Communications via RS485 Interface
Transmission Protocols
DOK-ECODR3-FL*-04VRS**-FK01-EN-P
Features
Communication via the RS485 interface makes it possible to implement a
serial bus with the following data:
• Up to 8 drives can be connected to one bus master.
• Transmission rates of:
• Maximum transmission path: 500m
• Half duplex mode over a 2-wire line
• 8-bit ASCII protocol or 8-bit SIS protocol
• Parity bit: none, even, odd
• one stop bit

When the 24V supply voltage is switched on, the data set in Parameters
B001, B002, B009 and B010 are used as the communications
parameters. If these settings do not correspond to the data in the
programming unit, the S1 button on the programming module can be
used to set the default transmission parameters. See also: "Initial Startup"
