  • Page 10 1. General The VARILIMIT VS-12PB is a positioning Controller unit which is used together with NSD’s unique ABSOCODER sensor to achieve high-precision positioning control. Applications: Transport systems, press machines, assemble equipment, and packaging equipment, etc. 1-1. Features Some of the main VS-12PB features are described below.
  • Page 11 This basic VS-12PB system configuration is shown below. ●Basic System Configuration NSD components are indicated by NSD mark. All other components must be supplied by the user. Note When the VS-T12 or VS-T12B setting display unit is used, settings cannot be specified by communications with a personal computer or programmable controller because the VS-T12 or VS-T12B uses the controller’s communication...

  • Page 12: Functions

    3. Functions 3-1. Position Setting Function 3-1-1. Automatic Positioning Function (AUTO) The ABSOCODER sensor detects the machine’s current position, and this position is compared with the target position. The motor control signals are then output according to this comparison. ●Example of Automatic Positioning Control 3-1-2.
  • Page 13 3-1-3. Speed-Switching Format With the Speed-Switching format, the speed switching signals (high-speed and low-speed) operate independently, with the high-speed signal being ON during high-speed operation, and low-speed signal being ON during lowspeed operation. ●Control Timing (For U-Turn Positioning) 3-1-4. Speed-Stepping Format With the Speed-stepping format, the high-speed, medium-speed, and low-speed signals do not operate independently.

  • Page 14: Starting Operation From Inside Stop Zone

    3-1-5. Starting Operation From Inside STOP Zone When the STOP zone is entered, the motor control signals for the positioning operation are switched OFF, and the brake is applied. With the VS-12PB unit, it is possible to start operation from inside the STOP zone if so designated at parameter No.48.

  • Page 15: Timer Settings

    3-1-6. Timer Settings (Motion Non-Detection Timer & Motion Misdirection Non-Detection Timer) The “motion non-detection timer” setting designates the period from the point when positioning begins, until the point when the motion error function begins. Motion errors are determined by a monitoring function which checks the amount of change in the current position value every 0.5 s.

  • Page 16: Learning Function

    3-1-7. Learning Function When positioning is completed, the Learning function checks the discrepancy between the target stop position and the actual stop position. It then automatically adjusts the STOP zone for the next operation based on the discrepancy. Depending on the positioning direction, either the FORWARD or REVERSE stop zone will be adjusted. (The STOP zone is not corrected for “START from STOP zone”...
  • Page 17 3-1-8. INCH Function (INCH) The INCH function compensates for positional deviations caused by machine friction, etc., by adding the preset INCH zone amount (parameter setting no.52) to the target position so that extremely low-speed positioning occurs. When executing positioning operations for press dies, this function permits corrections for minute deviations caused by machine wear and deformation, etc.

  • Page 18: Limit Switch Output Function

    3-2. Limit Switch Output Function With this function, the machine’s travel amount is detected by the ABSOCODER sensor, and external ON/OFF signal outputs are used in place of conventional limit switches. ●Limit Switch Output Example With the VS-12PB, up to 10 ON / OFF outputs per channel are possible. 3-2-1.

  • Page 19: Current Position Preset Function

    3-3. Current Position Preset Function When this function is executed (by external input), the machine’s current position will be moved (corrected) to the “PRE” position which has been pre-designated. The PRE function is enabled by “PRE input 1.2”. ●Application Example The VS-12PB automatically identifies the travel direction by comparing the current position values every 100ms.

  • Page 20: Communication Function

    The VS-12PB permits target positions and parameter settings to be specified from a programmable controller or a personal computer by using this communication function. For details, please contact your NSD sales representative. Moreover , as shown in the illustration below, up to 32 VS-12PB units can be controlled from a single host programmable controller.
