Consult with Yaskawa before attempting to use a motor other than the model specified a Confirmations upon Delivery A CAUTION Never install an Inverter that is damaged or missing components Doing so can result in injury Installation /! CAUTION Always hold the case when carrying the Inverter Attach the Inverter to a metal or other noncombustible matera ossibly resulting in injury If the Inverter is held by the front cover, the main body of the Inverter may fall Fire can result if the inverter is attached to a combustible material Install a cooling fan or other cooling device when installing more than one Inverter in the same enclosure so that the temperature of the air entering the Inverters is below 45XC Overheating can result in fires or other accidents ■ Wiring △ WARNING Always turn OFF the input power supply before wiring terminals Otherwise. an electric shock or fire can occur Wiring must be performed by an authorized person qualified in electrical work electric shock or fil Be sure to ground the ground terminal (200 V Class: Ground to 100 Q2 or less, 400 V Class Ground to 10 q or less Always check the operation of any fast stop circuits after they are wired Othcrwisc, thcrc is the possibility of injury. (Wiring is thc responsibility of thc uscr. 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 electric shock or ground short can occur Do not use the Inverter for any load other than a three-phase Ac motor A permanent magnet motor is a type of permanent magnet motor with a rotor in which a magnet is integrated. Unlike an induction motor, the permanent magnet motor terminal generates high volt age when the motor is running, even when the Inverter power is shut off. Be sure to completely stop the motor before wiring, maintenance and inspection failure to do so may result in electric shock A WARNING Wire the Inverter so that the Run command switches off when a Stop command (or Fast stop com mand)is input to terminal BB or terminal BB1 If the run command is not removed then the motor will begin running as soon as the stop com mand (or Fast stop command)is cleared This can result in personal injury CAUTION Check to be sure that the voltage of the main ac power supply satisfies the rated voltage of the Inverter Injury or fire can occur if the voltage is not correct. Do not perform voltage withstand tests on the Inverter Otherwise, semiconductor elements and other devices can he damaged Connect braking resistors, Braking Resistor Units, and Braking Units as shown in the l/o wiring Otherwise, a firc can occur and the Invcrtcr, braking resistors, Braking Resistor Units, and Braking Units can bc damagcd Tighten all terminal screws to the specified tightening torque Otherwise, a firc may occur. Do not connect AC power to output terminals U, V, and W. Thc intcrior parts of the Invcrtcr will bc damaged if voltage is applicd to thc 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 When a magnetic contactor is connected to the output circuits do not switch it on and OFF while Surge current will cause the overcurrent protection circuit inside the Inverter to operate This Inverter can drive an induction motor or a permanent magnet motor. Select a suitable control method(parameter A1-02 )for the motor you drive Failure lo do so will cause darnage to the molor Setting User Parameters / WARNING Do not change the factory setting(0)in b1-03(Run Command source selection) Doing so can causc thc elevator to drop Do not change the factory setting(1)in L8-05 (Input open-phase protection selection) You can change it to O, but only after confirming that there are no factors that cause input open phase Doing so may damage the Inverter main circuits /! CAUTION Disconnect the load (machine, device) from the motor before performing rotational autotuning or pole tuning The motor may turn, possibly resulting in injury or damage to equipment. Also, motor parameters cannot be correctly set with thc motor attached to a load Stay clear of the motor until rotational autotuning or pole tuning has been successfully completed The motor could stop and then start again unexpectedly and this could rcsult in injury Always confirm the following before rotational autotuning or pole tuning The lock key has been removed from the motor shaft There are neither people nor objects around the motor shaft. The motor is at a complete stop Failure to do so may result in injury Be careful when handling the shaft and coupling Failure to do so may result in injury. Be careful not to injure yourself with the key groove when turning the motor shaft by hand Failure to do so may result in injury When operating a permanent magnet motor for the first time, or after exchanging a permanent magnet motor or an Inverter, set a correct motor parameter to the inverter before the operation and be sure to check the motor speed detection Shortage of torque may be the cause when the motor is pulled in the load direction or when the motor does not run as directed such as reverses. doesn't work. or over-accelerates Refer to Chapter 4 Trial Operation for details Do not change the parameter settings unnecessarily Doing so may impede motor operation When running a permanent magnet motor, be sure to set the following parameters Motor related parameters(E1-日日,E5-口) Parameters for Pg open- circuit detection function(F1-oo Parameters for excessive speed deviation detection function(F1-o0) Parameters for over-acceleration detection function (S3-ao) Failure lo du ill If running a permanent magnet motor with any option cards other than the PG-F2 card, and not using the braking sequence recommended by this Ir set the following braking sequer After inputting the operational order, or closing the pole detection complete signal, release the braking A basket will be pulled by a counter weighl.
