Yaskawa ∑ - II Servo Drive Debugging Guide

A. 83 Absolute Value Encoder Battery Error Battery voltage<2.7V Replace battery when powered on (ER6VC3 or JZSP-BA01)

A. CC multi cycle limit inconsistency SERVPCACK and encoder multi cycle setting are different. After modifying Pn205, execute Fn013

A. The d0 position error pulse overflow position gain is too low, the load inertia is large, and the pulse frequency is too high, increasing Pn102; Reduce the electronic gear ratio; Check the machinery

A. F1 power supply phase loss inspection, main power supply phase loss inspection, L1/L2/L3 wiring and MCCB

7.2 Alarm Reset

Press the RESET button on the numeric operator (while pressing UP+DOWN on the panel operator).

Through the CN1-44 (/ALM-RST) signal (low level active).

Partial alarms (A.02, A.04, A.81, A.82, etc.) require power outage and restart.

7.3 Troubleshooting of motor not rotating despite no alarm display

Check if/S-ON is at low level (servo enabled).

Check if P-OT/N-OT is at low level (operation is prohibited when overtravel is prohibited).

Check if the control power supply DC24V is normal.

Speed control mode: Check if there is voltage in V-REF; Position control mode: Check if PULS signal is input.

When using an absolute value encoder, the SEN signal must be at a high level (absolute data request).

Chapter 8: Maintenance and upkeep

8.1 Regular inspection items

Component cycle inspection content

Daily vibration, abnormal noise, and surface cleaning of the motor

The insulation resistance of the motor is measured annually with a 500V megohmmeter, and is ≥ 10M Ω (with SERVOPACK disconnected)

Oil seal replaced every 5000 hours

SERVOPACK cooling fan replacement in 4-5 years

Smooth capacitors should be checked for leakage and discoloration after 7-8 years, and replaced if necessary

Circuit board electrolytic capacitor 5-year test, replace circuit board if necessary

8.2 Absolute value encoder battery replacement

When an A.83 alarm occurs, the battery (model ER6VC3 or JZSP-BA01) must be replaced while the SERVOPACK control power supply is powered on. After replacement, turn off the power and then turn it back on to clear the alarm. If the battery is completely discharged and multiple cycles of data are lost, Fn008 needs to be executed to reset multiple cycles of data and reset the zero point.

8.3 Precautions for long-term discontinuation

If stored for a long time (more than 6 months), it is recommended to power on every six months to prevent the degradation of electrolytic capacitors.
