Yaskawa SGDH-02AE Yaskawa Sigma SERVOPACK Servo Amplifiers

Razz Middle East supplies Yaskawa Sigma series SERVOPACK servo amplifiers across Saudi Arabia. The family spans the original SGD units, SGDM and SGDH, SGDS from the Sigma-III generation, and the SGDV Sigma-5 amplifiers together with their converter and option modules. Amplifiers are sourced to order against the exact model code and delivered duty-paid, normally within three weeks.

About Yaskawa Sigma SERVOPACK Servo Amplifiers

A SERVOPACK is the amplifier half of a Yaskawa servo axis: it takes the incoming AC supply, drives the permanent-magnet servo motor and closes the position, speed and torque loops using the motor's encoder feedback. The model code fixes what the unit can do. In SGDV-R70A11B, SGDV names the Sigma-5 generation, R70A is the rated output current code where the letter R marks a decimal point, and the trailing characters set the supply voltage class, the interface type and the design revision. Interface is the field that most often catches people out: the same current rating exists as an analogue speed and torque unit, a pulse-train position unit, and MECHATROLINK-II or MECHATROLINK-III network units, and they are not interchangeable with each other or with the machine's controller. Converter and option references such as SGDV-OCA01A and SGDV-OCA03A are separate order codes for the units and boards that go with an amplifier rather than amplifiers themselves. Earlier SGD, SGDA, SGDM and SGDS generations use their own code layouts and their own encoder protocols, which is why a Sigma-III amplifier will not run a Sigma-5 motor.

Yaskawa Sigma SERVOPACK Servo Amplifiers in Saudi Arabia

SERVOPACK amplifiers are found in Saudi Arabia inside imported production machinery rather than in general electrical distribution. Packaging and filling lines in food and beverage plants, plastics converting and printing machinery, machine tools in fabrication shops, and robotic palletisers in distribution centres are the main hosts. They also appear on test rigs in petrochemical and pharmaceutical facilities. The amplifier is usually replaced with the line already stopped, which makes identifying the exact interface variant the critical step. Cabinet conditions are a real factor in the Kingdom: SERVOPACKs are sensitive to ambient temperature and to dust, and units in unconditioned machine halls or in cement and mining environments fail earlier than the same unit in a cooled panel. Supply is 380/400 V at 60 Hz, so a 200 V class amplifier in an imported machine sits behind a matching transformer, and that has to be confirmed before a 400 V class replacement is ordered.

Ordering and lead time

Send the complete model code from the amplifier's own nameplate, not from the machine documentation, and send the motor's model code with it. The amplifier and motor are matched on rated output, voltage class and encoder generation, and Yaskawa's own selection rules pair specific codes. State the control interface the machine controller uses — analogue, pulse train, MECHATROLINK-II or MECHATROLINK-III — because the current rating alone does not identify the unit. Tell us whether option cards, a regenerative resistor or an EMC filter are fitted, as these carry separate order codes. Where the original is an obsolete SGD, SGDM or SGDS unit, we will say whether a same-generation part can still be sourced or whether the axis has to be migrated to Sigma-5 or Sigma-7 along with the motor. Units are supplied on order and delivered duty-paid, normally three weeks from confirmation.

Specifications are taken from the supplier's published catalogue data. Confirm against the manufacturer's current datasheet before ordering.
