TECO –Westinghouse Motor Company Function Explanation 73
This function returns all function data changed by the
customer to the factory setting data. (initialization).
Set value 0： Disabled.
1： Initializing data.
To perform initialization, press the and keys
together to set 1, then press the key. The set
values of all functions are initialized. The set value in
H03 automatically returns to 0 following the end of
initialization.
When the inverter protective function which invokes the
retry operation is activated, this function releases
operation of the protective function and restarts
operation without issuing an alarm or terminating output.
Set the protective function release count and waiting
time from its operation startup to release.
Setting range (Count) : 0, 1 to 10
(Waiting time) : 2 to 20 seconds
To disable the retry function, set 0 to "H04 Retry (count)."
Inverter protective functions that can invoke retry
function.
OC1,OC2,OC3
: Overcurrent dBH
: Braking resistor overheating
OV1,OV2,OV3
: Overvoltage OL1
: Motor 1 overload
OH1
: Heat sink overheating OL2
: Motor 2 overload
OH3
: Inverter inside overheating OLU
: Inverter overload
When the value of "H04 Retry (count)," is set from 1 to
10, an inverter run command is immediately entered
following the wait time set in H05, "Retry (wait time),"
and the startup of the retry operation. If the cause of
the alarm has been removed at this time, the inverter
starts without switching to alarm mode. If the cause of
the alarm still remains, the protective function is
reactivated according to the wait time set in "H05 Retry
(waiting time)." This operation is repeated until the
cause of the alarm is removed. The restart operation
switches to alarm mode when the retry count exceeds
the value set in "H04 Retry (count)."
The operation of the retry function can be monitored
from terminals Y1 to Y5.
WARNING
When the retry function is selected,
operation automatically restarts depending
on the cause of the trip stop. (The
machine should be designed to ensure
safety during a restart)
Otherwise accidents may result.

This function specifies whether cooling fan ON/OFF
control is automatic. While power is applied to the
inverter, the automatic fan control detects the
temperature of the cooling fan in the inverter and turns
the fan on or off.
When this control is not selected, the cooling fan rotates
continually.

Set value 0: ON/OFF control disabled.
1: ON/OFF control enabled.
The cooling fan operating status can be monitored from
terminals Y1 to Y5.
