Custom V/f Pattern

Set each pattern when using a special motor (high-speed motor, etc.) or when requiring special torque adjustment of
machine.
Make sure to satisfy the following
conditions for setting of constants
n012 to n018.
n017 < n015 < n014 < n012
Constant No.

n018
∗ For 400 V class, the value is twice that of 200 V class.
Increasing the voltage of the V/f pattern increases motor torque, but an excessive increase may cause the following:
•
Inverter malfunction because of motor overexcitation.
•
Motor overheat or excessive vibration.
Increase voltage gradually while verifying the motor current.

Reverse Run Prohibit (n006)

"Reverse run disabled" setting does not accept a reverse RUN command from the control circuit terminal or Digital
Operator. This setting is used for applications where a reverse RUN command can cause problems.
Setting
6.3.2. Multi-Step Selection
By combining frequency reference and input terminal function selections, up to four steps of speed can be set.
