The AC MCB (Motor Control Board) monitors the drive system and reports any anomalies by 
triggering what is called a DFR (Drive Fault Record) code.   

 
The AC System has the same codes as the DC system but the meanings may not necessarily be the 
same, specifically “CHECK SPEED SYSTEM” and “CHECK MOTOR SYSTEM”. You must now take 
in to account that the MCB may have issued a DFR code which has shut the treadmill down and 
display one of the “CHECK” codes. In most cases you will find that a DFR code has been flagged and 
caused the unit to shut down.  

 
There are two ways to check to see if a DFR code has been captured: 
 

1.  Check the LAST ERROR LIST in the Maintenance Mode 

x  Engage the Maintenance Mode and access the LAST ERROR LIST  

x  Scroll the parameters until you come to the LAST DFR 

x  There will be an 8 digit number that is the DFR code 

Example:  LAST DFR(X) 00004000 (over temp on motor or drive). 

o  Ignore the first set of zero’s before the number.  This example will be 

considered a 4000 code 

o  If the Last DFR list reads LAST DFR(X)00000000, a DFR has not been 

recorded by the MCB and reported to the display.  Follow the appropriate 
troubleshooting steps for the code displayed (i.e. ELEVATION STALL, etc.) 

 

2.  Count the blinks from the Status led’s on the MCB 

x  When the MCB records a DFR, the three Status 

led’s (Led 1, Led 2 and Led 3) will blink together 
simultaneously 

x  The Status led’s will blink the number of times 

that indicate the particular DFR code 

x  There will be a short pause in the blinking to 

show counting separation (Count the blinks 
between the pauses) 
Example:  Count 15 blinks, pause, 15 blinks 
again would indicate a 4000 DFR code, which is 
an “over temp on motor or drive”
