    3. Setup WARNING Always turn on the power to the power amplifier before turning on the power to hydraulic equipment and machinery. Failure to turn the power on in this sequence may cause the equipment to misoperate. 3.1 Functions of Each Button 1) ITEM change key (Switches between monitor, data set, and control parameter set modes) Used to change the display mode and select the setting item.

  • Page 12: Mode Settings

    3.2 Mode Settings Pressing the ITEM key for 3 seconds or more in monitor mode changes to control parameter setting mode. Use the ITEM + [ ] and [ ] keys to select the item and use the [ ] and [ ] keys to change the contents of the selected item.
  • Page 13 6) Slope waveform selection If you wish to avoid any shock to the device on which you are performing hydraulic control, selecting an S shaped curve for the slope waveform smoothes any shock when movement starts or stops. Setting: 0 to 9 (10 types) (Preset in factory: Type 0) Slope waveform types The figures in brackets ( ) indicate the points at which the waveform curves.
  • Page 14 7) Current limit setting Sets the current limit value. Setting range: 0.0 to 2.0 [A] (Preset in factory: 1.1 [A]) Set 1.1 [A] if driving the EDFG valve. (See section 4.2) 8) Dither frequency setting Sets the dither frequency. Setting range: 0 to 9 (100 to 190 [Hz]) (Preset in factory: 2 (120 [Hz])) Dither frequency = (Dither setting) ×...
  • Page 15 12) Control mode selection Selects the control mode. P.0 : Shockless control mode (Preset in factory) P.1 : G valve control mode 1) Shockless control mode: This mode outputs a L→H→L shockless pattern. Output Input Signal 2) G valve control mode: This control mode is equivalent to that for shifting time adjustable type shockless valve.

    3.3 Output Data Settings 1) Data setting procedure Press the ITEM key twice in succession to select data set mode. (The mode changes alternately at each key press) ITEM Use the ITEM + [ ] and [ ] keys to select the item or point to set. ▲...
  • Page 17 3) Slope time setting The following describes the procedure for setting the slope time in switching the current output to the next output. When slope constant selected: SLOPE = [MAX slope time]×[SLOPE setting]×([Target LEVEL] – [Current LEVEL]) When time constant selected: SLOPE = [MAX slope time]×[SLOPE setting] Slope setting display When setting the slope, the SLOPE and corresponding point indicating lamps turn on.
