Parameter Description / Typical Specification Product Type Soft Starter (Control Unit + Separate Power Unit) Series Altivar Process ATS22 Supply Voltage Standard: 208-480V AC, 3-phase, 50/60 Hz (for "S6" in the code). Other voltage codes exist (e.g., Q for 575V, T for 690V). Verify based on the full part number of the power unit. Motor Power Rating Depends entirely on the paired Power Unit. For example, with a 480V supply: • ATS22D17S6U power unit → ~ 17A (approx. 7.5 HP / 5.5 kW) • ATS22D32S6U power unit → ~ 32A (approx. 15 HP / 11 kW) • ATS22D47S6U power unit → ~ 47A (approx. 25 HP / 18.5 kW) Note: "C41" is the control unit; "Dxx" indicates the power unit current rating. Control Method Voltage ramp, Torque control, Pump/Fan control (selectable) Communication Ports Integrated serial communication. Typically supports Modbus (RS-485) and CANopen. Control Voltage Typically 24V DC (sourced from the power unit or external). Protection Features Motor overload, Phase loss/unbalance, Locked rotor, Undercurrent, Overcurrent, Control unit self-protection. Enclosure The control unit (C41) is typically a board-mounted or DIN-rail mounted module. The power unit has its own enclosure (IP00/open-type or IP20 with a cover). Standards & Compliance CE, UL, cUL, RoHS compliant. Designed to meet international industrial standards.
