Instruction manual

2. If the wiring distance is long, reduce the Inverter carrier

frequency as described below.

3. Set the Carrier Frequency Selection (n080) to 1, 2, 3, or 4

when using vector control mode. Do not set it to 7, 8, or 9.

4. If the Inverter repeats stops and starts with a load exceed-

ing 120% of the Inverter rated current within a cycle time

of 10 minutes or less, reduce carrier frequency at a low

speed. (Set constant n175 to 1.)

5. The carrier frequency is automatically reduced to 2.5 kHz

when the Reducing Carrier Frequency Selection at Low

Speed (n175) is set to 1 and the following conditions are

satisfied:

Output frequency ≤ 5 Hz

Output current ≥ 110%

Factory setting: 0 (Disabled)

 Operator Stop Key Selection (n007)

The Digital Operator stop button can be disabled by a

setting in the Inverter. Install a separate emergency

stop switch.

Failure to observe this warning may result in injury.
