  • Page 6: Protocol

    N 152 3.2. Protocol The spindle position display operates with ASCII protocol (clear text protocol). Depending on the command, the protocol data package varies between 5 and 17 bytes. Byte Hex code Significance Values SOH = start of heading permanent 01h Adr = identifier 00...31dez + 20h offset (identifier 00 = 20h)

  • Page 7: Data Saving

    N 152 3.6. Data saving Specific parameters are saved in EEPROM (1.000.000 writing cycles). Data saving is via interface upon every parameter transmission to SPA. Important: There should not be a cyclic transmission of these parameters to SPA but only if necessary, for example in case of parameter alteration.

  • Page 8: Command Explanations

    N 152 4. Command explanations 4.1. General information The following is describing the individual interface commands broken down into the four groups below: operating commands [ commands required during operation ] parameter commands [ commands for SPA parameterization ] identifier commands...
  • Page 9 N 152 Command extension Check Position „CX“ Command extension „Check Position CX “provides besides the alignment status target versus current value also the contents of the status and error register as well as the current value. The profile number is not transmitted.
  • Page 10 N 152 Motor holding torque on / off „DB“ (44h, 42h) Prior to utilizing “DB” command to activate / deactivate the holding torque it must be enabled first in command „m“ since otherwise command „DB“ remains ineffective. Holding torque ever ON means that only motive shaft positioning operations are possible - either by aid of the two keys provided or by a corresponding command via interface.
  • Page 11 (2Dh) together with 5 data bytes is replied. Positive values are represented by 6 data bytes without sign. Values inferior to 5(4) digits will come with preceding zeroes. Please note that N 152 provides a 5-digit actual value.
  • Page 12 N 152 4.2.5. Read / write target profile „S“ (53h) This command is utilized to read the presently active target (profile value) respectively to read or write a specific target. Data are composed by profile number (2 bytes) and target (6 bytes). Note: Negative targets are transmitted as 5-digit number (see example 3).
  • Page 13 N 152 Transmitting targets with simultaneous motor start signal Specific applications require autonomous re-alignment of shafts to the new target when it is received without prior enable signal by command „D“. For this intention the following commands are available: SPF transmits to SPA profile number together with motor start signal for automated positioning operations SDF transmits to SPA position value together with motor start signal for automated positioning operations The addressed SPA is enabled by adding sub-command „F“...
  • Page 14 N 152 4.2.8. 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.

    N 152 4.2.9. Indicate optional column of figures in upper line „t“ (74h) This command is utilized to indicate a 5-digit number in the upper line of the display. The numerical column is indicated less dot respectively comma. Preceding zeroes as well as both arrows are suppressed. The bottom line still indicates the actual value.
  • Page 16 N 152 4.3.1. Read / write bit parameters „a“ (61h) To exploit maximum memory capacity, several parameters are put together and transferred as “data pack” under the following parameter codes: Data1: 1 0 X X 0 X 0 X ┬ ──┬── ─┬─ ─┬─...
  • Page 17 N 152 Counting mode This parameter assigns either „ascending“ or „descending” counted values in relation to the shaft’s direction of rotation. Following parameters are available: 00 = Up Clockwise rotation, ascending counted values 01 = Down Clockwise rotation, descending counted values...
  • Page 18 N 152 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.
  • Page 19 N 152 Significance of parameter „m“ Key assignment This parameter assigns a specified direction of rotation to a certain key. For the mounting option “keypad below display” and the remaining default parameters applies the following: 0 = Up left/right key actuation = shaft rotation ccw/cw, counting mode UP/DOWN...
  • Page 20 N 152 Holding torque This parameter is utilized to enable respectively disable the motor holding torque. Both directional signals “motor ccw” and “motor cw” are activated by the spindle position display (SPA). Thus, the motor is hold at its actual position.
