Wiring Precautions:
Keep the six power lines R, S, T and U, V, W away from other signal lines, at least a 30 cm distance if possible.
When the power is cut off,
the drive's internal capacitor still contains a large amount of charge--
do NOT
touch the six power lines R, S, T, and U, V, W. Please wait until the charging light goes out.
When lengthening the encoder cable, apply twisted pair cabling to the encoder cable and the grounding
signal cable. Do not exceed a length of 20 m (65.62 in or 14 ft); if it is absolutely necessary to do so, please use
a signal line with twice the wire diameter in order to minimize signal attenuation.
Please wire according to relevant regulations. Select the wire diameter according to motor wattage, as
follows:
Type
Wattage
Wire Diameter
Axial
100W~850W
20AWG
850W~7.5kW
16AWG
Spindle
7.5kW and below
