Servo replacements are a system decision

On a servo axis the amplifier, motor, encoder and cables are a matched set. When a legacy component fails, the manufacturer's current generation usually does not pair with the rest of the original set, so the whole axis typically has to be upgraded together: drive, motor and cables, and often controller parameters or firmware. Replacing only the failed unit is rarely possible. Before ordering, talk to us: we can quote a like-for-like legacy spare or exchange unit to keep the existing installation running, or engineer a matched upgrade path for the axis.

IAC stocks legacy spares and exchange units and quotes upgrade paths. Send us the nameplate details and we will confirm a compatible replacement.
