[. . . ] The Y axis tries to recover a position within the software limits with the risk of exceeding the limits of the worm gear mechanism. As a precaution, make sure that the ram is in the upper area (I13 = 1) to make the home search sequence possible. If the machine has home switches (PAR14. 1 = 0), the contact point of the microswitch with the cam should not be too close to the position of the first reference mark (I0) of the encoder. The + limit switch is also the reference input that is deactivated when reversing the movement direction. A certain margin should be kept in order to reach a stable slow feedrate before receiving the reference mark (I0) also overshooting the amount of backlash set at PAR16. Standard clamps allow some rotation of the encoder body to make this adjustment easily. Once the home search is finished, the axis moves towards X- until it reaches the software travel limit (always less than the hardware limit set by the X+ home switch) until reaching the position = PAR13 - PAR26. On open-loop controls, the I0 signal sends a stop command; but there is no assurance that the axis will be held at that position. There is a slight overshooting even when selecting a slow home search speed. Selecting the reference value for PAR10 takes three steps: 1- Set PAR10 with any value and execute a home search for a first rough approach. Calculate the "" difference: = PAR10 - final position reached (+ value) 2- The final value for PAR10 will be: The requested distance between the support bases between the punch and the die + . to 8 . FSO1100X - Installation Manual - Page: 33 3. 1 PARAMETER SETTING Machine parameters PAR50, PAR51 and PAR90 enable special features of this NC. In initial mode, press [parameter number] . The rest can only be accessed by installers and technicians. for at least 2 seconds, when the displays start blinking, Key in the access code: 060496 to access the general parameters. Once on the menu, to access a particular parameter, press: [Parameter number] The LCD display will shows the parameter number and a short description. If it is a general parameter, its value is only shown on the first display. If it is an axis parameter, each axis display will show its current value. - To go to the next parameter saving the changes: Press or to go to the next one. or ) and key in its To return to the previous one, press - Pressing the key of the other axis ( - Pressing or ) saves the value of the previous axis and it goes on to edit the new selected axis. is pressed, the unit will ignore - If while changing the value of a parameter, the new value and will assume the previous one. Page: 34 - Installation Manual - FSO1100X Binary values (1/0) are displayed in an 8-digit row identified as 1 through 8 from right to left. X 8 PARAMETER FUNCTION PAR00 Feedback configuration, different per axis. This parameter sets the specific characteristics of the feedback device (rotary or linear encoder) used to read the axis position. Digit 8 Direction of the distance-coded Io (0 = Increasing, 1 = Decreasing) Fagor offers two types of linear encoders depending on the type of reference marks they use (Io): the standard one with several reference marks every 50 mm and the one with distance-coded reference marks (models with "O", e. g. : MOVX, FOP, etc. ). [. . . ] The minimum analog voltage PAR44, PAR45 is adjusted to reach the threshold voltage of proportional valves. Parameters PAR40 through PAR49 with very high ranges make it possible to distinguish the up and down response and compensate for any lack of linearity of the hydraulic circuits that activated the drain valves in the slow range of the bending stage. Figure 2 corresponds to an ideal adjustment of the bending stage that requires special attention in the following parameters: PAR45 PAR41-PAR19 PAR27 Minimum analog voltage. Adjustment of the dampening degree when switching from slow to minimum speed. [. . . ]
