    Wiring Main Circuit Terminals Wiring the Main Circuits This section describes wiring connections for the main circuit inputs and outputs. Wiring Main Circuit Inputs Observe the following precautions for wiring the main circuit power supply inputs. Installing a Molded-case Circuit Breaker Always connect the power input terminals (R, S, and T) and power supply via a molded-case circuit breaker (MCCB) suitable for the Inverter.
  • Page 52 Installing a Magnetic Contactor If the power supply for the main circuit is to be shut off during a sequence, a magnetic contactor can be used. When a magnetic contactor is installed on the primary side of the main circuit to forcibly stop the Inverter, however, the regenerative braking does not work and the Inverter will coast to a stop.

No general- purpose noise filter can effectively suppress noise generated from the Inverter.
  • Page 54 When using an magnetic contactor to switch to a commercial power supply, stop the Inverter and motor before operating the magnetic contactor. Use the speed search function if the magnetic contactor is operated during operation. If measures for momentary power interrupts are required, use a delayed release magnetic contactor. Installing a Thermal Overload Relay This Inverter has an electronic thermal protection function to protect the motor from overheating.
  • Page 55: Ground Wiring

    Wiring Main Circuit Terminals Countermeasures Against Radio Interference Radio noise is generated from the Inverter as well as from the input and output lines. To reduce radio noise, install noise filters on both input and output sides, and also install the Inverter in a totally enclosed steel box. The cable between the Inverter and the motor should be as short as possible.

The 5 modes and their primary functions are shown in the Table 3.3.

    Switching Modes The mode selection display will appear when the MENU Key is pressed from a monitor or setting display. Press the MENU Key from the mode selection display to switch between the modes. Press the DATA/ENTER Key from the mode selection key to monitor data and from a monitor display to access the setting display.
  • Page 84: Drive Mode

    Modes Drive Mode Drive mode is the mode in which the Inverter can be operated. The following monitor displays are possible in drive mode: The frequency reference, output frequency, output current, and output voltage, as well as fault information and the fault history. When b1-01 (Reference selection) is set to 0, the frequency can be changed from the frequency setting display.
  • Page 85: Quick Programming Mode

    Quick Programming Mode In quick programming mode, the constants required for Inverter trial operation can be monitored and set. Constants can be changed from the setting displays. Use the Increment, Decrement, and Shift/RESET Keys to change the frequency. The user constant will be written and the monitor display will be returned to when the DATA/ENTER Key is pressed after changing the setting.

    Modes Verify Mode Verify mode is used to display any constants that have been changed from their default settings in a program- ming mode or by autotuning. “None” will be displayed if no settings have been changed. Of the environment mode settings, only A1-02 will be displayed if it has been changed. Other environment modes settings will not be displayed even if they have been changed from their default settings.

    Always perform autotuning before starting operation. When V/f control has been selected, stationary autotuning for only line-to-line resistance can be selected. When the motor cannot be disconnected from the load, perform stationary autotuning. Contact your Yaskawa representatives to set motor constants by calculation.

    Applications with repetitive loads (cranes, elevators, presses, washing machines, etc.) using Inverters require derating for the repetitive load [reducing carrier frequency and current (changing accel/decel timing, increas- ing the frame size of the Inverter)]. Contact your Yaskawa representative for details. Initial Torque The startup and acceleration characteristics of the motor are restricted by the overload current ratings of the Inverter that is driving the motor.
  • Page 443: Installation

    Inverter Application Precautions Options Terminals B1, B2, 3 are for connecting only the options specifically provided by Yaskawa. Never connect any other devices to these terminals. 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 contam- inants, or install the Inverter in a completely enclosed panel.
  • Page 444 Wiring Check The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W. Check wring for any mistakes before supplying power. Check all wiring and sequences carefully. Magnetic Contactor Installation Do not start and stop operation frequently with a magnetic contactor installed on the power supply line. Doing so can cause the Inverter to malfunction.
  • Page 445: Motor Application Precautions

    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 made by Yaskawa. If 100% torque is required continuously at low speed, consider using a special Inverter or vector motor.
  • Page 446: Using The Inverter For Special Motors

    Noise Noise varies with the carrier frequency. At high carrier frequencies, the noise is almost the same when the motor is operated with a commercial power supply. Motor noise, however, becomes louder when the motor is operated at a speed higher than the rated speed. Using the Inverter for Special Motors Observe the following precautions when using a special motor.
