• Automatic motor braking below 0.1 Hz
by means of motor DC current for the
entire holding time (afterwards: U, V,

• Confirm motor suitability for use with
DC braking

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%)
NOTE
Do not set above the rated motor current as listed on the motor dataplate. The
motor thermal overload function is UL approved as a motor protection device. If
line power is cycled, the motor thermal state is reset to cold state. Cycling power
after an overload fault may result in reducing the motor life.
