Note 1. Set alarm output sequence at Func2 Bit6 of Mode2-Page3.
When Func2 Bit6 = “0”, CODE is displayed, and when Func2 Bit6 = “1”, BIT is displayed.
Note 2. “0” and “1” in the alarm output are:
“0” = Output is short-circuit, “1” = Output is open, when Mode2 Page3 Func2 Bit7 = “0”
“0” = Output is open, “1” = Output is short-circuit, when Mode2 Page3 Func2 Bit7 = “1”.
3. Precautions
1) This function only outputs warning, and does not execute sequence process such as Servo OFF in
the alarm output or dynamic brake stop. In case of overload warning output, prevent overload alarm
by reviewing the system operation cycle etc.
2) Warning output recovers automatically when the estimated motor temperature becomes lower than
the set value for warning output (Overload alarm is not canceled without alarm reset procedure).
Even in SOFF status, warning is output if the estimated motor temperature is higher than the set
value.
3) When this function is validated, estimated motor temperature becomes Cold Start (Estimated motor
temperature is 0% of the overload alarm level when the control power is turned on). Do not restart
the system immediately after the power turn ON and OFF due to overload alarm, since the motor may
not be cool enough. Otherwise, it may lead to burnt or damage of the motor or an accident.
Secure enough time before restarting the system.
4) When overload warning and overtravel warning occur simultaneously, overtravel warning is prioritized
in the 7-segment LED display.
