Safety-Slip: Each drive-module includes an integrated stepper motor that slips if max torque limits are exceeded. No mechanical slippage, only electro magnetic. If a slip occurs, output torque drops very low and motor current drops slightly; then column realignment commences automatically while the rest of the sign continues normal operation.
