4.2 Alarm and fault messages

Table 4-11 Fault 39

(Alarm) DC link overvoltage

 

Condition

The CU has detected a DC voltage in excess of the

 

 

permissible value

 

 

 

 

Causes

The measured DC voltage is too high

 

 

o The available DC voltage is too high

 

 

The PV field has been connected

 

 

incorrectly (the voltage rises too sharply at

 

 

high temperatures, mostly under no load)

 

 

o DC voltage measurement error

 

 

Parameter setting error (CU software)

 

 

Power pack defective (measured-value

 

 

sensing)

 

 

 

 

Measures

Adjust the parameter settings

 

 

Replace the power pack

 

 

Change the connection and/or the cabling of the PV field

 

 

Connect a braking resistor

Table 4-12 Fault 40

(Alarm) Fast Stop 2; Fast Stop via customer terminal block

Condition There is no signal at input 11/12 of the CU (green connector); transferred via Profibus to the S7; drive has not received an ON command.

Causes

No line voltage for Fast OFF

 

o Fast Stop button has been pressed

 

o Wire break in the Fast OFF circuit

 

o No power supply for Fast OFF

 

o Fire alarm system has been activated (if

 

installed)

 

o No jumper on terminal strip X50 (if no Fast

 

Stop button is connected)

 

 

Measures

Unlock the Fast Stop button.

 

Repair the cabling
