Causes
Remedy
 Incorrect mass load confi
gured or programmed (M37)
· Correct configuration or
program
 Gain factor set too high · Correct the parameter
 Damping factor set too low · Correct the parameter
 Signal filter factor set too high
(smoth acceleration/speed

tion)
Or very noisy acceleration sig
nal with high amplitude
· Reduce signal filter factor
· Increase signal filter factor
 Minimum mass load exceeded · Increase basic load (see sys
tem manual for the SPC200)
 Insufficient tolerance required · Increase tolerance
