Page 100: Error Codes
Chapter 8 Troubleshoot the 8720MC-RPS Unit When an error occurs while the unit is stopped, the precharge operation and the PWM switching cannot be started by entering the RUN sequence signal, and thus, operation cannot be started until the error code is reset. When an error occurs during operation, the PWM switching stops, the discharge operation starts, and the unit stops. - Page 101 Troubleshoot the 8720MC-RPS Unit Chapter 8 Table 30 - Error Codes Common to All 8720MC-RPS Units Error Code Error Description Error Cause Corrective Action Check that the set value of the Precharge/ Discharge Time (F.014) is correct.
