Note: The data for the field bus status word refer to the I/O mode

with block acknowledgment (default configuration).

Notes on Parameterization/Commissioning

The following settings are made in the I/O mode as default setting:

• Fixed real-time channel length of 2 bytes. Thus the length of the cyclic

data channel is (P-0-4082 = P-0-4071 = 2)!

• Bits 0...5 of P-0-4051, Positioning block acknowledgment are

copied to bits 8...13 of S-0-0144, Signal status word.

• In the real-time channel only P-0-4068, Field bus: control word IO

and S-0-0144, Signal status word are transmitted.

Note: With this profile selection, the functional compatibility to the

DKC3.1 drive controllers is established!

Control units that process the real-time data in Motorola format

have the high byte and low byte interchanged compared to the

DKC3.1!

There are the following possibilities for free configuration/expansion:

• The user can freely expand the length of cyclic data channel P-0-4082

or P-0-4071 up to a maximum of 9 words. Apart from the control and

status word, further real-time data can be configured via the

parameters P-0-4080, Field bus: config. list of cyclic actual value

data ch. and P-0-4081, Field bus: config. list of cyclic command

value data ch..

• The content of S-0-0144, Signal status word can be freely

parameterized via S-0-0026, Configuration list signal status word

and S-0-0328, Assign list signal status word.

Freely Configurable Mode (Rexroth Profile Type)

Brief Description

To use the extensive and numerous functions of a Rexroth drive with field

bus interface it is necessary, in addition to the I/O mode (downwards

compatible to the DKC3.1), to define another profile, the freely

configurable mode. This implies the use of a new controls and status

word (P-0-4077, Field bus: control word and P-0-4078, Field bus:

status word).

• The structure (content) of the real-time data channel must be defined

via the configuration parameters P-0-4080 and P-0-4081. No profile-

dependent settings and checks are carried out!

• In this profile type the Rexroth-specific definitions for the field bus

control and status words apply. Some bits in the parameters P-0-4077,

Field bus: control word and P-0-4078, Field bus: status word can

only be used in conjunction with certain operating modes.

• This profile type allows using the entire drive functionalities (e.g.

velocity synchronization, drive-controlled positioning, ...).

• The primary and secondary modes of operation can be freely selected

via S-0-0032, S-0-0033, S-0-0034 and S-0-0035.
