(Wiring is the responsibility of the user. Never touch the output terminals directly with your hands or allow the output lines to come into con tact with the Inverter case. Never short the output circuits Otherwise. an clcctric shock or ground short can occur If the power supply is turned on during the FWD(or REV) Run Command is given, the motor will start automaticall Turn the power supply oN after verifying that the run signal is OFF Failure to observe this warning may rcsult in injury When the 3-wire sequence is set, do not make the wiring for the control circuit unless the multi function input terminal constant is set Failure to observe this warning may result in injury ∧ CAUTION Check to be sure that the voltage of the main ac power supply satisfies the rated voltage of the Injury or fire can occur if the voltage is not correct Do not perform voltage withstand tests on the Inverter Connect braking resistors, Braking Resistor Units, and Braking Units as shown in the l/O wiring examples Otherwise, a firc can occur and the Invcrtcr, braking resistors, Braking Resistor Units, and Braking Units can bc damagcd CAUTION ighten all terminal screws to the specified tightening torque Otherwise, a fire may occur Do not connect Ac power to output terminals U, V, and W. The interior parts of the Inverter will be damaged if voltage is applied to the output terminals Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits The Inverter can be damaged or interior parts burnt if these devices are connected Do not connect magnetic contactors to the output circuits If a load is connected while the Inverter is operating, surge current will cause the overcurrent protection circuit inside the o operat Setting User Constants A CAUTION Disconnect the load(machine, device) from the motor before performing rotational autotuning The motor may turn, possibly resulting in injury or damage to equipment. Also, motor constants cannot be correctly set with the motor attached to a load Stay clear of the motor during rotational autotuning The motor repeats running and stopping until autotuning has been completed, possibly resulting in injury In stationary autotuning 1, when the motor is first operated in the drive mode after tuning, the remaining motor constants E2-02 (Motor rated slip)and E2-03(Motor no-load current) are set auto matically. To perform an operation immediately after stationary autotuning 1, use the following pro- cedure under the recommended conditions (1) Check the values of E2-02 and E2-03 in verify mode or advanced programming mode (2)Run the motor once in drive mode under the following conditions The Inverter and the motor are connected The motor shaft is not locked with a mechanical brake or other stopping mechanism(or function) A motor-load ratio of 30% or less is maintained A speed of 30% or more of the base frequency set at E1-06 ( default= highest frequency) is maintained at a constant speed for one second or more (3)After stopping the motor, check the values of E2-02 and E2-03 again in verify mode or advanced program- ming mode. If the values of E2-02 and E2-03 differ from the ones before the first operation was carried out, the settings have been successfully completed. Next, check if the values are suitable or not If the values of E2-02 and E2-03 differed greatly from the reference data of the motor in the test report or the instruction manual(TOE-S616-60.1), hunting, motor vibrations, insufficient motor torque, or an overcurrent may occur because the motor is operated although the aforementioned conditions have not been fulfilled after stationary autotuning 1. For eleva- In stationary autotuning I again and run the motor using the aforementioned procedure under the recommended conditions or perform stationary autotuning 2 lational autoly Usually the standard setting for E2-02 is I Hz to 3 HZ, and that for E2-03 is 30% to 65%o of the rated current for a general purpose motor. Generally, the larger the motor capacity is, the smaller the rated slip and the ratio of the no-load current to the rated current become. Use the data given in Factory Settings that Change with the Inverter Capacity 102-04)of Chap ter 5 User Constants as a reference Trial operation A WARNING Check to be sure that the front cover is attached before turning on the power supply An electric shock may occur Do not come close to the machine when the fault reset function is used if the alarmed is cleared the machine may start moving suddenly Al the machine so that human safety is ensured even when it is restarted Injury may occur Provide a separate emergency stop switch; the Digital Operator STOP Key is valid only when its function is set Injury may occur A WARNING Reset alarms only after confirming that the run signal is OFF. Injury may occur A CAUTION Dont touch the radiation fins(heatsink), braking resistor, or Braking Resistor Unit. These can become very hot Otherwise, a hurn injury may occur.
