☆
75°C 0–100°C
Module temperature
threshold
P8-47
When the heatsink temperature of the AC drive reaches the value of this parameter, the
corresponding DO becomes ON, indicating that the module temperature reaches the
threshold.

0
0: Fan working during running
1: Fan working continuously
Cooling fan control P8-48
It is used to set the working mode of the cooling fan. If this parameter is set to 0, the fan
works when the AC drive is in running state. When the AC drive 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.

Dormant(Sleeping)
delay time
P8-52
These parameters are used to implement the dormant and wakeup functions in the water
supply application.
When the AC drive is in running state, the AC drive enters the dormant state and stops
automatically after the dormant delay time (P8-52) if the set frequency is lower than or
equal to the dormant frequency (P8-51).
When the AC drive is in dormant state and the current running command is effective, the
AC drives starts up after the wakeup delay time (P8-50) if the set frequency is higher than
or equal to the wakeup frequency (P8-49).
Generally, set the wakeup frequency 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 11-28. In this case, select
PID operation enabled in the stop state (11-28 = 1).

Current running time
reached
P8-53
If the current running time reaches the value set in this parameter, the corresponding DO
becomes ON, indicating that the current running time is reached.
