Frequently Asked Questions about 7VEXD033DC01
What does the diagnostic readout 010011 mean?
The diagnostic readout 010011 has a fault number FL19 and a fault name OVERV which means an excessive armature voltage (L, T).
-The ADR080-CMFLM is set too low.
-The drive is unstable.
-There is a VFB circuit failure- check test point VFB.
What does the diagnostic readout 010100 mean?
The diagnostic readout 010100 has a fault number of FL20 and a fault name TLOSS which means a loss of tach feedback (L, T).
-The tach leads are disconnected.
-There is a tach feedback circuit failure, the 7PL is disconnected or damaged.
-The Process Interface card jumpers or switches are incorrect.
-The P7-SFB ZERO on the Process Interface card is misadjusted - set test point SFBB for zero volts and zero speed.
-The AN or digital tach is connected but the CEMF regulator is being used - remove JP7 from the Process Interface card.
-JP17 on the Control card is in the 1-2 position. Move to the 2-3 position.
What does the diagnostic readout 010101 mean?
The diagnostic readout 010101 has a fault number of FL21 and a fault name of NCTRP and means there is a trip from the N.C. interlock on the Application card (L, T).
-There is an external input on 4TB7 (13PL-7).
-The Application card is absent but was selected by a soft jumper, check ADR010-APPJP.
What does the diagnostic readout 010110 mean?
The diagnostic readout 010110 has a fault number FL22 and a fault name PHLOS which means an AC phase loss (L, T).
-The JP14 on the Control card is in the wrong position.
-A fuse is open on the AC line -FU1-3.
-The 1PL is disconnected or damaged.
-There is a low or unbalanced AC line voltage - line to line or line to neutral is more than 5%low.
-There is a loose AC power connection.
The CFU1 on the Power Supply card is open.
-15-volt supplies are outside the limits (+ or - 5%).
