7:High limit frequency arriving
When the drive‘s output frequency reaches high limit frequency, the
terminal outputs indication signal.
7
8: Low limit frequency arriving
When the drive‘s output frequency reaches low limit frequency, the terminal
outputs indication signal.

9: Overload signal
When overload occurs, the terminal outputs indication signal.

10: Over current stall
When over current stall occurs in running state, terminal outputs indication
signal.

11: Over voltage stall
When over voltage stall occurs in running state, the terminal outputs
indication signal.

12: External stopping command
During running process, when external fault signal is received by the digital
input terminals, the drive reports ER11 fault, and the terminal outputs
indication signal at the same time.
