N500 INSTRUCTION MANUAL OperationChapter 1 Operation• Be sure not to touch the main terminal or to check the signal or put on/off wire and/or connector. Otherwise, there is a danger of electric shock. • Be sure to turn on the input power supply after closing from cover. While being energized, be sure not to open the front cover. Otherwise, there is a danger of electric shock. • Be sure not to operate the switches with wet hands. Otherwise, there is a danger of electric shock. • While the inverter is energized, be sure not to touch the inverter terminals even during stoppage. Otherwise, there is a danger of electric shock. • If the retry mode is selected, it may suddenly restart during the trip stop. Be sure not to approach the machine.(Be sure to design the machger of ine so that personnel safety will be secured even if it restarts.) Otherwise, there is a daninjury. • Be sure not to select retry mode for up and down equipment or traveling equipment, because there is output free-running mode in term of retry. Otherwise, there is a danger of injury and/or machine breakage • Even if the power supply is cut for a short period of time, it may restart operation after the power supply is recovered if the operation command is given. If it may incur danger to personnel, be sure to make acircuit so that it will not restart after power recovery. Otherwise, there is a danger of injury. • The stop key is effective only when the function is set. emergency stop. Otherwise, there is a danger of injury. • After the operation command is given, if the alarm reset is conducted, it will restart suddenly. Be sure to set the alarm reset after checking the operation command is off. Otherwise, there is a danger of injury. • Be sure not to touch the inside of the energized inverter or to put a bar into it. Otherwise, there is a danger of electric shock and/or fire. Be sure to prepare the key separately from the1 1-1 N500 INSTRUCTION MANUAL Operation• Cooling fin will have high temperature. Be sure not to touch them. Otherwise, there is a danger of getting burned. • Low to high speed operation of the inverter can be easily set. Be sure to operate it after checking the tolerance of the motor and machine. Otherwise, there is a danger of injury. • Install external break system if needed. Otherwise, there is a danger of injury. • If a motor is operated at a frequency higher than standard setting value(50Hz / 60Hz), be sure to check the speeds of the motor and the machine with each manufacturer, and after getting their consent, operate them. Otherwise, there is a danger of machine breakage. • Check the following before and during the test run. Otherwise, there is a danger of machine breakage. Was the direction of motor correct? Was the inverter tripped during acceleration or deceleration? Were the rpm and frequency meter correct? Were there any abnormal motor vibrations or noise?2 1-2N500 INSTRUCTION MANUALOperation1.1 OperationThis inverter requires two different signals in order for the Inverter to operate correctly. The Inverter requires both an operation setting and a frequency setting. The following indicates the details of each method of operation and the necessary instructions for operation.(1) Operation setting and a frequency setting by the terminal control. This is the method by connecting signals from the outside (the frequency setting, the starting switch etc.) with the control circuit terminals. The operation is started when the operation setting (FWD, REV) is turned ON while the input power is turned ON. NOTE: The methods of the setting frequency with terminal are the voltage setting and the electric setting. And they are selective by each system. The control circuit terminal list shows this in detail. (Necessary things for operation) [1] The operation setting: switch, relay etc. [2] The frequency setting: signals from volume or outside (DCO-10V, DC-10-10V, 4-20mA etc.) (2) Operation setting and frequency setting with the digital operator. This is the method for operation from the digital operator, which comes equipped with the inverter as standard, or the remote operator keypad. When the digital operator sets the operation, the terminals (FWD, REV) don’t need to be linked. And it is possible to select frequency from the digital operator as a method of the frequency setting too. (Necessary things for operation) [1]
