Read the safety precautions in the VF-S7 Instruction Manual before powering up your VF-S7 unit. The S7 series has a built-in serial communication port. Using this RS-485 Option Unit, the ASD and a peripheral device such as a computer or PLC can communicate with each other. Please read the entire manual carefully before attempting to control your VF-S7 via RS-485 serial connection. Besides this operation manual, the “Serial Communications Option Manual” is needed to develop software which communicates with the VF-S7.

Carefully read those warnings and cautions because they are very important not only for safe and correct operation but also for preventing the equipment and operators from getting damaged or injured. After reading the operation manual of the ASD carefully with understanding of every note for safety, read this operation manual for carrying out connection and operation of the equipment correctly. GENERAL PRECAUTIONS DANGER! ? Never disassemble, remodel or repair the product. Not following this instruction could cause electrocution, fire or injury. Repair should only be performed by authorized service centers. NEVER DISASSEMBLE PROHIBITED ! MANDATORY ? Never put or insert any objects (cable scraps, rods, wires, etc.) into the ASD and the Option Unit. Not following this instruction could cause electrocution or fire. ? Do not splash water or liquid onto the ASD or the Option Unit. Not following these instructions could cause electrocution or fire. ? Whenever making wiring connections or setting the switch, be sure to turn all power to all related units off. ? If the ASD or the Option unit produces smoke, odor or abnormal noises turn off the input power immediately. Using the ASD or the Option unit in such a condition could result in a fire. CAUTIONS ON TRANSPORTATION AND INSTALLATION DANGER! ? PROHIBITED ? ? ! ? Do not operate the unit, when loose, broken, bent or otherwise damaged parts are found. Not following this instruction could cause electrocution or fire. Repair should only be performed by authorized service centers. Never install the unit in a place exposed to flammables, as this could cause a fire. Never install the unit in a place where water or liquid is splashed onto it, as this could cause electrocution or fire. Use the unit under the environmental conditions specified in the instruction manual, otherwise malfunctions or troubles could result. MANDATORY CAUTION! ? Avoid installation locations that may be subjected to large shocks or vibrations, otherwise the unit could fall and cause injury. PROHIBITED 2 Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.ctiautomation.net - Email: [email protected] 3 CAUTION ON OPERATION DANGER! PROHIBITED ? Do not wipe the unit with wet cloth. Not following this instruction could cause electrocution. ? Do not pull the communication cable, otherwise malfunctions or troubles could result. CAUTION ON DISPOSING OF OPTION UNIT CAUTION! ! ? Dispose of the used unit as industrial waste. Not following this instruction could cause injury. MANDATORY Cautions on use CAUTIONS ? Avoid installation locations that may be subjected to rapid changes in ambient temperature or/and humidity. ? Route the transmission cable separate from the ASD input/output power wiring. To avoid the possibly of electric shock due to leakage currents, always ground ? the ASD unit’s E/GND terminal and the motor. To avoid misoperation, do not connect RS-485 Option Unit’s SHIELD terminal to either of above-mentioned grounds or any other ground. ? When disconnecting connection cable, make sure to hold its connector with care not to give unreasonable stress to the cable and the unit. Since connectors of optional cables have locking pawls for disconnection prevention at the ASD and the Option Unit, disconnect such a connector while pressing the pawl by finger for unlocking. ? Mount the Option Unit securely on the panel, otherwise it could fall and cause malfunction or breakdown. ? Connect an electromagnetic contactor or the like between the ASD and the power source to secure external control of emergency stop of operation. Do not assign the same ASD number to more than one ASD in the same ? system. The ASD’s EEPROM has a life of 10,000 write cycles. Do not write to the same ? EEPROM address more than 10,000 times. 3 Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.ctiautomation.net - Email: [email protected] 4 1. Overview By using RS-485 Option Unit, a network can be constructed that allows communication between a host computer and multiple ASD units. A maximum of 32 Option Units can be connected on the same network. And two ASDs can be connected to one Option Unit. A maximum of 64 ASDs can be connected on the same network. (If ASD has a CPU whose version is V104 or V103, a maximum of 32 ASDs can be connected on the same network.) 2.

Connection and start-up Connect the ASD with a host computer according to the procedure mentioned below. Procedure (1) Set the communication speed to SW on the RS-485 Option Unit. (2) Connect terminating resistor in both ends of units. The RS-485 Option Unit has internal terminating resistor. Set SW3 and SW4 to ON to connect these terminating resistors. (3) Install the RS-485 Option Unit on a metal panel. (4) Connect the cable to the removable terminal block. If the stick-lugs are not used, strip the insulation from the wire and insert the wire directly into the terminal. Be sure not to short any wires. Run the cable as shown in the figure. Use a common cable in the system. (5) Connect the shield of the twisted pair cable to the SHIELD terminal on each RS-485 Option Unit, and make the ground connection. Do not connect Host computer ground to a power ground or any other noise-producing ground connection. (6) Insert the removable terminal block back into the RS-485 Option Unit. (7) Connect the communication connectors (INVERTER1 and INVERTER2) of the RS-485 Option Unit to the communication connector (CN1) of the ASD with the optional cable. (8) Turn on the power of ASD.
