官方故障排除步驟
Code type: Alarm / minor fault Manual section: Yaskawa A1000 Troubleshooting The proper braking resistor has not been installed. Select the optimal braking resistor. Use a regen converter, regen unit, braking unit, or other device to connect the +1 or +3 terminal to the - terminal. Set L8-55 to 0 to disable Internal Braking Transistor Protection. The braking transistor's use rate is high (i.e., the regen converter is large or the repetition frequency is high). - Change to a CDBR type braking unit. - Change to a regen converter. - Increase the deceleration time. The braking transistor inside the drive is faulty. Replace the drive.
