[. . . ] Please gain a good understanding of the following pictorial symbols before reading this manual and strictly observe the instructions that follow each symbols. Marking Symbols Meaning Means that improper use or handling could cause the risk of death or serious Means that improper use or handling could cause injury to persons(*1) or Danger injury Warning damage to property(*2). (*1)"injury to persons" refer to injuries, burns, electric shocks, and so on, that do not oblige the injured person to be hospitalized or go to a hospital for a long period of time for medical treatment. (*2)"damage to property" includes all kinds of losses resulting from it. Symbols Meaning Represents prohibition(what you must not do) What you must not do is described in or near this symbol by a picture or words Represents mandatory items(what you must do) What you must do is described in or near this symbol by a picture or word Represents danger What is dangerous is described in or near this symbol by a picture or word Represents warning What the warning should be applied is described in or near this symbol by a picture or word Limited applications This inverter is designed to control the speed of three-phase induction motors for general industry. Precautions When using our inverters for equipment such as nuclear power control equipment, aviation and space flight control equipment, traffic equipment, and safety equipment, and there is a risk that any failure or malfunction of the inverter could directly endanger human life or cause injury, please contact our headquarters, branch, or office printed on the front and back covers of this catalogue. Such applications must be studied carefully. When using inverters for critical equipment, even though the inverters are manufactured under strict quality control always fit your equipment with safety devices to prevent serious accident or loss should the inverter fail(such as failure to issue an inverter trouble signal) Do not use our inverters for any load other than three phase induction motors. 1 Handling in general Danger Never Disassemble Never disassemble, modify or repair the inverter. Its disassembly could cause an electric shock, afire or an injury.

When using an external braking resistor instead of the internal resistor, change the connection of the internal resistor from terminal PB1 to terminal PR1. (For boosting braking force) Do not connect an external resistor with a resistance (combined resistance) smaller than the minimum admissible resistance. For overload protection, be sure to set the parameters and properly.

[ ] Any value (*3) [kW] Any value (*3) (When the standard internal braking resistor option is not used, be sure to set the parameters F308 and F309 properly for overload protection. ) (*3) is for overload protection of our optional PBR and PBR3 type. Please consider the protection at external thermal for DGP type. A thermal relay (THR) must be connected as the last resort for fire prevention in case a failure occurs in the overload and over-current protective functions provided for the inverter to protect the braking resistor. Select and connect a thermal relay (THR) with a capacity (watt) with that of the braking resistor used. commensurate [Parameter setting] Title Function Dynamic braking mode selection PBR resistor PBR resistor capacity Adjustment range : Disabled : Enabled with over load detection Setting value - Caution In the above circuit, the MC in the main circuit is turned off if an inverter's protective function is activated, and consequently no trip message is displayed. The inverter recovers from a trip if it is turned off. These parameters can adjust the frequency range, the insensitive torque band and gains. Drooping gain Internal torque reference Drooping gain Speed at a drooping gain 0% Speed at the drooping gain Drooping insensitive torque band Output filter for drooping Drooping gain Frequency Dead band Dead band [Parameter setting] Title Function Adjustment range [%] [Hz] [Hz] [%] [rad/s] Default setting Drooping gain Speed at a drooping gain 0[%] Speed at the drooping gain Drooping insensitive torque band Output filter for drooping When torque larger than the dead band torque is applied, the frequency is decreased (during power running) or increased (during regenerative braking). Drooping takes effect within the frequency range above the frequency set with . In the frequency range between and , the drooping rate varies with the torque. The change in the frequency during drooping can be calculated as described below. a) Gain by internal torque reference (Gain 1) If internal torque reference [%] 0 Gain1 internal torque reference dead band Grain 1 needs to be set at 0 or a positive number. If internal torque reference [%] 0 Gain1 internal torque reference dead band Grain 1 needs to be set at 0 or a negative number. b) Gain by frequency after acceleration (Gain 2) If Frequency after acceleration Gain2 0 Frequency 2 set with / 100 Frequency 1 set with / 100 / 100 Frequency after acceleration Gain2 Drooping gain F-31 If frequency 1 Gain2 frequency after acceleration ( freq. 2 frequency 2 freq. 1 ) Drooping gain 100 ( freq. after acceleration freq. 1 ) If If frequency after acceleration Gain2 0 frequency 1 If frequency after acceleration Gain2 Drooping gain frequency 1 / 100 c) Drooping speed Drooping speed = base frequency Note Gain1 Gain2 Note) For this calculation, assume the base frequency to be 100 Hz if it is higher than 100 [Hz]. 6. 15 Function for crane/hoist Light-load high-speed operation Light-load high-speed operation switching lower limit frequency Light-load high-speed operation load waiting time Light-load high-speed operation load detection time Light-load high-speed operation heavy load detection time Switching load torque current during forward run Heavy load torque during acceleration in forward direction Heavy load torque during fixed speed in forward direction Switching load torque current during reverse run Heavy load torque during acceleration in reverse direction Heavy load torque during fixed speed in reverse direction Automatic light-load high-speed operation frequency 6. 16 Commercial power/inverter switching Output signal selection of commercial power/inverter switching Commercial power/inverter switching frequency Inverter side switching waiting time Commercial power side switching waiting time Commercial power switching frequency holding time Function The function switches between the commercial power and the inverter operation witho ut stopping the motor in case of tripping or by sending a signal, and also to transmit switching signals to an external sequence (MC, etc).
