TECO –Westinghouse Motor Company Function Explanation 55
Monitor data (e.g.,output frequency, output current) can
be output to terminal FMP as pulse voltage. Monitor
data can also be sent to an analog meter as average
voltage.
When sending data to a digital counter or other instrument
as pulse output, set the pulse rate in F33 to any value and
the voltage in F34 to 0%.
When data is sent to an analog meter or other instrument
as average voltage, the voltage value set in F34
determines the average voltage and the pulse rate in F33
is fixed to 2670 (p/s).
This function sets the pulse frequency of the monitor
item selected in F35 within a range of 300 to 6000 (p/s)
in 1 p/s steps.
Setting range: 300 to 6,000 p/s
Pulse frequency (p/s) = 1/T
Duty (%) = T1/T x 100
Average voltage (V) = 15.6 x T1/T
The output terminal of the FMP terminal is composed of
the transistor, therefore there is a saturation voltage
(0.5V
MAX
). When using in the analogue by the filter
processing the pulse voltage, it should be make a 0V
adjustment by external equipment.
This function sets the average voltage of pulse output to
terminal FMP.
Setting range
0%: The pulse rate varies depending on the
monitor amount of the monitor item
selected in F35. (The maximum value is
the value set in F33. The pulse duty is fixed
at 50%.)
1 to 200%: Pulse rate is fixed at 2,670 p/s. The
average voltage of the monitor item
selected in F35 when the monitor amount is
100% is adjusted in the 1 to 200% range
(1% steps).
(The pulse duty varies.)
This function selects the monitor item to be output to
terminal FMP.
The set value and monitor items are the same as those
of F31.
This function specifies whether to activate (excite) the
alarm output relay (30Ry) for any fault at normal or
alarm status.

When the set value is 1, contacts 30A and 30C are
connected when the inverter control voltage is
established (about one second after power on).
When the power is off, contacts 30A and 30C are OFF;
30B and 30C are ON.

The torque limit operation calculates motor torque from
the output voltage, current and the primary resistance
value of the motor, and controls the frequency so the
calculated value does not exceed the limit. This
operation enables the inverter to continue operation
under the limit even if a sudden change in load torque
occurs.
Select limit values for the driving torque and braking
torque.
When this function is activated, acceleration and
deceleration operation times are longer than the set
values.
The motor tuning (P04 / A13) should be set to "2" for
this function is valid.
The increase frequency upper bound during torque limit
operation is set by function code : U01.
When the setting value is selected "0" (prevent OU trip),
the operation mode is selected by function code : U60.
The details are referred to the functions: U01, U60.
