Changing parameters

Before you change Pr.7 and Pr.8, you must switch to the PU operation mode. Switch to the PU operation mode and change them. More Details >>

FR-RC selection

1. The 100% braking torque means the 100% motor rated torque. Do not consider the continuous regenerative driving based on the braking torque. Consider the r... More Details >>

Relationship between frequency and output torque

Using shielded wires for frequency meter connection

Connect the shield to the terminal SD. More Details >>

FR-CV

Use the FR-HC to suppress harmonics. It also supports power supply regenerative driving.The FR-CV and FR-RC are both power supply regeneration units.The diff... More Details >>

Stop-on-contact control

1. You can implement stop-on-contact.2. When implementing stop-on-contact, use the inverter to decelerate the motors to reduce the impact upon stop-on-contac... More Details >>

Permissible brake duty

When consuming the regenerative power with the brake resistor, the brake transistor is triggered at a certain voltage to make the brake resistor use the rege... More Details >>

Brake sequence function

Since the brake sequence function requires Advanced magnetic flux vector control and advanced flux control is applied to 0.4 kW or higher motors, you cannot ... More Details >>

Thermal characteristics of motor

Basically, when the motor temperature goes higher, the motor rotation speed goes lower.The motor rotation speed also changes when the inverter input power su... More Details >>
