S661 Controller Manual Exclusive

  • Pn200 (Electronic Gear Ratio Numerator): Critical for synchronizing motor rotation with input pulses.
  • Pn201 (Electronic Gear Ratio Denominator):

    • Before attempting to program or wire the unit, proper identification is required. The S661 is generally identified as a Hybrid Servo/Stepper Drive with Built-in PLC Logic.

    Use the WREG function in Ladder Logic:

    LD IR33   // Load Temperature
GT K70    // Greater than 70c?
OUT OR40  // Trigger pre-alarm relay

    The standard manual would flag IR33 as an "Invalid Address." Ignore that error. The compiler accepts it if you disable "Strict Address Checking" in the system flags (Flag 101). s661 controller manual exclusive
