Figure 3.1 Standard Drive Connection Diagram
*1 Set the wiring sequence to de-energize the drive with the MFDO. If the drive outputs a fault during fault restart when you use the
fault restart function, set L5-02 = 1 [Fault Contact at Restart Select = Always Active] to de-energize the drive. Be careful when you
use a cut-off sequence. The default setting for L5-02 is 0 [Active Only when Not Restarting].
*2 When you install a DC reactor, you must remove the jumper between terminals +1 and +2.
*3 When you use a regenerative converter, regenerative unit, braking resistor, or braking resistor unit, set L3-04 = 0 [Stall Prevention
during Decel = Disabled]. If L3-04 = 1 [General Purpose], the drive could possibly not stop in the specified deceleration time.
*4 Cooling fan wiring is not necessary for self-cooling motors.
*5 Connect peripheral options to terminals -, +1, +2, B1, and B2.
WARNING! Fire Hazard. Only connect factory-recommended devices or circuits to drive terminals B1, B2, -, +1, and +2.
Do not connect an AC power supply lines to these terminals. Incorrect wiring can cause damage to the drive and serious
injury or death from fire.
