Caution
Do not touch the inside of the Inverter. Doing so may result in electric shock or
injury.
Wiring or inspection must be performed only after turning OFF the power sup-
ply, confirming that the CHARGE indicator (or status indicator) is OFF and
after waiting for the time specified on the front cover. Not doing so may result
in electrical shock.
Do not damage, pull on, apply stress to, place heavy objects on or pinch the
cables. Doing so may result in electrical shock.
Do not touch the rotating parts of the motor under operation. Doing so may
result in injury.
Do not modify the product. Doing so may result in injury or damage to the
product.
Do not store, install or operate the product in the following places. Doing so
may result in electrical shock, fire or damage to the product.

  • Page 146: Using Highslip Braking

    ‹ Using Highslip braking When the system is operating, the Inverter is delivering an amount of electrical energy to the motor, this energy is transformed into mechanical and thermal energy. As a generator, the motor efficiency is still high. Most of the energy returns to the Inverter as current flow. This regenerated current is stored in the DC bus capacitors, increasing the DC bus voltage.
  • Page 147 Stopping Methods „ The concept of HSB If we want to stop very fast without using a braking resistor, the only way is to reduce the amount of current regeneration. This is done by reducing the motor efficiency. Most of the energy will be dissipated as heat within the motor and just a little bit of energy is regenerated to the Inverter.

  • Page 148: Using An Emergency Stop

    3. This step is not always necessary. If step 2 is not sufficient enough to stop the motor and the DC volt- • age increases again, the inverter takes an other action similar like step 2. After these steps the inverter runs during 1.5s at minimum speed and decellerates to zero following the pro- grammed ramp.

    Although the Inverter's protective functions will stop operation when a fault occurs, the motor will not stop immediately. Always provide mechanical stop and protection mechanisms on equipment requiring an emer- gency stop. „ Options Terminals 3 are for connecting only the options specifically provided by OMRON. Never connect any other devices to these terminals.

    Inverter Application Precautions ‹ Installation Observe the following precautions when installing an Inverter. „ Installation in Enclosures Either install the Inverter in a clean location not subject to oil mist, air-bourne matter, dust and other contami- nants or install the Inverter in a completely enclosed panel. Provide cooling measures and sufficient panel space so that the temperature surrounding the Inverter does not go beyond the allowable temperature.

    Cooling effects diminish in the low-speed range, resulting in an increase in the motor temperature. Therefore, the motor torque should be reduced in the low-speed range whenever using a motor not mabe by OMRON. If 100% torque is required continuously at low speed, consider using a special inverter or vector motor.

    ‹ Using the Inverter for Special Motors Observe the following precautions when using a special motor. „ Pole-changing Motor The rated input current of pole-changing motors differs from that of standard motors. Select, therefore, an appropriate Inverter according to the maximum input current of the motor to be used. Before changing the number of poles, always make sure that the motor has stopped.
