Upper and Lower Frequency Reference Limi. Setting Frequency References through Key. Setting Frequency References by Pulse Tr. Precise Vector Control Settings and Adju. Adjusting Output Torque in Vector Contro. Communications with Programmable Control. Motor Rotates after Output of Inverter i. Proper use and handling of the product will ensure proper product performance, will lengthen product life, and may prevent possible accidents. Maximum Applicable Motor Capacity 0. W Note The figures in parentheses indicate capacities for motors used outside Japan. Front Cover options Blank cover No potentiometer. Doing so while the RUN signal is turned ON may result in injury. Caution Be sure to confirm permissible ranges of motors and machines before operation because the Inverter speed can be easily changed from low to high. Caution If you use a Braking Resistor or a Braking Resistor Unit, connect them as specified in the manual. Table of Contents Setting the Frequency Reference . Selecting the Frequency Reference. Load Drops when Brakes are Applied . Controller or AM Radio Receives Noise when Inverter is Started. Note The figures in parentheses indicate capacities for motors used outside Japan. Protocol, thus making it possible to easily construct networks with the use of the Protocol Macro or ASCII Unit mounted on an OMRON SYSMAC PC. BUS Communications Protocol is a trademark of AEG Schneider Automation. FREQUENCY Sets the frequency reference within a range adjuster between 0 Hz and the maximum output frequency. Overview Chapter 1 Appearance Name Function PRGM indicator The parameters in n001 through n179 can be set or monitored while this indicator is lit. Note While the Inverter is in operation, the parameters can be only monitored and only some parameters can be changed. Any RUN command input is ignored while this indicator is lit. Installation Conditions WARNING Provide an appropriate stopping device on the machine side to secure safety. Design Chapter 2 H Removing the Terminal Cover 0. Digital Operator in the arrow 1 direction as shown in the following illustration. Wiring WARNING Wiring must be performed only after confirming that the power supply has been turned OFF. There is a label under the front cover indicating the arrangement of main circuit terminals. The functions in parentheses are the default settings. NPN is the default setting for these terminals. Wire them by providing a common Note 2. By using SW1, NPN or PNP input can be selected as shown below. Set to ON only if the Unit is the end Slave. By using pin 2 of SW2, voltage input or current input can be selected as the input method for frequency reference. Install one wiring circuit breaker per Inverter. Inverters, choose a ground fault interrupter with a sensitivity amperage of at least 10 mA per Inverter. A or more per Inverter and with an operating time of 0. Noise Filter for the SYSDRIVE 3G3MV. T3 to motor lead wires U, V, and W. RC Noise Filter to the output circuit. Doing so will result in damage to the Inverter or cause other parts to burn. D Do not Use an Electromagnetic Switch of Magnetic Contactor Do not connect an electromagnetic switch of magnetic contactor to the output circuit. Design Chapter 2 D Countermeasures against Induction Noise As described previously, a Noise Filter can be used to prevent induction noise from being generated on the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent induction noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces induction noise. Design Chapter 2 Cable length 50 m max. More than 100 m Carrier frequency 10 kHz max. V Inverter with a ground resistance of 100 W or less. V Inverter with a ground resistance of 10 W or less. Do not share the ground wire with other devices such as welding machines or power tools. Design Chapter 2 Reactor Effects Harmonics are effectively suppressed when the DC reactor is used with the AC reactor as shown in the following table. Wiring Control Circuit Terminals A control signal line must be 50 m maximum and separated from power lines. O terminal under the following conditions. Design Chapter 2 D Solderless Terminals for Control Circuit Terminals The use of solderless terminals for the control circuit terminals is recommended because solderless terminals are easy to connect securely. Note When using the following solderless terminal, make sure that the wire size is 0. Conforming to EC Directive The following description provides the wiring method of the Inverter to meet EC Directive requirements. If the following requirements are not satisfied, the whole equipment incorporating the Inverter will need further confirmation. H Standard Connection D Main Circuit Terminals Braking Resistor. Design Chapter 2 H Conforming to EC Directives D Wiring the Power Supply Make sure that the Inverter and Noise Filter are grounded together. Reduce the length of the ground wire as much as possible. When connect filexlib.
