Yaskawa SGD7S-330A00A002 Yaskawa Sigma-7 SERVOPACK Amplifiers

Razz Middle East supplies Yaskawa Sigma-7 SERVOPACK servo amplifiers in Saudi Arabia. SGD7S single-axis and SGD7W two-axis amplifiers are the current generation of Yaskawa's rotary servo platform, used on packaging, converting, machine tool and robotic axes. Units are sourced to order against the complete SGD7 model code and delivered duty-paid, normally within three weeks.

About Yaskawa Sigma-7 SERVOPACK Amplifiers

Sigma-7 is the generation that followed Sigma-5, and SGD7S is its single-axis amplifier; SGD7W is the two-axis version that shares a common power stage between two motors. The model code is read field by field. In SGD7S-2R8A00A, SGD7S names the series and axis count, 2R8A is the rated output current code — the letter R marks the decimal point, so R70A, R90A, 1R6A, 2R8A and 5R5A are ascending current ratings in the same voltage class — and the characters after it set the supply voltage class, the command interface and the design revision. Interface is the field that determines whether a unit will work in a given machine: Sigma-7 amplifiers exist as analogue and pulse-train units, as MECHATROLINK-III network units, and as EtherCAT units, and a controller expecting one will not talk to another. Sigma-7 pairs with Sigma-7 motors carrying serial absolute encoders; it will not run a Sigma-II or Sigma-III motor, and the tuning, safe-torque-off wiring and setup software differ from Sigma-5.

Yaskawa Sigma-7 SERVOPACK Amplifiers in Saudi Arabia

Sigma-7 axes reach Saudi Arabia almost entirely inside new imported machinery, so the installed base is younger and more concentrated than the older Sigma generations. It is found on recent packaging, filling and labelling lines in food and beverage plants, on converting and printing machinery, on pick-and-place and palletising robots in distribution and e-commerce warehouses, and on CNC and special-purpose machine tools in fabrication shops working for Aramco and SABIC contractors. Because the machines are newer, a purchase usually follows a failure after warranty or an axis added to an existing line. Panel environment is the practical Saudi issue: Sigma-7 amplifiers derate above their rated ambient, and cabinet cooling in unconditioned halls needs checking before a repeat failure is blamed on the unit. Machine supply is normally 380/400 V at 60 Hz, and where a 200 V class amplifier is fitted it sits behind a machine transformer that must be confirmed before ordering.

Ordering and lead time

Order by the full SGD7S or SGD7W code from the amplifier nameplate and send the model code of the motor it drives. Yaskawa pairs amplifier and motor on rated output, voltage class and encoder type, and a mismatched pair will fault on power-up rather than run badly. State the command interface the machine controller uses — analogue, pulse train, MECHATROLINK-III or EtherCAT — because two units with identical current codes and different interface characters are different products. Note any fitted option module, safety card, regenerative resistor or EMC filter, all of which carry their own order codes. If you are replacing a Sigma-5 SGDV unit with Sigma-7, tell us, so we can flag the motor, cable and software changes that go with it. Amplifiers are supplied on order and delivered duty-paid, normally three weeks from confirmation.
