Fanuc alarm SP1996: SPINDLE PARAMETER SETTING ERROR
spindle alarm (parameter) · Fanuc 0i-D
What it means
An illegal spindle motor allocation was detected, or the configured number of spindles exceeds the maximum supported by the system. The combination of parameters No.3701#1/#4/#5, No.3716 and No.3717 does not define a valid spindle configuration.
Likely causes
- Parameters corrupted by a bad memory clear or failed data restore
- Motor model/type number (No.3716/3717) inconsistent with installed amplifiers
- Too many serial spindles declared for the path
Triage note: Correct the parameter set; no hardware action implied.
