    2.INSTALLATION 2.1 Pre-Installation Instructions Make sure that the input power of the inverter is off. CAUTION With input power on, do not install or remove the option unit. Otherwise, the inverter and option unit may be damaged. 2.2 Installation Procedure (1) Securely insert the connector of the option unit far into the connector of the inverter.
  • Page 9 INSTALLATION Inverter (without cover) Option unit Accessory screw (2 pcs.) Slot 1 Inverter side connector Slot 2 Option fixing hook Option side Slot 3 connector The slots 1, 2, and 3 are provided with an option fixing hook. CAUTION 1. Only one type of option per inverter may be used. When two or more options are mounted, pri- ority is in order of slots 1, 2 and 3, the options having lower priority are inoperative.

    INSTALLATION 2.3 Wiring Route the wires so that they do not take up a lot of space in the control circuit terminal block of the option unit. During wiring, do not leave wire off-cuts in the inverter. They may cause a fault, failure or malfunction. Use the space on the left side of the control circuit terminal unit to route the wires.

    PARAMETERS 4.2 Parameter Setting (1) Input selection [Pr.304 "Selection of digital input type and analog compensation input enable / disable." ] You can select the digital input signal type and whether compensation for digital input by analog input is enabled or not. When the setting is "9999" (factory setting), the 12-bit digital input is invalid. Analog Compensation Input* Digital Input Compensation...
  • Page 17 PARAMETERS (2) Data read timing signal on-off selection (Pr.305) Pr.305 setting Description The set frequency data (set speed data) entered from the digital signal input terminals is always imported independently of whether the DY signal is on or off. Digital signal input directly changes output frequency.
