Lifecycle & replacement
Lifecycle status not indexed
No manufacturer-published lifecycle data for B&R part numbers is indexed here yet. Ask IAC to check availability and an upgrade path.
Replacing or upgrading a servo component?
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.
