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!
