  • x CAUTION: Do not stop operation by switching OFF electromagnetic contactors on the primary or secondary sides of the inverter. When there has been a sudden power failure while an operation instruction is active, then the unit may restart operation automatically after the power failure has ended. If there is a possibility that such an occurrence may harm humans, then install an electro

  • Hitachi SJ2002 Series, SJ2002 Inverter Configuring Drive Parameters 3–37 Software Lock Mode The software lock function keeps personnel from accidentally changing parameters in the inverter memory. Use B031 to select from various protection levels. The table below lists all combinations of B031 option codes and the ON/OFF state of the [SFT] input. Each Check ✔ or Ex ✘ indicates whether the corresponding parameter(s) can be edited. The Standard Parameters column below lists Low and High level access for some lock modes. These refer to the parameter tables throughout this chapter, each of which

  • Hitachi SJ2002 Series, SJ2002 Inverter Getting Started 1–3 Operator Interface Options The SJ2002 inverter has a removable keypad, as shown to the right (part no. OPE–SRmini). This allows the keypad to operate the inverter remotely, as shown (below, left). A cable (part no. ICS–1 or ICS–3, 1m or 3m) connects the modular connectors of the keypad and inverter. Hitachi provides a panel mount keypad kit (below, right). It includes the mounting flange, gasket, keypad, and other hardware. You can mount the keypad with the potentiometer for a NEMA1 rated installation. The kit also provides for removing the potentiometer knob to meet NEMA 4X requirements, a

  • Hitachi SJ2002 Series, Using Intelligent Output Terminals Operations and Monitoring 4–44 Alarm Signal The inverter alarm signal is active when a fault has occurred and it is in the Trip Mode (refer to the diagram at right). When the fault is cleared the alarm signal becomes inactive. We must make a distinction between the alarm signal AL and the alarm relay contacts [AL0], [AL1] and [AL2]. The signal AL is a logic function, which you can assign to the open collec- tor output terminals [11] or [12] or the relay outputs. The most common (and default) use of the relay is for AL, thus the labeling of its terminals. Use an open collector output (terminal [11

  • Hitachi SJ2002 Series, SJ2002 Inverter Appendix B B–17 Exception Response: When sending a query (excluding a broadcasting query) to an inverter, the master always requests a response from the inverter. Usually, the inverter returns a response according to the query. However, when finding an error in the query, the inverter returns an excep- tion response. The exception response consists of the fields shown below. The content of each field is explained below. The function code of the exception response is the sum of the function code of the query and 80h. The exception code indicates the factor of the exception response.

  • Hitachi SJ2002 Series, SJ2002 Inverter Operations and Monitoring 4–59 Configuring the Inverter for Multiple Motors Simultaneous Connections For some applications, you may need to connect two or more motors (wired in parallel) to a single inverter’s output. For example, this is common in conveyor applications where two separate conveyors need to have approximately the same speed. The use of two motors may be less expensive than making the mechanical link for one motor to drive multiple conveyors. Some of the characteristics of using multiple motors with one drive are: • Use
