官方故障排除步驟
Message value: Drive object: A_INF, S_INF Reaction: NONE Acknowledge: NONE Cause: The DC link voltage setpoint has reached the ma ximum steady-state voltage parameterized in p0280. The DC link voltage is increased by the modulation d epth reserve controller for the following reasons: - modulation depth reserve is too low (p3480). - line supply voltage is too high. - supply voltage (p0210) parameterized to be too low. - excessively high setpoint fo r the reactive line current. Remedy: - check the line supply voltage setting (p0210). - check the line supply for an overvoltage condition. - reduce the modulation depth reserve (p3480). - reduce the reactive current setpoint.
