Official Troubleshooting Steps
Code type: Operator programming error Manual section: Yaskawa V1000 Troubleshooting The following simultaneous contradictory settings: - b5-15 not 0.0 (PID Sleep Function Operation Level) - The stopping method is set to either DC injection braking or coast to stop with a timer (b1-03 = 2 or 3). - Set b5-15 to a value other than 0. - Set the stopping method to coast to stop or ramp to stop (b1-03 = 0 or 1). - D control is being used on the setpoint deviation (b5-01 = 1) or on the feedback value (b5-01 = 2). - A negative PID output value is set to operate the drive in reverse (b5-11 = 1) and the frequency reference lower limit greater than 0 (d2-02 > 0). Set parameters b5-01, b5-11, and d2-02 to the proper values. - D control is being used on the setpoint deviation and the frequency reference plus the PID output (b5-01 = 4), D control is being used on the feedback value and the frequency reference plus the PID output (b5-01 = 4). - The frequency reference lower limit is set to a value greater than 0 (d2-02 > 0). Set parameters b5-01 and d2-02 to the proper values.
