NOTE 1: Common terminal for each terminal is different.
NOTE 2: The regenerative resistor has a temperature sensor.
When it works, turn off power supply to the inverter
o set the deceleration time longer.
*: P24 is for source type wiring.
NOTE 4: Do not input the operation command
simultaneously when the main circuit
is turned on.
NOTE 3: When the operation command is input first
and the main circuit power is turned ON,
and direct start results and a trip occurs.
