Page 73 Setting User Constants 4.2.3 User Constant Access Levels 4.2.3 User Constant Access Levels The VS-616G5 has three access levels which divide the various user constants based on their applications, as shown below. The access level restricts which user constants can be set or displayed. Quick-start Allows reading/setting of user constants required for simple operation.
Page 74 4.2 Modes Setting User Constants in Each Access Level The displayed access level will change when programming mode is selected. The display will not change for access levels in operation mode, initialize mode, autotuning mode, and modified constants mode.

Page 158 Advanced Operation 7.1.1 Torque Limit Function 7.1.1 Torque Limit Function With open-loop vector control, torque limits can be applied at an arbitrary value because the torque output by the motor is calculated internally. The torque limit function is useful when the load cannot sustain a torque above a certain level or to maintain the regenerative torque above a certain level.
Page 159 7.1 Open-loop Vector Control Settings Setting Name Forward Torque Limit Reverse Torque Limit Regenerative Torque Limit Forward/Reverse Torque Limit The above table shows only those settings related to the torque limit function. Set the analog input terminal’s signal level, gain, and bias to match the actual input signal. The factory settings for the input terminal’s signal level are as follows: Terminal 16: 0 to 10 V (A 10 V input limits the torque to 100% of the motor’s rated torque.)

Page 162 Advanced Operation 7.1.4 Operation Selection when Output Voltage Saturated The default setting depends upon the Inverter capacity. (The table shows the default settings for 200 V class, 0.4 kW Inverters.) Set the motor terminal resistance (U−V, V−W, and W−U) in constant E2-05. Normally this value isn’t shown on the motor nameplate, so it might be necessary to contact the motor manufacturer for the ter- minal resistance at the insulation class temperature.
Page 163 7.1 Open-loop Vector Control If the limited output voltage operation is disabled and output voltage becomes saturated, slip com- pensation is automatically disabled to prevent instability. The output current does not change when the slip compensation is disabled, however precise speed control is no longer possible.
Page 164 Advanced Operation 7.1.5 Starting Torque Compensation Function (for SPEC:F) Set the constant for starting torque compensation (C4-05) to a large value if a shock is generated during startup. Alternatively, use DC injection braking (b2-03) at startup or the DC braking command for multifunc- tion contact input (setting: 60), and start motor magnetic flux before startup.

Page 306 Troubleshooting 9.1.1 Fault Detection 9.1 Protective and Diagnostic Functions 9.1.1 Fault Detection When the Inverter detects a fault, the fault code is displayed on the Digital Operator, the fault contact output operates, and the Inverter output is shut OFF causing the motor to coast to a stop. (The stopping method can be selected for some faults, and the selected stopping method will be used with these faults.) When a fault has occurred, refer to the following table to identify and correct the cause of the fault.

Page 313 9.2 Troubleshooting 9.2 Troubleshooting Due to constant setting errors, faulty wiring, and so on, the Inverter and motor may not operate as expected when the system is started up. If that should occur, use this section as a reference and apply the appropriate measures. If the contents of the fault are displayed, refer to 9.1 Protective and Diagnostic Functions.

Page 315 9.2 Troubleshooting 9.2.3 If the Direction of the Motor Rotation is Reversed The motor output wiring is faulty. When the Inverter T1(U), T2(V), and T3(W) are properly connected to the motor T1(U), T2(V), and T3(W), the motor operates in a forward direction when a forward run command is executed.

Page 331 12.1 Inverter Application Precautions 12.1.3 Settings Upper Limits The Digital Operator can be used to set high-speed operation up to a maximum of 400 Hz. Incorrect settings can be dangerous. Use the maximum frequency setting functions to set upper limits. (The maximum output frequency is factory-set to 60 Hz.) DC Injection Braking The motor can overheat if the DC injection braking voltage or braking time is set to a large value.
Page 332 Frequency (Hz) 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 Yaskawa representative for details. High-speed Operation When using the motor at a high speed (60 Hz or more), problems may arise in dynamic balance and bearing durability.
Page 333 12.2 Motor Application Precautions 12.2.2 Using the Inverter for Special Motors 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.
Page 334 Select the MCCBaccording to the Inverter’spower supplypower factor (which changes with the supplyvolt- age, output frequency, and load) . Contact your Yaskawa representative for selection standards. Operating characteristics of completely magnetic MCCBs change with high-frequency currents. Select a model with a large capacity.
Page 335 12.3 Peripheral Device Application Precautions Wire Sizes and Distances Motor torque will be reduced by voltage drop along the cable if the distance between the Inverter and the motor is too long. This is particularly noticeable for low-frequency outputs. Use wires of sufficient size. Always use the optional extension cables when operating the Digital Operator separated from the Inverter.
