Maintenance to the DRV25 internal mechanism is
required. DRV25 continues to operate safely, but with
reduced performance. Check for the following:
• Motor damage or signs of wear
• Proportioning Assembly damage or signs of wear
• Debris in the Drive Assembly
If this mode is not addressed then it is likely the DRV25
will stop working and develop into a critical motor error.
The following symptoms indicate motor / cable loom
failure or a malfunction of the positioning sensor. In the
first instance, power cycle/reboot the DRV25. If the error
persists, check for the following:
• Internal PCBA connectors to DRV25 are
disconnected, damaged or possibly wet
• Dirt or debris around motor
• Motor is disconnected
• Opto encoder is not coupled to the motor
• Proportioning Assembly is sticking or has seized
• Motor is loose
• Drive belt is loose or dislodged
