Cables must not be connected or disconnected, nor signal tests carried out, while the power is switched on. The Varispeed F7 DC bus capacitor remains charged even after the power has been switched off. To avoid an electric shock hazard, disconnect the frequency inverter from the mains before carrying out maintenance.
Page 9: Safety Precautions And Instructions For Use
Safety Precautions and Instructions for Use General Please read these safety precautions and instructions for use thoroughly before installing and operating this inverter. Also read all of the warning signs on the inverter and ensure they are never damaged or removed. Live and hot inverter components may be accessible during operation.
Page 10: Electrical Connection
In certain systems it may be necessary to use additional monitoring and safety devices in compliance with the relevant safety and accident prevention regulations. The frequency inverter hardware must not be modified. Notes The VARISPEED F7 frequency inverters are certified to CE, UL, and c-UL.

If T1-09 is not set the value of a Yaskawa standard motor will be used. Precautions Before Using Autotuning Read the following precautions before using autotuning.
Page 95 Precautions for Rotating and Non-rotating Autotuning If the motor rated voltage is higher than the power supply voltage, lower the base voltage value like shown • Fig 4.3 to prevent saturation of the Inverter’s output voltage. Use the following procedure to perform autotuning.

Page 188 Carrier Frequency and Inverter Overload Capability The inverter overload capability depends among other things on the carrier frequency setting. If the carrier fre- quency 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 189 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 capability is reduced like shown in Fig 6.3.

Page 311: Droop Control Function
Droop Control Function Droop control is a function that allows to achieve a load sharing between two motors that drive a single load. The Droop Control function must be enabled at one inverter only. If by this inverter the torque rises, the speed is reduced and the other inverter takes over more load.

Zero-Servo Function The Zero-Servo function holds the motor when the motor is stopped in a so called Zero-Servo status. This means, that if the frequency reference falls below the Zero-Speed level (parameter b2-01) a position loop is activated and the motor is kept at the position, even if a load is applied. The zero-servo function must be enabled using a digital input, which is programmed for is set to Zero-Servo command (H1- = 72).

Using parameter o2-07 the cumulative operation time can be changed, e.g. after a replacement of the control board. If parameter o2-08 is set to 0 the inverter counts the time whenever the power supply is switched ON. If o2-08 is set to 1 the time when a RUN command is active is counted only.

Page 356: If The Motor Does Not Operate Properly
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.
Page 357: If The Direction Of The Motor Rotation Is Reversed
The motor only rotates in one direction. "Reverse run disabled" may be selected. If b1-04 (Prohibition of Reverse Operation) is set to 1 (reverse run prohibited), the Inverter will not accept any reverse run commands. If the Direction of the Motor Rotation is Reversed If the motor rotates in the wrong direction, the motor output wiring may be incorrect.
Page 358: If The Motor Operates At Higher Speed Than The Frequency Reference
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 set point. The PID can command a speed up to Maximum Output Frequency (E1-04) even though the reference is much lower.
Page 359: If The Motor Overheats
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.
Page 360: If There Is Mechanical Oscillation
If There is Mechanical Oscillation Use the following information when there is mechanical 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.
Page 361: If The Motor Rotates Even When Inverter Output Is Stopped
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.

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.
Page 378: 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.
Page 379: Power Transmission Mechanism (Speed Reducers, Belts And Chains)
Synchronous Motor A synchronous motor is not suitable for Inverter control. Single-phase Motor Do not use an Inverter for a single-phase capacitor motor. Any capacitors directly connected to the inverter output may damage the Inverter. Power Transmission Mechanism (Speed Reducers, Belts and Chains) If an oil-lubricated gearbox or speed reducer is used in the power transmission mechanism, oil lubrication will be affected when the motor operates only in the low speed range.
