F33 FMP terminal (pulse rate)
F34 FMP terminal (voltage adjustment)
F35 FMP terminal (function selection)
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 instru-
ment 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 instru-
ment as average voltage, the voltage value set in F34
determines the average voltage, and F33 is fixed at 2670
(p/s).
F 3 3 F M P P L U S E S
Set values: 300 to 6,000 p/s, in 1 p/s increments
The F33 function sets the pulse frequency of the monitor
item selected in F35.
Pulse frequency (p/s) = 1/T
Duty (%) = T1/T x 100
Average voltage (V) = 15.6 x T1/T
F 3 4 F M P V – A D J
Set value 0%: The pulse frequency varies depending on
the amount of the monitor item selected in F35 (max.
value is the value set in F33).
The F34 function sets the average voltage of pulse
output to terminal FMP.
1 to 200%: Pulse frequency 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
range 1 - 200%, in 1% increments (pulse duty varies).
F 3 5 F M P F U N C
The F35 function selects the monitor item to be output to
terminal FMP.
The set value and monitor items are the same as those
used for F31 (refer to table).
F36 30Ry operation mode
F 3 6 3 0 R Y M O D E
This function specifies whether to activate (excite) the
alarm output relay (30Ry) for any fault at normal or alarm
status.
Value
0 Drive no power 30A - 30C: OFF, 30B - 30C: ON
At normal 30A - 30C: OFF, 30B - 30C: ON
At alarm 30A - 30C: ON, 30B - 30C:OFF
1 Drive no power 30A - 30C: OFF, 30B - 30C: ON
At normal 30A - 30C: ON, 30B - 30C: OFF
At alarm 30A - 30C: OFF, 30B - 30C: ON
Operation
If the set value is 1, contacts 30A and 30C are connected
when the drive control voltage is established (about one
second after power on).
F40 Torque limit 1 (drive)
F41 Torque limit 1 (brake)
F 4 0 D R V T R Q I
F 4 1 B R K T R Q I
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 opera-
tion enables the drive to continue operation under the
limit even if a sudden change in load torque occurs.
Limits are set for driving torque and braking torque.
When this function is activated, acceleration and
deceleration operation times are longer than the set
values.
Function Set Value Operation
Torque 20% to 200% The torque is limited
limit to the set value.
(driving)
999 Torque limiting inactive
Torque 20% to 200% The torque is limited to
limit the set value.
(braking)
0 Automatically prevents
OU trip due to power
regeneration effect
999 Torque limiting inactive
WARNING
When the torque limit function is selected, an
operation may not match the set acceleration and
deceleration time or set speed. The machine should
be so designed that safety is ensured even when
operation does not match the set values.
