<strong>Siemens</strong> telegram 352, PZD 6/6<br />

The standard control (control word, frequency setpoint etc.)<br />

of SINAMICS G120 is implemented using the <strong>Siemens</strong> telegram.<br />

In SINAMICS G120, instead of telegram 352 (fixed assignment<br />

of the control/feedback signal words), telegram 999 is used<br />

(free assignment of the control/feedback signal words).<br />

In this case, in SINAMICS G120, to start, telegram type 350<br />

should be selected in parameter p922. This pre-assigns the<br />

BICO connections. Telegram type 999 (free interconnection<br />

via BICO) should then be selected and the following interconnections<br />

made:<br />

■ p2051[4] = r2131 (error number)<br />

■ p2051[5] = r2110 (alarm number)<br />
