Page 2: Warnings
• The products and specifications described in this manual or the content and presentation of the manual may be changed without notice to improve the product and/or the manual. • When ordering a new copy of this manual, due to damage or loss, contact your Yaskawa representatives or the nearest Yaskawa sales office. - Page 3 Installation CAUTION • Always hold the case when carrying the Inverter. If the Inverter is held by the front cover, the main body of the Inverter may fall, possibly resulting in injury. • Attach the Inverter to a metal or other noncombustible material. Fire can result if the Inverter is attached to a combustible material.
- Page 4 CAUTION • Disconnect the load (machine, device) from the motor before performing rotational autotuning or pole tuning. The motor may turn, possibly resulting in injury or damage to equipment. Also, motor parameters cannot be correctly set with the motor attached to a load. •...

Page 5: Warnings
Maintenance and Inspection WARNING • Do not touch the Inverter terminals. Some of the terminals carry high voltages and are extremely dangerous. Doing so can result in electric shock. • Always have the protective cover in place when power is being supplied to the Inverter. When attaching the cover, always turn OFF power to the Inverter through the MCCB. - Page 6 Safety Precautions and Instructions 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. Removal of housing components, the digital operator or terminal covers runs the risk of serious injuries or damage in the event of incorrect installa- tion or operation.

Page 7: Emc Compatibility
EMC Compatibility Introduction This manual was compiled to help system manufacturers using Yaskawa frequency inverters to design and install electrical switch gear. It also describes the measures necessary to comply with the EMC Directive. The manual's installation and wiring instructions must therefore be followed. - Page 8 All electrical equipment produces radio and line-borne interference at various frequencies. The cables pass this on to the environment like an aerial. Connecting an item of electrical equipment (e.g. drive) to a supply without a line filter can therefore allow HF or LF interference to get into the mains.

Page 9: Installation
Use a screwdriver or other tools to check for tightness. If you find any irregularities in the above items, contact the agency from which you purchased the Inverter or your Yaskawa representative immediately. Checking the Installation Site Before installing the inverter check the following: Make sure that the ambient temperature is not exceeded •... - Page 10 Installation Orientation Install the Inverter vertically so as not to reduce the cooling effect. When installing the Inverter, always pro- vide the following installation space to allow normal heat dissipation. 50 mm 120 mm 30 mm min. 30 mm min. 120 mm min.

Page 20: Autotuning
Autotuning The motor data autotuning function sets the V/f pattern parameters (E1- ), motor data parameters (E2- , E5- ) and the encoder data (F1-01) automatically. The steps which have to be performed during the autotuning depend on the tuning mode selection. Autotuning Mode Selection The autotuning mode has to be selected according to selected control mode and the mechanical system (motor no load rotation possible or not). -
Page 21: Autotuning Alarms And Faults
General Precautions: 1. Use rotating autotuning whenever high precision is required or for a motor that is not connected to a load. 2. Use not rotating autotuning whenever the load cannot be disconnected from the motor (e.g. the ropes can’t be removed). -

Page 28: Acceleration / Deceleration / Jerk Settings
Acceleration / Deceleration / Jerk Settings The acceleration time indicates the time to increase the speed from 0% to 100% of the maximum speed set in E1-04. The deceleration time indicates the time to decrease the speed from 100% to 0% of E1-04. The standard acceleration/deceleration times are set in the parameters C1-01/02, the jerk settings (S-curve) are set in the C2- parameters as shown in... - Page 29 5. When the motor has stopped, apply a DOWN command. The inverter will accelerate the motor in the opposite direction to the nominal speed. Release the DOWN command a few seconds after the nominal speed has been reached. To abort the tuning set parameter n5-05 to “0”. 1.

Page 30: Troubleshooting
Troubleshooting Fault and Alarm Detection Faults and Alarms are functions that indicate unusual inverter / application conditions. An alarm does not necessarily switch of the inverter but a message is displayed on the keypad and an alarm output is generated at the multi-function outputs (H2-01 to H2-03) if programmed. An alarm automatically disappears if the alarm condition is not present anymore. - Page 31 Displayed as Display Meaning Corrective Actions Alarm Fault • Perform the complete tuning procedure FF_CAL Feed forward motor acceleration time active • Abort the tuning by setting n5-05 = 0.
