53
It is used to set the accumulative running time threshold of the Frequency inverter. If the accumulative
running time (b9-09) reaches the value set in this parameter, the corresponding DO terminal becomes ON.

Default
b2-22
Action after running time
reached
0: Continue to run
1: Stop
0
This function is used to define the action after b2-21 preset time reached. Setting 0 inverter will continue
work after present running time reached; and set 1, the inverter will stop.

b2-23 Cooling
fan
control
0: Fan working during running
1: Fan working during power on
0
It is used to set the working mode of the cooling fan. If this parameter is set to 0, the fan works when the
frequency inverter is in running state. When the frequency inverter stops, the cooling fan works if the
heatsink temperature is higher than 40°C, and stops working if the heatsink temperature is lower than 40°C.
If this parameter is set to 1, the cooling fan keeps working after power-on.

b2-27
Wakeup delay time

0.0s
These parameters are used to implement the dormant and wakeup functions in the water supply application.
When the frequency inverter is in running state, the frequency inverter enters the dormant state and stops
automatically after the dormant delay time (b2-25) if the set frequency is lower than or equal to the dormant
frequency (b2-24).
When the frequency inverter is in dormant state and the present running command is effective, the frequency
inverters starts up after the wakeup delay time (b2-27) if the set frequency is higher than or equal to the
wakeup frequency (b2-26).
Generally, set the wakeup frequency should be equal to or higher than the dormant frequency. If the wakeup
frequency and dormant frequency are set to 0, the dormant and wakeup functions are disabled.
When the dormant function is enabled, if the frequency source is PID, whether PID operation is performed
in the dormant state is determined by C0-27. In this case, select PID operation enabled in the stop state
(C0-27 = 1).

Timing duration

0.0 min
These parameters are used to implement the frequency inverter timing function.
If b2-28 is set to 1, the frequency inverter starts to time at startup. When the set timing duration reached, the
frequency inverter stops automatically, and meanwhile the corresponding DO outputs ON signal.
The frequency inverter starts timing from 0.0min each time it starts up and the remaining timing duration can
be checked by U0-20.
The timing duration is set in b2-29 and b2-30, in unit of minute.

b2-32 Startup
protection
0: No
1: Yes
0
This parameter is used to enable the frequency inverter safety protection. If it is set to 1, the frequency
inverter does not respond to the run command after power-on (for example, an input terminal is ON before
power-on). The frequency inverter responds only after the run command is cancelled and becomes valid
again.
In addition, the frequency inverter does not respond to the run command valid from fault reset of the
frequency inverter. The run protection can be disabled only after the run command is cancelled one time.
In this way, the motor will not automatically startup to avoid unexpected dangerous conditions for these
startup commands from power-on and fault reset.
5.4 Group b3: Input Terminals
The EM11 provides six digital input (DI) terminals (DI6 can be used for high-speed pulse input) and two
analog input (AI) terminals. The optional extension card provides another six DI terminals (DI7 to DI12) and
one AI terminal (AI3).
