3、tant for encoder decoding circuit, the value equals 4 all the time Display resolution?For one decimal is 0.1; for two decimal is 0.01; for three decimal is 0.001. Let F = multiply factor / divide factorThe impulse numbers from encoder multiply F equals to display value, for example: Metric?Screw pit

7、 automatic positioning, it may have a deviation between the target position and the actual position. If the deviation is in what we hope accuracy range, it is thought to have been in place, the system output IP(In Place) signal, or it is thought to have not been in place, the actual position display
8、 will be flashing. Here, we call the deviation as positioning tolerances. Pn-007X axis positioning mode 0: two-side positioning. 1: one-side positioning. Set to one-side positioning, the system has always been in position from big to the direction of the small positioning. If the target is greater t

The positioning way can effectively eliminate ball screw transmission clearance. Pn-008X axis over distance When localizat
10、ion mode is set to 1 (one - side positioning), the system has always reaching the destination from big value position to small value position. If the target is greater than the current position, the system will run more than the target position first, and then back to the target position. We called
11、this extra distance as over distance. Pn-009X axis automatic find reference when power on 0: System does not automatically find the reference after power on; 1: System automatically finds the reference after power on. Pn-010X axis Position of reference This parameter indicates the position value of

Pn-016Wait time of retract During the shearing, after the metal plate is clamped, the backgauge motor will retract before the shearing. This can protect the backgauge efficiently. Begin 17from the Up-Dead point, system count the time, if the time is reached, system begin the retract. We called this time as wait time of retract.
