Page 6: Data Transmission Properties
Some specific commands are designated so-called broadcast commands. As soon as the master broadcasts a command to identifier 99, the command is addressed to every N 150 in the network. Each individual spindle position display will accomplish the respective command but will not respond any confirmation to master. - Page 7 In case of a negative value, the “minus“ sign (2Dh) together with 5 data bytes is replied. Positive values are represented by 6 data bytes without sign. Values of less than 5 (4) digits will come with preceding zeroes. Please note that N 150 provides a 5-digit actual value. Example: Actual value = -32.50 Transmission Actual value = –32.50...

- Page 9 N 150 4.2.6. Set actual value as preset „Z“ (5Ah) Command “Z” is utilized to set the actual value at any optional value. The required position value is transmitted to SPA. The SPA will calculate a so-called “preset offset” value relating to the true absolute encoder position.
- Page 10 N 150 4.2.8. Indicate optional column of figures in bottom line „u“ (75h) The command is utilized to indicate a 5-digit column of figures in the bottom line of the display. The number is indicated less dot respectively comma. Preceding zeroes as well as both arrows are suppressed. The upper line still indicates the actual target or column of figures.

Page 11: Parameter Commands
N 150 4.3. Parameter commands Command Data amount read write Broad- Save in Significance code in bytes cast EEPROM a (61h) Read/write general parameters b (62h) Parameter: Tolerance compensation, window c (63h) Parameter: scaling of spindle pitch i (69h) Parameter: mm / inch 4.3.1. - Page 12 N 150 Significance of parameter „a“ Positioning direction Positioning direction This parameter defines the direction the target is aimed for. Tolerances that occur for example at cogwheels, joints, shafts etc during a precise positioning operation requires a tolerance compensation. The tolerance compensation is proceeded by aiming for the target position always from the same direction utilizing so-called loops.
- Page 13 N 150 Resolution This parameter defines the resolution of the actual value. Upon altering the resolution the decimal point is shifted correspondingly by one digit to the right or left, same applies also to actual value and target. The target values however are not converted correspondingly but only the decimal point is shifted.
