6.2 Test Run
CAUTION
Check the following before and during the test run.
Otherwise, there is a danger of machine breakage.
• Was the direction of the motor correct?
• Was the inverter tripped during acceleration or deceleration?
• Were the SPEED (rpm) and frequency meter correct?
• Were there any abnormal motor vibrations or noise?
When overcurrent tripping or overvoltage tripping occurs during the test run, increase
the acceleration time or deceleration time.
Maximum frequency: 60 Hz
Forward operation
Factory settings
*: For sink type wiring.
An example of a general connection diagram is shown below.
Operating with digital operator:
When setting frequency, run and stop
with digital operator.
(The same way as remote operator
(DOP) or copy with (DRW).)
Running from external command:
When setting frequency, run and stop
from external command (FW,RV Terminal.)
