There are indicators on the upper left of the RUN and STOP Keys on the Digital Operator. These indicators will light and flash to indicate operating status. The RUN Key indicator will flash and the STOP Key indicator will light during initial excitation of the dynamic brake.
Modes Modes This section describes the Inverter's modes and switching between modes. Inverter Modes The Inverter's user parameters and monitoring functions are organized in groups called modes that make it easier to read and set user parameters.The Inverter is equipped with 5 modes. The 5 modes and their primary functions are shown in the Table 3.2.
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 ENTER key from the mode selection key to monitor data and from a monitor display to access the setting display.
Page 71
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 dis- play.
Page 72
Quick Programming Mode In quick programming mode, the parameters required for Inverter trial operation can be monitored and set. parameters can be changed from the setting displays. Use the Increment, Decrement and Digit Selection/ RESET keys to change the frequency. The user parameter will be written and the monitor display will be returned to when the ENTER key is pressed after changing the setting.

Modes Verify Mode Verify mode is used to display any parameters that have been changed from their default settings in a pro- gramming mode or by autotuning. “None” will be displayed if no settings have been changed. Even in verify mode, the same procedures can be used to change settings as they are used in the programming modes.
Page 76
Autotuning Mode Autotuning automatically tunes and sets the required motor parameters. Always perform autotuning before starting operation. When the motor can not be disconnected from the load, perform stationary autotuning. Contact your dealer to set motorparameters by calculation. The Inverter’s autotuning function automatically determines the motor parameters, while a servo system’s autotuning function determines the size of a load, so these autotunig functions are fundamentally different.

Stopping Methods Selecting the Stopping Method when a Stop Command is Input There are four methods of stopping the Inverter when a stop command is input: • Deceleration to stop • Coast to stop DC braking stop • Coast to stop with timer •...
Page 149
Stopping Methods Deceleration to Stop If the stop command is input (i.e., the run command is turned OFF) when b1-03 is set to 0, the motor deceler- ates to a stop according to the deceleration time that has been set. (Factory setting: C1-02 (Deceleration Time If the output frequency when decelerating to a stop falls below b2-01, the DC injection brake will be applied using the DC current set in b2-02 only for the time set in b2-04.
Page 150
DC Braking Stop After the stop command is input and the minimum baseblock time (L2-03) is elapsed, DC injection will be applied to the motor. The applied DC injection current is programmed in parameter b2-02. The DC injection brake time is determined by the set value in b2-04 and the output frequency when the stop command is input. DC injection brake time Run command b2-04 x 10...
Stopping Methods Using the DC Injection Brake Set parameter b2-03 to apply DC injection to the motor, before it starts to accelerate. Applying DC injection at start will stop the motor before starting, if it was coasting through inertia or wind mill effect. Set b2-03 to 0 to disable the DC injection brake at start.
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. When the motor is operating as a generator, the motor efficiency is still high. Most of the energy returns to the Inverter as current flow.
Page 153
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.
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.
Acceleration and Deceleration Characteristics Acceleration and Deceleration Characteristics Setting Acceleration and Deceleration Times Acceleration time indicates the time to increase the output frequency from 0Hz to the maximum output fre- quency (E1-04). Deceleration time indicates the time to decrease the output frequency from max. frequency to 0Hz (E1-04).
Page 156
Switching Acceleration and Deceleration Time Automatically Use this setting when you want to switch acceleration/deceleration time automatically using the output fre- quency. When the output frequency reaches the set value in C1-11, the Inverter switches the acceleration/deceleration time automatically as shown in the following diagram. Set C1-11 to a value other than 0.0 Hz.
Page 157
Acceleration and Deceleration Characteristics Preventing the Motor from Stalling During Acceleration (Stall Prevention During Acceleration Function) The Stall Prevention During Acceleration function prevents the motor from stalling if a heavy load is applied to the motor or sudden rapid acceleration is performed. If you set L3-01 to 1 (enabled) and the Inverter output current exceeds the -15% level of the set value in L3- 02, the acceleration rate will begin to slow down.

Communications Functions Self-Diagnosis The Inverter has a built-in function for self-diagnosing the operations of serial communications interface cir- cuits. This function is called the self-diagnosis function. The self-diagnosis function connects the communica- tions parts of the send and receive terminals, receives the data sent by the Inverter, and checks if communications are being performed normally.

The operation method selection is wrong. If parameter b1-02 (reference selection) is set to 0 (Digital Operator), the motor will not operate when an external operation signal is input. Set b1-02 to 1 (control circuit terminal) and try again. Similarly, the motor will also not operate if the LOCAL/REMOTE key has been pressed to switch to Digital Operator operation.

If the Vertical-axis Load Drops When Brake is Applied The sequence is incorrect. The Inverter goes into DC injection braking status for 0.5 seconds after deceleration is completed. (This is the factory-set default.) To ensure that the brake holds, set frequency detection 2 (H2-01 = 5) for the multi-function contact output ter- minals (M1 and M2) so that the contacts will turn OFF when the output frequency is greater than L4-01 (3.0 to 5.0 Hz).
Page 273
Troubleshooting If the Ground Fault Interrupter Operates When the Inverter is Run The Inverter performs internal switching, so there is a certain amount of leakage current. This may cause the ground fault interrupter to operate and cut off the power supply. Change to a ground fault interrupter with a high leakage detection level (i.e., a sensitivity current of 200 mA or greater per Unit, with an operating time of 0.1 s or more) or one that incorporates high frequency countermeasures (i.e., one designed for use with Invert- ers).

If OV is Detected When a Fan is Started or Fan Stalls Generation of OV (Over Voltage) and stalling can occur if a fan is turning when it is started.

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.

Handling Observe the following precautions when wiring or performing maintenance for an Inverter. Wiring Check The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V or W. Check wiring 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.
Installation Withstand Voltage If the input voltage is high (440 V or higher) or the wiring distance is long, the motor insulation voltage must be considered. Contact your OMRON representative for details. High-speed Operation When using the motor at a high speed (50 Hz or more), problems may arise in dynamic balance and bearing durability.

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.
