Omron SGDV-2R8AE1A Omron-Listed Sigma SERVOPACK Amplifiers

Razz Middle East supplies the two Sigma series servo amplifiers catalogued under Omron, SGDV-2R8AE1A and SGDV-5R5AE1A. These are Sigma-5 generation SERVOPACK units that drive a matched rotary servo motor and close its position, speed and torque loops. Both are sourced to order against the full model code and delivered duty-paid, normally within three weeks.

About Omron-Listed Sigma SERVOPACK Amplifiers

A SERVOPACK is the amplifier half of a servo axis: it rectifies the incoming AC supply, drives a permanent-magnet servo motor and closes the control loops from the motor's encoder. In the SGDV code, SGDV names the Sigma-5 generation, the following characters are the rated output current code where the letter R marks a decimal point — so 2R8A sits below 5R5A in the same voltage class — and the remaining characters set the supply voltage class, the command interface and the design revision. The interface field is the one that decides compatibility: Sigma-5 amplifiers were built as analogue speed and torque units, pulse-train position units and MECHATROLINK network units, and a controller built for one will not drive another. The amplifier is matched to its motor on rated output, voltage class and encoder generation, so the two are normally specified and replaced together rather than individually.

Omron-Listed Sigma SERVOPACK Amplifiers in Saudi Arabia

Amplifiers of this size sit on small positioning axes inside imported machinery, not in general electrical distribution, so in Saudi Arabia they are found on food and beverage packaging lines, on labelling and cartoning machines, on small converting and printing equipment, and on assembly, test and inspection rigs in pharmaceutical and light manufacturing plants around Riyadh, Jeddah and Dammam. Demand is reactive: the unit is bought because an axis has faulted and a line is stopped. Two local conditions are worth checking before ordering. Cabinet ambient temperature in unconditioned halls pushes amplifiers into derating and shortens their life, and dust in cement, mining and coastal environments does the same. Mains are 380/400 V at 60 Hz, so where a 200 V class amplifier is fitted it runs from a machine transformer that must be confirmed as part of the order.

Ordering and lead time

Order by the complete SGDV code from the amplifier's own nameplate rather than from machine documentation, which is often out of date. Send the motor model code with it: amplifier and motor are matched on rated output, voltage class and encoder generation, and a mismatched pair faults on power-up. State the command interface used by the machine controller — analogue, pulse train or MECHATROLINK — because two amplifiers with the same current code and different interface characters are different products. Mention any option card, regenerative resistor or EMC filter that is fitted, as these carry separate order codes. 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.
