Application and Overload Selections Carrier Frequency and Inverter Overload Capability The inverter overload capability depends among other things on the carrier frequency setting. If the carrier frequency setting is higher than the factory setting, the overload current capability must be reduced. Heavy Duty (C6-01=0) The default carrier frequency for the Heavy Duty mode is 2 kHz.
Page 184
Normal Duty 1 (C6-01=1) The default carrier frequency for the Normal Duty 1 mode depends on the inverter capacity. The overload capability is 120% of the Normal Duty 1 rated current for 1 minute. If the carrier frequency is set to a higher value than the factory setting, the overload capabilty is reduced like shown in Fig 6.3.

2-Step Switching: Master/Auxiliary If performing 2-step switching between master and auxiliary speed frequencies, input the master speed fre- quency reference to control circuit terminal A1, and input the auxiliary speed frequency reference to A2. When terminal S3 (multi-step speed command 1) is OFF, terminal A1 input (master speed frequency refer- ence) will be the Inverter frequency reference, and when terminal S3 is ON, terminal A2 input (auxiliary speed frequency reference) will be the Inverter frequency reference.
Page 187
Frequency Reference Setting Frequency Reference Using Pulse Train Signals When b1-01 is set to 4, the pulse train input signal at terminal RP input is used as the frequency reference. Set H6-01 (PulseTrain Input Function Selection) to 0 (frequency reference), and then set the reference pulse frequency that is equal to 100% of the reference value to H6-02 (Pulse Train Input Scaling).
Using Multi-Step Speed Operation The inverter supports a multi step speed operation with a maximum of 17 speed steps, using 16 multi-step fre- quency references, and one jog frequency reference. The following example of a multi-function input terminal function shows a 9-step operation using multi-step references 1 to 3 and jog frequency selection functions.
Page 189
Frequency Reference Setting Precautions When setting analog inputs to step 1 and step 2, observe the following precautions. When setting terminal A1's analog input to step 1 set b1-01 to 1, when setting d1-01 (Frequency Reference • 1) to step 1 set b1-01 to 0. When setting terminal A2's analog input to step 2 set H3-09 to 2 (auxiliary frequency reference).

DC Braking to Stop (b1-03=2) After the stop command has been input and the minimum baseblock time (L2-03) has elapsed, DC injection will be applied to the motor. The applied DC injection current can be set in parameter b2-02. The DC injection braking time depends on the set value of b2-04 and on the output frequency at the moment the stop command is input.
Stopping Methods Using the DC Injection Brake The DC injection brake can be used to stop a coasting motor before restarting it or to hold it at the deceleration end when the inertia is large. Set parameter b2-03 to apply DC injection to the motor, before it starts to accel- erate.
Changing the DC Injection Brake Current Using an Analog Input If you set H3-09 (Analog Input Terminal A2 Function Selection) to 6 (DC injection brake current), you can change the DC injection brake current level using the analog input. At 10 V input (voltage) or 20 mA input (current), 100% of the Inverter rated current will be applied.

Acceleration and Deceleration Characteristics Acceleration and Deceleration Characteristics Setting Acceleration and Deceleration Times The acceleration time indicates the time to increase the output frequency from 0% to 100% of the maximum output frequency (E1-04). The deceleration time indicates the time to decrease the output frequency from 100% to 0% of (E1-04).
Page 198
Switching Acceleration and Deceleration Time Using Multi-Function Input Terminal Commands Four different acceleration times and deceleration times can be set. When the multi-function input terminals (H1- ) are set to 7 (acceleration/deceleration time selection 1) and 1A (acceleration/deceleration time selection 2), you can switch the acceleration/deceleration time even during operation by combining the ON/OFF status of the terminals.
Page 199
Acceleration and Deceleration Characteristics Adjusting Acceleration and Deceleration Time Using an Analog Input If you set H3-09 (Analog Input Terminal A2 Function Selection) to 5 (acceleration/deceleration time gain), you can adjust the acceleration/deceleration time using terminal A2's input voltage. The resulting acceleration time is as follows: Acceleration time = C1-01 set value x acceleration/deceleration time gain Acceleration/deceleration time gain (Acceleration/deceleration gain from 1 to 10 V)

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 L3-01 is set to 1 (enabled) and the Inverter output current reaches 85 % of the set value in L3-02, the accel- eration rate will begin to slow down.

Operation Avoiding Resonance (Jump Frequency Function) The jump frequency function allows the prohibition or “jumping” of certain frequencies within the Inverter’s output frequency range so that the machine can operate without oscillations caused by resonant frequencies of the machine. It can also be used for deadband control. During acceleration and deceleration the output frequency goes linear through the prohibited frequency ranges, i.e.

Digital Operator Functions Prohibiting Overwriting of Parameters If A1-01 is set to 0, all parameters except A1-01 and A1-04 are write protected, U1- , U2- will be displayed. If A1-01 is set to 1, only the parameters A1-01, A1-04 and A2- can be read or written, U1- , U2-...
Displaying User-set Parameters Only The A2 parameters (user-set parameters) and A1-01 (parameter access level) can be used to establish a param- eter set that contains only the most important parameters. Set the number of the parameter to which you want to refer in A2-01 to A2-32, and then set A1-01 to 1. Using the advanced programming mode you can read and modify A1-01 to A1-03 and the parameters set in A2-01 to A2-32 only.

Troubleshooting Due to parameter setting errors, faulty wiring, and so on, the Inverter and motor may not operate as expected when the system is started. If that occurs, use this section as a reference and perform the appro- priate countermeasures. If the contents of the fault are displayed, refer to page 7-2, Protective and Diagnostic Functions.
Troubleshooting If the Motor Does Not Operate Properly The following causes are possible: Ensure the Digital Operator is securely connected to the Inverter. The motor does not operate when the RUN key on the Digital Operator is pressed. The following causes are possible: The LOCAL/REMOTE mode is not selected properly.
The motor stops during acceleration or when a load is connected. The load may be too large. The motor’s responsiveness limit may be exceeded if it is accelerated too rapidly by the Inverter’s stall prevention function or automatic torque boost function. Increase the acceleration time (C1-01) or reduce the motor load.
Troubleshooting If the Motor Operates at Higher Speed than the Frequency Reference PID control is enabled. If the PID control is enabled (b5-01 = 1 to 4), the Inverter output frequency will change to regulate the process variable to the desired setpoint. The PID can command a speed up to Maximum Output Frequency (E1-04) even though the reference is much lower.
If the Motor Overheats The following causes are possible: The load is too large. If the motor load is too large and the torque exceeds the motor’s rated torque, the motor may overheat. Reduce the loads by either reducing the load or increasing the acceleration/deceleration times. Also consider increas- ing the motor size.
Troubleshooting If There is Mechanical Oscillation Use the following information when there is machanical vibration: The application is making unusual sounds. The following causes are possible: There may be resonance between the mechanical system's natural frequency and the carrier frequency. This is characterized by the motor running with no noise generation, but the machinery vibrates with a high- pitched whine.
If auto-tuning has not been performed, proper performance may not be achieved for Closed Loop Vector Con- trol. Perform auto-tuning or set the motor parameters through hand calculations. Alternatively, change the Control Mode Selection to V/f Control (A1-02 = 0 or 1). Oscillation and hunting occur with PID control.
Maintenance and Inspection Periodic Inspection Check the following items during periodic maintenance. The motor should not vibrate or make unusal noises. • There should be no abnormal heat generation from the Inverter or motor. • The ambient temperature should be within the Inverter’s specifications. •...
Maintenance and Inspection Periodic Maintenance of Parts In order to keep the Inverter operating normally over a long period of time, and to prevent down time due to an unexpected failure, it is necessary to perform periodic inspections and replace parts according to their service life.
Cooling Fan Replacement 200 V and 400 V Class Inverters of 18.5 kW or Less A cooling fan is attached to the bottom of the Inverter.

Inverter Application Precautions Selection Observe the following precautions when selecting an Inverter. Installing Reactors A large peak current will flow in the power input circuit when the Inverter is connected to a large-capacity power transformer (600 kVA or higher) or when switching a compensating capacitor. Excessive peak current can destroy the converter section.
Inverter Application Precautions Installation Observe the following precautions when installing an Inverter. Installation in Enclosures Install the Inverter in a clean location where it is not subjected to oil mist, dust, and other contaminants, 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 exceed 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 control sequences carefully. Magnetic Contactor Installation If a magnetic contactor is installed in the power supply line do not exceed one start per hour.
Motor Application Precautions Motor Application Precautions Using the Inverter for an Existing Standard Motor Observe the following precautions when using an Inverter for an existing standard motor. Low Speed Ranges If a standard cooled motor is used at low speed the cooling effects are diminished. If the motor is used in con- stant torque applications in low speed area the motor may overheat.
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 an appropriate Inverter according to the maximum current of the motor. Submersible Motor The rated input current of submersible motors is higher than that of standard motors.
