fault when motor
current exceeds c20 for too long
• Correct setting = (motor
nameplate current) / (Tml
output current rating) X 100%
• Example:
motor = 6.4 amps
and Tml = 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!

• If motor calibration is attempted
before programming C86...C91,
triggers n1d fault
