Note the following when connecting separate power supplies to control circuit power supply terminals
(R0 and T0) and main circuit power supply terminals (R, S, and T):
- Use a cable thicker than 1.25 mm
- Connect a 3 A fuse in the control circuit power supply line.( Tightening torque:1.2Nm,max
torque:1.4Nm)
- If the control circuit power supply (connected to R0 and T0) is turned on earlier than the main circuit
power supply (connected to R, S, and T), ground fault is not checked at power-on.
- When supplying DC power to the control circuit power supply terminals (R0 and T0), specify "00" as
the "a/b (NO/NC)" selection (function code C031 to C036) for intelligent output terminals ([11] to
[15]) and intelligent relay terminals (AL0, AL1, and AL2). If "01" is specified as the "a/b (NO/NC)"
selection, output signals may chatter when the DC power supply is shut off.
