Cybex 525T Treadmill Part Number
Error 7: Controller Fold-back
Cause:
The motor is bogging down, which causes high current. Once a threshold current is met, the drive begins
to fold-back the actual frequency in response to the motor slip in order to prevent a complete motor stall.
Once the over-current condition goes away, normal operation resumes. If the over-current remains, the
display will sound a triple-beep, and lower the Target Speed to the reported new Target of the drive.
NOTE: This scenario can repeat if necessary.
Service:
Error 7 is typically caused by a Super-User and/or worn belt and deck. This is a normal condition and
the error is stored for tracking purposes only. If it repeats often, verify line voltage isn't sagging.
• Check the belt/deck for wear.
• Check treadmill for physical obstructions, seized bearings, etc.
• Investigate actual line current with various weight users. Determine user weight, speed and incline
when error occurred.
