Yaskawa SGLTW-80A600A
SGLT Series
Note: Values when the linear motor is combined with the SGDH Sigma II amplifier. 1 These values are with aluminum heatsink (170A: 254x254x25mm, 320A/460A : 400x500x40mm) mounted to the motor coil. 2 These values are with aluminum heatsink (609x762x50mm) mounted to the motor coil.
Lifecycle & replacement
Yaskawa's published discontinuation lists (checked 2026-09-01) do not assign a lifecycle status to this part number.
Servo amplifiers, motors, encoders and cables are matched sets. If this part is no longer available in its original form, the manufacturer's newer generation usually will not pair with the rest of the axis, so an upgrade normally covers the drive, motor and cables together. Send us the nameplate details and we will confirm availability of an exact spare or scope a compatible upgrade.
IAC stocks legacy spares and exchange units and quotes upgrade paths. Send us the nameplate details and we will confirm a compatible replacement.
