Settings Function Description
0
No Function
1 AC Drive Operational
Active when the drive is ready or RUN command is “ON”.
2 Master Frequency Attained
Active when the AC motor drive reaches the output frequency
setting.
3 Zero Speed
Active when Command Frequency is lower than the Minimum
Output Frequency.
4 Over-Torque Detection
Active as long as over-torque is detected. (Refer to Pr.06.03 ~
