Yaskawa SGD7S-2R8A00A002 AC Servo Drive

Description

• Model breakdown​ (SGD7S-2R8-A-00-A-002):
  • SGD7S​ = Σ-7 series single-axis SERVOPACK
  • 2R8​ = 400W class, 2.8A continuous output
  • A​ = 200V class (3-phase 200–240VAC input)
  • 00​ = Analog voltage / Pulse train command​ (no bus communication — differs from A10A=MECHATROLINK-II, A20A=MECHATROLINK-III, AA0A=EtherCAT, AC0A=PROFINET)
  • A​ = Hardware revision A
  • 002​ = Standard (some sources denote “002” as painted/coated version for light harsh environment, but Yaskawa standard catalog lists it as base analog/pulse type)
  • → SGD7S-2R8A00A002 = Σ-7 400W servo amplifier, 200V class, 2.8A cont./9.3A peak, analog voltage + pulse train command, hardware rev A, standard version
• Key performance highlights:
  • Industry-leading 3.1 kHz speed response bandwidth​ — fastest settling in class, dramatically reduces positioning time
  • 24-bit encoder feedback​ (incremental or absolute) — ultra-fine resolution for smooth, nano-level positioning
  • Tuning-less operation​ — advanced auto-tuning + vibration suppression out of the box, no manual gain adjustment needed
  • Inertia ratio tolerance up to 30:1​ — maintains tuning stability even with widely varying loads
  • IEC 61508 SIL3 / ISO 13849-1 PLe​ safety certified (with STO — Safe Torque Off)
  • Fully closed-loop capable​ (optional) — with SGDV-OF□0□A fully-closed feedback option module
• Typical paired motor: SGM7J-04AFC6S​ (400W Σ-7 servo motor, low-inertia, 24-bit encoder). Other compatible Σ-7 motors: SGM7A-04 (medium inertia), SGM7G-04 (high inertia), SGM7F-04 (flat), SGM7D (direct drive). All Σ-7 400W-class motors (rated 2.8A) work with this amplifier.

⚠️ Critical: This is the ANALOG/PULSE type, NOT a bus-type drive!

If your system uses a fieldbus, you need a different SGD7S variant:

Command Type	Model Pattern	Bus
Analog/Pulse (this one)​	SGD7S-2R8A00A002	None — pulse train + ±10V analog
MECHATROLINK-II	SGD7S-2R8A10A	MECHATROLINK-II
MECHATROLINK-III	SGD7S-2R8A20A	MECHATROLINK-III
EtherCAT	SGD7S-2R8AA0A	EtherCAT (CoE)
PROFINET	SGD7S-2R8AC0A	PROFINET
Command Option Attachable	SGD7S-2R8AE0A	Slot for option board

Don’t order this analog/pulse unit if your PLC outputs EtherCAT/MECHATROLINK — you’ll need the corresponding bus version. This SGD7S-2R8A00A002 is for pulse-train controllers​ (e.g., Panasonic FP, Keyence KV, Omron NJ/NX with pulse out, Mitsubishi FX) or analog ±10V speed/position commands​ from a motion controller.

⚠️ 200V class, NOT 100V!​ The “A” in 2R8A means 200–240V 3-phase input. There is a 100V variant: SGD7S-2R8F□□□​ (single-phase 100–120V) — physically similar but different input wiring. If your facility only has 100–120V single-phase, this 2R8A unit will NOT work — you need the 2R8F version. Most industrial sites in CN/JP/EU have 200V 3φ, so 2R8A is the standard.

Technical Specifications (SGD7S-2R8A00A002 — 400W, 200V class, Analog/Pulse)

⚠️ Wiring essentials​ (critical for first install):

• L1/L2/L3​ (main power): 3-phase 200–240VAC
• L1C/L2C​ (control power): same 200–240VAC (or bridge from L1/L2 if single-phase supply available)
• U/V/W​ → motor (SGM7x-04xx)
• PG​ → encoder feedback from motor (serial 24-bit)
• CN1​ → I/O signals (7 in + 4 out, 24VDC photocoupler)
• CN3​ → RS-422 to digital operator JUSP-OP05A-1-E or PC with SigmaWin+
• CN7​ → USB to PC (SigmaWin+)
• FG​ → ground (critical for noise immunity)
• Grounding: Class D (100Ω or less) to reduce electrical interference

⚠️ Tuning-less feature​ — you typically don’t need manual gain tuning. On first power-up with SigmaWin+, the drive auto-detects motor inertia and self-tunes. For highly dynamic applications, advanced vibration suppression, ripple compensation, and friction compensation can be enabled via parameter — no oscilloscope/experienced engineer required.

Warranty & After-Sales

• Factory new units: 12 months warranty
• Refurbished units: 3-6 months warranty (bench test with SGM7J-04 motor — power-up, SigmaWin+ connect via USB, jog forward/reverse, analog speed command response, pulse-train positioning test, STO function verify, alarm history check)
• Technical support for:
  • Analog/Pulse wiring​ (CN1 pinout: 24VDC in/out wiring, sourcing/sinking selection; ±10V analog speed command from motion controller; pulse train (CW/CCW or pulse+dir) to drive position mode; encoder feedback wiring from motor)
  • SigmaWin+ first connect​ (USB cable to CN7 → SigmaWin+ auto-detect → motor auto-ID → auto-tuning → parameter backup)
  • Motor compatibility​ (SGM7J-04AFC6S is standard 400W pairing; SGM7A-04 (medium inertia), SGM7G-04 (high inertia for flywheel/large inertia load), SGM7F-04 (thin profile) — all 2.8A rated, plug-n-play with this amplifier)
  • STO wiring​ (STO input via CN1 pins — dual-channel safety: wire to safety relay (G9SA) or safety PLC (NX+NE1A); when STO opens, drive removes torque within <1ms, SIL3/PLe compliant)
  • Replacement for older Σ-5 / Σ-7 (early): SGD7S-2R8A00A is the current 400W analog/pulse model; if you have an older SGD7S-2R8A00A (without “002” suffix), this 002 is the direct replacement (minor HW rev, fully backward-compatible parameters). For Σ-5 SGDV-2R8A01A, migration requires parameter remap (Σ-7 has enhanced tuning, but most params translate).
  • Common fault codes​ (A.510 over-speed, A.b33 current detection, A.020 servo alarm, A.710 over-voltage, A.730 regen error) — we can diagnose remotely via SigmaWin+ alarm history export
• Optional: SGM7J-04AFC6S motor (400W paired), JUSP-OP05A-1-E digital operator, Sigma-7 power/encoder cable sets (peripheral selection manual SIEPS80000132), 200V 3φ circuit breaker, 24VDC DIN PSU for I/O, STO safety relay (G9SA), USB cable for CN7, regenerative resistor (external, if application requires heavy braking)

Applications

• Precision Positioning Stage (Semiconductor / PCB): 400W SGM7J-04 motor + SGD7S-2R8A00A002 in pulse-train mode — 24-bit encoder gives sub-micron repeatability; 3.1kHz bandwidth enables fast settle for high-throughput pick-and-place. Tuning-less auto-tune handles varying payloads (different nozzle weights) without re-tuning.
• OEM Machinery Retrofit (Analog ±10V Speed Command): Many existing machines have an analog motion controller (e.g., old Keyence KV, Omron CJ1W-DA, Mitsubishi FX-DA) outputting ±10V speed command — this SGD7S-2R8A00A002 directly accepts that analog signal (no PLC upgrade needed). Drop-in replacement for aging Σ-5 SGDV-2R8A01A or even earlier Σ-3 SGDS-02A01A.
• Robotics / Small 6-Axis Joint: 400W servo for robot elbow/wrist joint — 2.8A continuous / 9.3A peak handles dynamic acceleration; STO built-in means safety relay chain can directly cut torque for e-stop category 0 stop.
• Conveyor / Indexing Table: Pulse-train from PLC (e.g., Omron CP1H/CP1L 100kHz pulse out) → SGD7S-2R8A00A002 → SGM7J-04 motor drives indexing table. 1:5000 speed range and ±0.01% speed stability ensure precise index dwell.
• Packaging / Labeling Machine: 400W axis for cutter/feeder — 3.1kHz bandwidth tracks fast cyclic motion; tuning-less suppresses mechanical resonance from belt/cam; STO integrates with guard door interlock.
