*1 The cables used should be 75°C (167°F) copper cables.
*2 The terminal screw size indicates the terminal size for R/L1, S/L2, T/L3, U, V, W, a screw for earthing (grounding), and P/+ for option connection.
A screw for earthing (grounding) of the 02210 or more is indicated in ( ).
The line voltage drop can be calculated by the following formula:
3 × wire resistance[mΩ/m] × wiring distance[m] × current[A]
line voltage drop [V]=
Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque
reduction) in the low speed range.
CAUTION
· Tighten the terminal screw to the specified torque.
A screw that has been tighten too loosely can cause a short circuit or malfunction.
A screw that has been tighten too tightly can cause a short circuit or malfunction due to the unit breakage.
· Use crimping terminals with insulation sleeve to wire the power supply and motor.
