6.6 Operator Programming ErrorsYASKAWA ELECTRIC SIEP C710616 27G YASKAWA AC Drive A1000 Technical Manual 359Troubleshooting6 Causes and Possible Solutions for a Blank and Unresponsive Digital OperatorTable 6.18 Causes and Possible Solutions for a Blank and Unresponsive Digital OperatorDigital Operator Display Error NameoPE11 Carrier Frequency Setting ErrorCorrect the setting for the carrier frequency.Cause Possible SolutionsThe following simultaneous contradictory settings: C6-05 is greater than 6 and C6-04 isgreater than C6-03 (carrier frequency lower limit is greater than the upper limit). If C6-05 isless than or equal to 6, the drive operates at C6-03. Correct the parameter settings.Upper and lower limits between C6-02 and C6-05 contradict each other.Digital Operator Display Error NameoPE13 Pulse Monitor Selection ErrorIncorrect setting of monitor selection for pulse train (H6-06).Cause Possible SolutionsScaling for the pulse train monitor is set to 0 (H6-07 = 0) while H6-06 is not set to 101, 102,105, or 116. Change scaling for the pulse train monitor or set H6-06 to 101, 102, 105, or 116.Digital Operator Display Error NameoPE15 Torque Control Setting ErrorParameters settings that are not allowed in combination with Torque Control have been set.Cause Possible SolutionsTorque Control in enabled (d5-01 = 1) while the Speed/Torque Control switch function isassigned to a digital input (H1- = 71).Correct the parameter settings.Either Torque Control is enabled by d5-01 = 1, the or Speed/Torque Control switch is assignedto a digital input H1- = 71, while at the same time:• Feed Forward is enabled (n5-01 = 1), or• Droop Control is enabled (b7-01 0), or• Intelligent Stall Prevention or Intelligent Stall Prevention 2 is enabled (L3-04 = 2 or 5), or• A digital input is set for the power KEB 1 or KEB 2 (H1- = 7A or 7B)Digital Operator Display Error NameoPE16 Energy Savings Constants ErrorCause Possible SolutionsIn AOLV/PM the automatically calculated energy saving coefficients are out of the allowablerange. Check and correct the motor data in E5 parameters.Digital Operator Display Error NameoPE18 Online Tuning Parameter Setting ErrorParameters that control Online Tuning are not set correctly.Cause Possible SolutionsOne of the following setting errors has occurred while Online Tuning is enabled in OLV(A1-02 = 2):• E2-02 has been set below 30% of the original default value• E2-06 has been set below 50% of the original default value• E2-03 = 0Make sure E2-02, E2-03, and E2-06 are set the correct values.Digital Operator Display Error NameoPE20 PG-F3 Setting ErrorThe encoder signal frequency is too high.Cause Possible SolutionsWith the entered encoder resolution (F1-01), maximum output frequency (E1-04), and motorpole number (E5-04,) the calculation encoder signal frequency exceeds 50 kHz (with PG-F3option).• Set F1-01 to the correct encoder resolution.• Reduce the maximum output frequency of the drive in parameter E1-04 so the encodersignal frequency at maximum speed is lower than 50 kHz.Cause Possible SolutionsA short circuit between +V, -V, and AC terminals. Correct wiringControl circuit terminal overload. Check the resistance and wiring for the frequency setting potentiometer, etc.Check that the current for terminals +V and -V is 20 mA or less.The short circuit bar between terminals +1 and +2 in the main circuit has been removed. Attach the short circuit bar.Braking unit terminals P and N are connected in reverse.• Check the Braking unit wiring including cables connected to the Braking unit and relayterminals.• Replace the drive.Control power circuit failureCharge indicator is lit:• Replace the digital operator• Replace the drive control board.Charge indicator is not lit:• Check the input power supply voltage• Replace the drive.Malfunction occurred in the control power circuit. Turn OFF the power, wait for 5 minutes, then turn ON the power again.Digital operator contact failure Turn OFF the power, remove the digital operator, then replace the digital operator.
