100% = smd rated output current
• Triggers 0C6 fault when motor current
exceeds c20 for too long
• Correct setting = (motor nameplate
current) / (smd output current rating) X
100%
• Example: motor = 6.4 amps and smd =
7.0 amps; correct setting = 91%
(6.4 / 7.0 = 0.91 x 100% = 91%)
WARNING!
Maximum setting is rated motor current (see nameplate). Does not provide full
motor protection!
