• In the figure below, the inverter failed to restart normal operation within the number of reset times specified by
H04 (in this case, 3 times (H04 = 3)), and issued 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], [Y2] or [30A/B/C] by setting E20, E21 or E27
respectively (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 keeps running for at least 10 minutes once
started.
H06 specifies whether to keep running the cooling fan all the time or to enable ON/OFF control.
H06 data Function
0 Disable (Always in operation)
1 Enable (ON/OFF controllable)
■
Cooling fan in operation -- FAN (E20, E21 and E27, data = 25)
With the cooling fan ON/OFF control enabled (H06 = 1), this output signal is ON when the cooling fan is in
operation, and OFF when it is stopped. This signal can be used to make the cooling system of peripheral
equipment interlocked for an ON/OFF control
H07 Curve acceleration/ deceleration (refer to F07)
For details, refer to the description of F07.
H08 Rotational direction limitation
H08 inhibits the motor from running in an unexpected rotational direction due to miss-operation of run commands,
miss-polarization of frequency commands, or other mistakes.
H08 data Function
0 Disable
1 Enable (Reverse rotation inhibited)
2 Enable (Forward rotation inhibited)
