4-16 Master Communication MPH-02, MPB-02, MPD-02

DOK-INDRV*-MP*-02VRS**-FK01-EN-P

Note: The bits in the signal control word are processed in every

interface cycle at the point of time defined in the S-0-0008,

Command value valid time (T3) parameter.

This functionality can be used, for example,

• for freely configuring the digital inputs

• for setting-up mode via digital inputs

• for setting bits in drive parameters and for starting commands via the

cyclic channel (master communication)

Note: For SERCOS and field bus interface the S-0-0145, Signal

control word parameter must be accordingly configured in

the cyclic data so that the configure control bits are evaluated.

• S-0-0027, Configuration list signal control word

• S-0-0145, Signal control word

• S-0-0329, Assign list signal control word

• S-0-0399, IDN list of configurable data in the signal control word

Notes on Commissioning the Signal Control Word

Only parameters contained in S-0-0399, IDN list of configurable data in

the signal control word can be assigned to the S-0-0027,

Configuration list signal control word parameter.

In the S-0-0027, Configuration list signal control word parameter the

IDNs of those parameters are indicated that are to be configured by

means of the signal control word (= targets).

The position of an IDN in this list defines which bit is assigned to which

IDN (targets) in the signal control word. For example, the 1

list element

determines the parameter to which bit 0 of the signal control word is

assigned.

Which bit of the selected parameters (= targets in parameter S-0-0027) is

set (or cleared) by the signal control word, has to be defined in parameter

S-0-0329, Assign list signal control word.

Note: If this list remains empty, bit 0 of the mentioned parameters is

automatically influenced. Otherwise the bit that is to be

assigned to the target parameter is entered in this list.

Bit numbers from "0" (LSB) to "31" (MSB) can be entered.

• If the assigned parameter is a command, the bit number in the

S-0-0329, Assign list signal control word parameter is irrelevant.

• If the parameter assigned is parameter S-0-0346, Positioning

command strobe, a positive edge in the respective bit of the control

word causes toggling of parameter S-0-0346.

Note: A maximum of 16 bits can be configured. Configuration must

always be carried out from the least significant to the most

significant bit; in other words, the position of the bit copy in the

signal control word results from the continuous configuration in

parameter S-0-0027, Configuration list signal control word.
