Abnormally High Feedback Speed

What does SRVO-071 mean?

The feedback speed reported by the motor's Pulsecoder is abnormally high, exceeding expected operational limits. If this alarm occurs concurrently with the SRVO-064 (PHAL alarm), SRVO-064 is considered the primary cause.

• Axis moving at an unexpectedly high speed indicated by the pulsecoder feedback.
• External force causing rapid unintended axis movement.
• Incorrect servo motor command or velocity loop tuning.
• Pulsecoder generating erroneous high-speed feedback due to internal fault.
• Mechanical resonance causing rapid oscillation of the axis.

Click steps to track your progress.

1. 1

   Ensure the robot connection cable (RMP1, RP1) connector (CRF8) on the 6-Axis servo amplifier and the connector on the motor side are tightly connected.

2. 2

   Check that the shielding of the robot connection cable (RMP1, RP1) is securely grounded in the cabinet.

3. 3

   Replace the Pulsecoder.

4. 4

   Replace the servo amplifier.

5. 5

   Replace the robot connection cable (RMP1, RP1, RM1).

6. 6

   Replace the internal cable of the robot (for the Pulsecoder, or for the Motor).
