 Ground terminal for drive chassis (case). 

 
 

(1)  Main power supply input terminal  

 

3-phase 230V [L1/R,L2/S,L3/T] 
Single-phase 230V [L1/L,L2/N] 

1  Connect the main power supply input terminals to the 

power supply via a molded case circuit breaker for circuit 
protection or earth leakage circuit breaker.  An earth-
leakage circuit breaker which can also  detect DC current 
is recommended.  Phase-sequence matching is unneces-
sary. 

2  It is recommended that a magnetic contactor is connected 

to prevent any failure or accident from becoming serious 
by disconnecting the drive from the power supply when 
the drive protective function operates. 

3  Do not turn on or off the main power supply to start or stop 

the drive; instead, use the control circuit terminal 
FWD/REV or the RUN/STOP key on the keypad panel.  If 
it is unavoidable to turn the main power supply on or off to 
start or stop the drive, it must not exceed once per hour. 

 
(2)  Drive output terminal [U, V, W] 

1  Connect these terminals to the 3-phase motor with the correct phase-sequence.  If a motor rota-

tion direction does not correspond to the correct rotation direction, exchange any two of the U, V, 
and W phases. 

2  Do not connect a phase-advance capacitor or surge absorber to the drive output.   

3  A very long wiring length between the drive and the motor causes a high frequency current to 

flow due to floating capacity between cables, making the drive trip, increasing the leakage 
current and deteriorating the accuracy in the current display.  To prevent such trouble, the wir-
ing length to the motor should not exceed 165 feet (50 m). 

When the drive is operated in the low noise mode (carrier frequency: 8 to 15 kHz) and the wir-
ing length is long, add an optional output circuit filter.
