ABB SCA1390

Product Introduction:

The ABB SCA1390 is a compact single-axis servo drive designed for high-performance motion control in machine automation — including packaging, textile, printing, and electronics assembly lines. It forms part of ABB’s servo system solution together with ABB servo motors (HDS/eSM series). The drive supports torque, speed, and position control modes via analog reference, pulse & direction, or fieldbus communication.

Category: ABB

Description

Key Features:

Four-quadrant regenerative PWM operation
Built-in PI current and velocity loops with auto-tuning capability
Safe Torque Off (STO) functional safety option on later variants
Supports resolver, incremental encoder, or absolute encoder feedback
DIN-rail or panel mounting; fanless convection cooling in lower power ratings

Technical Specifications:

Supply Voltage: 1×230 VAC or 3×230/400 VAC (model dependent)
Rated Current: Typically 3 A – 9 A continuous (depending on sub-variant)
Peak Current: Up to 2× continuous rating for short duration
Control Modes: Torque, Velocity, Position (PTI / CW/CCW Pulse / Analog ±10 V)
Feedback Interfaces: Encoder (RS422 differential A/B/Z), Resolver, SSI, EnDat (variant-specific)
Communication: CANopen / Profibus-DP / EtherCAT / Modbus (option cards)
Digital I/O: 4–8 configurable digital inputs, 2–4 digital outputs
Analog I/O: ±10 V reference input, monitor outputs
Protection: Over-current, over-voltage, under-voltage, over-temperature, motor short-circuit
Operating Temp.: 0 °C to +50 °C (storage –25 °C to +70 °C)
Certifications: CE, UL, cUL, RoHS

Applications: Packaging machines, labeling systems, pick-and-place robots, textile winding/unwinding, CNC auxiliary axes.

Installation Notes: Mount vertically on a grounded metal panel allowing ≥50 mm top/bottom clearance for convection cooling. Use shielded encoder cables separately routed from power cables. Ensure earth ground connection < 0.1 Ω. Verify motor inductance/current match before first power-up.
