DST1404 Emerson Control Techniques Digitax ST Single-Axis Servo Drive 380–480 V 3-Phase

Product Overview: Emerson DST1404 

Parameter Specification
Manufacturer Emerson 
Order Number DST1404 
Product Name Digitax ST – Single-Axis AC Servo Drive
Product Family Control Techniques Digitax ST servo drive family

Application & Fault Scenarios

Typical Uses: A single servo axis requiring more continuous current than the DST1402/DST1403 — for instance web-tension and rewinding drives, heavier indexers and larger packaging axes — typically paired with a Unimotor FM or comparable brushless motor. Also the routine exchange when an in-service Digitax ST fails.
Common Field Issues:
  • Fault on enable or overcurrent trip → check motor cable insulation and continuity, reseat the feedback connector, and confirm the stored motor data matches the motor actually installed.
  • DC-bus overvoltage on braking → fit or upgrade the external braking resistor and extend the deceleration ramp time.
  • Overshoot or axis hunting → re-run auto-tune, then review inertia ratio, encoder count direction and gear-ratio parameters.
  • Master cannot see the drive on the bus → confirm the correct SM module is fitted, node address and parity match, and termination is present at both line ends.

FAQ

Q1: What is the Emerson DST1404?
A: A Control Techniques Digitax ST single-axis servo drive with 380–480 V 3-phase input, an onboard feedback interface and two SM option slots — a higher-current variant than DST1403.
Q2: Is Emerson CT the same as Nidec CT for this drive?
A: Yes, it is the same product line under different brand ownership periods; order using the exact code printed on your existing nameplate.
Q3: Which motor pairs with it?
A: A brushless AC servo motor whose rated current fits this drive, such as Unimotor FM units in the 142/190 frame, or an equivalent third-party motor with matching feedback.
