Siemens 400 V / 210...590 A Checking actual value acquisition and precharging

01.2004 Basic Function Check

Checking actual value acquisition and precharging

Issue the ON command via PMU (by default, ON command P554 already set on PMU)

♦Reaction: Precharging begins with picking up of the contactor -K4, and the DC link voltage (see display parameter r006) rises within approximately 1 second to the final value, approximately 1.35 times the mains voltage. The main contactor -K1 is connected once the final value has been reached.

♦Contacts: cf. section entitled "Control connections"

Main contactor ON command from CUSA X100 terminal 6 (M24)-7 signal from normally-open CUSA binary output 2

This command is forwarded to the mains angle acquisition circuit

VSB: connector X3: terminal 5 signal X3: terminal 1 M24

Output to potential-free contact VSB: X2 terminal 1: 230 V AC

X2 terminal 3: to coil of main contactor -K1

♦Reaction: Once the main contactor -K1 has picked up, the precharging contactor -K4 opens after approx. 500 ms.

♦ Status: 0011 "Ready to Run"

The AFE inverter is now in the "Ready to Run " state and the following actual values must be correctly displayed: r032: Mains frequency tolerance ± 2 %

r030: Mains voltage, currently applied RMS value tolerance ± 2 %

If the fault F004 occurs, check the mains direction of rotation, check the main contactor's contacts and check the mains voltage.
