Page 52: Wiring The Main Circuits
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 53 Wiring Main Circuit Terminals 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.
Page 54 Incorrect Noise Filter Installation • Power supply MCCB Inverter MCCB General- Other purpose controllers noise filter Power MCCB supply General- Inverter purpose noise filter MCCB Other controllers Do not use general-purpose noise filters. No general- purpose noise filter can effectively suppress noise generated from the Inverter.
Page 55 Wiring Main Circuit Terminals operation. If measures for momentary power interrupts are required, use a delayed release the magnetic con- tactor. Installing a Thermal Overload Relay This Inverter has an electronic thermal protection function to protect the motor from overheating. If, however, more than one motor is operated with one Inverter or a multi-polar motor is used, always install a thermal relay (THR) between the Inverter and the motor and set L1-01 to 0 (no motor protection).
Page 56: Ground Wiring
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.

Page 103 Precautions for Rotational and Stationary Autotuning Lower the base voltage based on Fig 4.4 to prevent saturation of the Inverter’s output voltage when the rated voltage of the motor is higher than the voltage of the power supply to the Inverter. Use the following proce- dure to perform autotuning.
Page 104 Trial Operation Procedures If the values of E2-02 and E2-03 differed greatly from the reference data of the motor in the test report or the instruction manual, hunting, motor vibrations, insufficient motor torque, or an overcurrent may occur because the motor is operated although the aforementioned conditions have not been fulfilled after stationary autotun- ing 1.

Temporarily Switching Operation between Digital Operator and Control Circuit Terminals You can switch the Inverter Run Command inputs and frequency reference inputs between local (i.e., Digital Operator) and remote (input method using b1-01 and b1-02).
Page 283: Blocking Inverter Outputs (Baseblock Commands)
Input Terminal Functions Blocking Inverter Outputs (Baseblock Commands) Set 8 or 9 (Baseblock command NO/NC) in one of the constants H1-01 to H1-10 (multi-function contact input terminal S3 to S12 function selection) to perform baseblock commands using the terminal's ON/OFF opera- tion, and prohibit Inverter output using the baseblock commands.
Page 284: Stopping Acceleration And Deceleration (Acceleration/Deceleration Ramp Hold)
Stopping Acceleration and Deceleration (Acceleration/Deceleration Ramp Hold) The acceleration/deceleration ramp hold function stops acceleration and deceleration, stores the output fre- quency at that point in time, and then continues operation. Set one of the constants H1-01 to H1-10 (multi-function contact input terminal S3 to S12 function selection) to A (acceleration/deceleration ramp hold) to stop acceleration and deceleration when the terminal is turned ON and to store the output frequency at that point in time.
Page 285: Raising And Lowering Frequency References Using Contact Signals (Up/Down)
Input Terminal Functions Application Precautions When d4-01 is set to 1, the output frequency on hold is stored even after the power supply is turned OFF. If • performing operations using this frequency after the Inverter has also been turned OFF, input the Run Command with the Acceleration/Deceleration Ramp Hold turned ON.
Page 286 Application Precautions Frequency outputs using UP/DOWN commands are limited by the frequency reference upper and lower • limits set in constants d2-01 to d2-03. Here, frequency references from analog frequency reference termi- nal A1 becomes the frequency reference lower limit. If using a combination of the frequency reference from terminal A1 and the frequency reference lower limit set in either constant d2-02 or d2-03, the larger lower limit will become the frequency reference lower limit.

Accelerating and Decelerating Constant Frequencies in the Analog Refer- ences (+/- Speed) The +/- speed function increments or decrements the frequency set in analog frequency reference d4-02 (+/- Speed Limit) using two contact signal inputs. To use this function, set One of the constants H1-01 to H1-10 (multi-function contact terminal inputs S3 to S12 function selection) to 1C (Trim Control Increase command) and 1D (Trim Control Decrease command).

Suppressing Overshoot If overshoot occurs, reduce derivative time (D), and increase integral time (I). Response Before adjustment After adjustment Time Set a Rapidly Stabilizing Control Condition To rapidly stabilize the control even if overshoot occurs, reduce integral time (I), and lengthen derivative time (D).
Page 318 Suppressing Short Cycle Vibration If vibration occurs when the vibration cycle is short, and the cycle is almost identical to the derivative time (D) set value, the differential operation is too strong. Shorten the derivative time (D) to suppress the vibration. If vibration continues even when the derivative time (D) is set to 0.00 (D control disabled), reduce the propor- tional gain (P), or increase the PID primary delay time constant.

Page 339 Individual Functions Rewinding Operation In a rewinding operation, the line (speed) and torque generated by the motor are in the opposite directions. (In this example, we’ll assume that the line speed is positive and the torque reference input is negative.) For the rewinding operation, the speed limit is positive and the torque reference input is negative.
Page 340 Setting the Torque Compensation Set multi-function analog input A2 or A3 to torque compensation (setting 14). When the amount of torque loss for mechanical loss or other factor at the load is input to one of these terminals, it is added to the torque refer- ence to compensate for the loss.
Page 341 Individual Functions Setting the Speed/Torque Control Switching Timer The delay between a change in the speed/control switching function input (ON to OFF or OFF to ON) and the corresponding change in the control method can be set in d5-06. During the timer delay, the value of the 3 ana- log inputs will retain the values they had when the ON/OFF status of speed/torque control switching signal was changed.

Page 344: Fine Adjustments
Speed Control (ASR) Gain Adjustment for Vector Control Use the following procedure to adjust C5-01 and C5-03 with the mechanical system and actual load con- nected. At zero-speed, increase C5-01 (ASR P Gain 1) until there is no oscillation. At zero-speed, decrease C5-02 (ASR I Time 1) until there is no oscillation.
Page 345 Individual Functions Adjusting ASR Proportional Gain 1 (C5-01) This gain setting adjusts the responsiveness of the speed control (ASR). The responsiveness is increased when this setting is increased. Usually this setting is higher for larger loads. Oscillation will occur if this setting is increased too much.
Page 346 Different Gain Settings for Low-speed and High-speed Switch between low-speed and high-speed gain when oscillation occurs because of resonance with the mechanical system at low speed or high speed. The proportional gain P and integral time I can be switched according to the motor speed, as shown below.
Page 347 Individual Functions Precautions for Open-loop Vector 2 Control (PRG: 102 only) The ASR primary delay time setting for open-loop vector 2 control is divided between constants C5-06 • and C5-10. The constant that is used depends on the size of the operating frequency. If the operating fre- quency is between 0 and 35 Hz, adjust the setting using C5-06, and if the operating frequency is greater than 35 Hz, adjust the setting using C5-10.
Page 348: Increasing The Speed Reference Response (Feed Forward Control)
Increasing the Speed Reference Response (Feed Forward Control) Use feed forward control to increase the responsiveness to speed references. This function is effective for machines for which the ASR gain cannot be increased to a large value because doing so would result in vibra- tions.

Troubleshooting 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.
Page 416: If The Motor Does Not Operate
If the Motor Does Not Operate Use the following information if the motor does not operate. The motor does not operate when the RUN Key on the Digital Operator is pressed. The following causes are possible. If the Inverter is not in drive mode and the DRIVE indicator on the Digital Operator (JVOP-161) does not light up, the Inverter will remain in ready status and will not start.
Page 417 Troubleshooting The operation method selection is wrong. If constant b1-02 (reference selection) is set to 0 (Digital Operator), the motor will not operate when an exter- nal 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.

Page 419: If The Direction Of The Motor Rotation Is Reversed
Troubleshooting The motor only rotates in one direction. “Reverse run prohibited” is selected. If b1-04 (Prohibition of Reverse Operation) is set to 1 (reverse run pro- hibited), the Inverter will not receive Reverse Run Commands. To use both forward and reverse operation, set b1-04 to 0.
Page 420: If The Slip Compensation Function Has Low Speed Precision
The analog frequency reference bias setting is wrong (the gain setting is wrong). The frequency reference bias set in constant H3-03 is added to the frequency reference. Check to be sure that the set value is suitable. A signal is being input to the frequency reference (current) terminal A2 or A3. When 0 (Add to terminal A1) is set for constant H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-function Analog Input Terminal A3 Function Selection), a frequency correspond- ing to the terminal A2 or A3 input voltage (current) is added to the frequency reference.

Page 462: Inverter Application Precautions
Inverter Application Precautions This section provides precautions for selecting, installing, setting, and handling Inverters. Selection Observe the following precautions in 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 phase advancing capacitor.
Page 463: 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 464: Handling
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 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.
Page 465: 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 466: Using The Inverter For Special Motors
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.
