1.1 Internal block diagram

Verify the power specification
of the motor cooling fan when
performing wiring.
Refer to page 196.
Avoid frequent ON-OFF.
Repeated inrush current at power on
will shorten the converter life.
(switching life is about 100,000 times)

CAUTION
1. The 18.5K or more is not equipped with the built-in brake resistor and brake transistor marked *. The brake transistor is
provided for the 15K or less and the built-in brake resistor for the 5.5K or less.
2. Always earth (ground) the inverter and motor.
3. **: When using an external thermal relay protection, set "1" (external thermal relay valid) in Pr. 876. (factory setting)
