Reset interval (H05)
H05 specifies the reset interval time from when the inverter enters the tripped state until it
issues the reset command to attempt to auto-reset the state. Refer to the timing scheme
diagrams below.
<Operation timing schemes>
- In the figure below, normal operation restarts by the 4th retry.
- In the figure below, the inverter fails to restart normal operation within the number of reset
times specified by H04 (in this case, 3 times (H04 = 3)), and issues the alarm output (for
any alarm) ALM.
The auto-reset operation can be monitored from the external equipment by assigning the
digital output signal TRY to any of the programmable output terminals [Y1] and [30A/B/C]
with E20 or E27 (data = 26).
H06 Cooling Fan ON/OFF Control
To prolong the service life of the cooling fan and reduce fan noise during running, the cooling
fan stops when the temperature inside the inverter drops below a certain level while the
inverter stops. However, since frequent switching of the cooling fan shortens its service life,
the cooling fan is kept running for 10 minutes once it is started.
H06 specifies whether to keep running the cooling fan all the time or to control its ON/OFF.
Data for H06 Cooling fan ON/OFF
0 Disable (Cooling fan always ON)
1 Enable (ON/OFF control effective)
