  • Page 33 Using Intelligent Input Terminals Terminals [1], [2], [3], [4], [5], [6] and [7] are identical, programmable inputs for general use. The input circuits can use the inverter’s internal (isolated) +24V field supply or an external power supply. This section describes input circuits operation and how to connect them properly to switches or transistor outputs on field devices.
  • Page 34 The two diagrams below input wiring circuits using the inverter’s internal +24V supply. Each diagram shows the connection for simple switches, or for a field device with transistor outputs. Note that in the lower diagram, it is necessary to connect terminal [L] only when using the field device with transistors.
  • Page 35 The two diagrams below show input wiring circuits using an external supply. If using the “Sinking Inputs, External Supply” in below wiring diagram, be sure to remove the jumper wire, and use a diode (*) with the external supply. This will prevent a power supply contention in case the jumper wire is accidentally placed in the incorrect position.
  • Page 36 CAUTION: When using with plural inverters connected, connect a diode between sink logic: P24 and PLC and between source logic: L and PLC. The power to the inverter control part can be supplied externally as shown below. Except driving motor, it is possible read and write the parameters by keypad and via communication even the drive itself is not powered.
  • Page 37 Forward Run/Stop and Reverse Run/Stop Commands: When you input the Run command via the terminal [FW], the inverter executes the Forward Run command (high) or Stop command (low).

  • Page 40 Unattended Start Protection If the Run command is already set when power is turned ON, the inverter starts running immediately after powerup. The Unattended Start Protection (USP) function prevents that automatic startup, so that the inverter will not run without outside intervention. When USP is active and you need to reset an alarm and resume running, either turn the Run command OFF, or perform a reset operation by the terminal [RS] input or the keypad Stop/reset key.

If the motor cable length exceeds 20m, use output choke to avoid unexpected problem due to the leakage current from the motor cable (such as malfunction of the thermal relay, vibration of the motor, etc..).
  • Page 100 7. Minimize the distance between an interference source and an interference sink (interference- threatened device), thereby decreasing the effect of the emitted interference on the interference sink.  You should use only interference-free devices and maintain a minimum distance of 0.25 m from the adjustable frequency inverter.

  • Page 102 Hitachi EMC Recommendations WARNING: This equipment should be installed, adjusted, and serviced by qualified personal familiar with construction and operation of the equipment and the hazards involved. Failure to observe this precaution could result in bodily injury. Use the following checklist to ensure the inverter is within proper operating ranges and conditions.
  • Page 103 Functional Safety (EN ISO13849-1) Introduction The Gate Suppress function can be utilized to perform a safe stop according to the EN60204-1, stop category 0 (Uncontrolled stop by power removal) (as STO function of IEC/EN61800-5-2). It is designed to meet the requirements of the ISO13849-1, Cat.3 PL=d, IEC61508 SIL2 and IEC/EN61800-5-2 SIL2 only in a system in which EDM signal is monitored by an “external device monitor”.
  • Page 104 please turn the EDM function switch on. EDM output is automatically assigned on intelligent output terminal 11. (When safety switch or EDM switch is turned off, the intelligent input and output terminal assigned on will be set as "no" function, and contact will remain normally off.) Always use both inputs to disable the drive.

  • Page 106 inverter doesn’t block the current As described on page 4-14 of the Instruction manual, flowing into itself when it is not powered. This may cause the closed circuit when two or more inverters are connected to common I/O wiring as shown below to result in unexpected turning the on the input.
