Configuration
The Optidrive communication parameters are set using P-36, which has three indices as follows:-
P-36
Serial Communications Configuration
Index 1 : Address
Range : 0 – 63, default : 1
For a single drive network, the address must be set to 1.
For multiple drives, the addresses must be set sequentially starting from 1.
Index 2 : Baud Rate
Selects the baud rate and network type for the internal RS485 communication port.
When using the gateway, the baud rate must be set to 57.6kbps.
Index 3 : Communication loss protection
Defines the time for which the drive will operate without receiving a valid command telegram to Register 1 (Drive Control Word)
after the drive has been enabled. Setting 0 disables the Watchdog timer. Setting a value of 30, 100, 1000, or 3000 defines the time
limit in milliseconds for operation. A ‘ ’ suffix selects trip on loss of communication. An ‘ ’ suffix means that the drive will coast stop
(output immediately disabled) but will not trip.
