DST1402 Emerson Control Techniques Digitax ST Single-Axis Servo Drive 380–480 V 3-Phase Frame 1

Product Overview: Emerson DST1402 

Parameter Specification
Manufacturer Emerson 
Order Number DST1402
Product Name Digitax ST – Single-Axis AC Servo Drive

Application & Fault Scenarios

Typical Uses: Single-axis servo control for medium-power applications on packaging, printing, filling and indexing machinery, typically paired with a Unimotor FM or equivalent brushless servo motor. Standard like-for-like exchange when an existing Digitax ST fails.
Common Field Issues:
  • Drive will not enable / trips on overcurrent → check motor cable continuity and insulation, feedback connector seating, and that motor parameters match the installed motor.
  • Overvoltage trip on deceleration → insufficient braking; fit or upgrade the external braking resistor and review deceleration ramp.
  • Position drift or axis hunting → re-run auto-tune, verify inertia ratio, encoder direction and gear-ratio settings.
  • No fieldbus communication → confirm the correct SM module is fitted, node address/parity match the master, and termination is present at both line ends.
