parameters, for replacing the firmware, for locating errors and for other
services. The physical standard used is RS232 (with accessory
HAS05.1-005 "RS232/RS485 converter", RS485 is possible, too).
Two protocols are supported for serial communication:
• ASCII-based protocol
• SIS protocol (Rexroth-standard serial binary protocol)
Note: The protocol is automatically recognized by the drive!
The following functions are made possible via the serial interface:
• reading and writing parameters via terminal or commissioning tool in
parallel with the existing master communication
• connecting a control terminal (BTV04)
• downloading firmware via the "IndraWorks D" program
The maximum baud rate is 115 kB.
General Information on the Parameter Structure
All parameters of the drive controller are stored in a uniform parameter
structure. Each parameter consists of 7 elements. The table below
describes the individual elements and the possibilities of access. The
following sections will also refer to the parameter structure below.
Element No. Data block element Possibility of access
1 IDN read
2 name read
3 attribute read
4 unit read
5 min. input value read
6 max. input value read
7 operating data read / write

Interface Mode
The serial interface can optionally be operated in the
• RS232 mode or
• RS485 mode.
Note: Communication via RS485 is only possible in conjunction with
an external RS232/RS485 converter (e.g. with accessory
module HAS05.1-005 by Bosch Rexroth).
Depending on the mode, it is necessary to use different cables
(see Project Planning Manual).
Transmission Protocols
Two different protocols are supported on the drive side:
• ASCII protocol
• SIS protocol
