DST1403 Emerson Control Techniques Digitax ST Single-Axis Servo Drive 380–480 V 3-Phase Frame 1/2

Product Overview: Emerson DST1403 

Parameter Specification
Manufacturer Emerson 
Order Number DST1403 
Product Name Digitax ST – Single-Axis AC Servo Drive
Product Family Control Techniques Digitax ST servo drive family

Application & Fault Scenarios

Typical Uses: Suited to single servo axes needing more continuous current than the DST1402 — for example web-handling and rewinding drives, heavy indexers and larger packaging axes — usually paired with a Unimotor FM or comparable brushless motor. Also the routine swap when an in-service Digitax ST fails.
Common Field Issues:
  • Trip on enable or overcurrent → inspect motor cable insulation and continuity, reseat the feedback connector, and confirm stored motor data matches the motor actually fitted.
  • DC-bus overvoltage during braking → add or upgrade the external braking resistor and lengthen the deceleration ramp.
  • Axis overshoot or hunting → repeat the auto-tune, then review inertia ratio, encoder count direction and gear-ratio parameters.
  • Fieldbus not recognised by the master → verify the correct SM module is installed, node address and parity match, and bus termination exists at both ends.

FAQ

Q1: What is the Emerson DST1403?
A: A Control Techniques Digitax ST single-axis servo drive, 380–480 V 3-phase input, with an onboard feedback interface and two SM option slots — a higher-current variant than DST1402.
Q2: Is Emerson CT the same as Nidec CT for this drive?
A: Yes, it is the identical product line under different brand ownership periods; order using the exact code printed on your existing nameplate.
Q3: What motor should I pair it with?
A: A brushless AC servo motor whose rated current fits this drive's rating, such as Unimotor FM units in the 115/142 frame, or an equivalent third-party motor with matching feedback.
