Troubleshooting and maintenance of Siemens 840D system alarm 300502. Dihao Company repaired the industrial equipment of Ximenzi well and quickly. Our company's inventory of various series of Siemens accessories and maintenance required accessories, modules, capacitors, chips and other core accessories are all original and not easily damaged after repair. Many of them are scrapped after repair. If repairs are needed, they can be sent to our company for processing. Our company has complete online speedometers such as Siemens simulation testing platforms, and with a professional Siemens repair team, we can ensure the success rate of Siemens repairs. Our company has gained recognition from peers and Siemens users with reasonable prices and good reputation.;

Siemens 840D system alarm 300502 troubleshooting and maintenance: 300502 axis% 1 drive% 2 motor frequency converter phase current R error

Parameter:% 1=NC axis number

%2=Driver number

Explanation: The phase current R is greater than or equal to the maximum allowable power module current MD 1107 of Zui

1,05 times the limiting current of the transistor (MD-INVERTER_maX_CURRENT).

Reaction: BAG is not ready.

-The channel is not ready.

-This channel's NC startup is prohibited.

-NC stops when an alarm is triggered.

-Convert NC to tracking mode.

-Alarm display.

-Interface signal has been set.

Handling:

• Detect the current of Zui high-power module MD 1107 $MD-INVERTER_maX_CURRENT (limiting current of transistor)

Flow)

• Check engine data (engine code)

Engine grounding or inter turn short circuit

• Detect controller data

• Check the power module and engine terminals (including engine protection)

Error in collecting actual current values (replacing 611D power module or control module)
