Control system
Soft-PWM control/high carrier frequency PWM control can be
selected. V/F control or general-purpose magnetic flux vector control
can be selected.

Analog input
Across terminals 2-5: 1/500 of maximum set frequency (5VDC input),
1/1000 (10VDC, 4-20mADC input)
Digital input
0.01Hz (less than 100Hz), 0.1Hz (100Hz or more) when digital setting
is made using the operation panel

accuracy
Analog input Within ±0.5% of maximum output frequency (25
°C ±10°C (77°F ± 18°F))
Digital input
Within 0.01% of set output frequency when setting is made from
operation panel.
Voltage/frequency characteristic
Base frequency set as required between 0 and 400Hz. Constant
torque or variable torque pattern can be selected.
Torque boost Manual torque boost, 0 to 30% may be set.
Acceleration/deceleration time
setting
0.01, 0.1 to 3600 s (acceleration and deceleration can be set individually),
linear or S-pattern acceleration/deceleration mode can be selected.
Braking torque

002 ... 50%, 003, 005, 007.5, 010 ... 20%
DC injection
brake
Operation frequency (0 to 120Hz), operation time (0 to 10 s),
operation voltage (0 to 30%) variable
Current stall prevention
operation level
Operation current level can be set (0 to 200% variable), presence or
absence can be selected.
Voltage stall prevention
operation level
Operation level is fixed, presence or absence can be selected.
High-response current limit level Operation level is fixed, presence or absence can be selected.
Input signals
Frequency
setting
signal
Analog input 0 to 5VDC, 0 to 10VDC, 4 to 20mADC
Digital input Entered from operation panel (optional FR-PA02
-02).
Start signal
Forward rotation and reverse rotation, start signal self-holding input
(3-wire input) selectable.
Alarm reset
Used to reset alarm output provided when protective function is
activated.
Multi-speed selection
Up to 15 speeds can be selected. (Each speed can be
set between 0 and 400Hz, running speed can be
changed during operation from the operation panel.)
Use
Pr. 180 to
Pr. 183 for
selection.
Second function selection
Used to select second functions (acceleration time,
deceleration time, torque boost, base frequency,
electronic overcurrent protection).
Output stop
Instantaneous shut-off of inverter output (frequency,
voltage).
Current input selection
Used to select input of frequency setting signal 4 to
20mADC (terminal 4).
External thermal relay input
Thermal relay contact input for use when the inverter is
stopped by the external thermal relay.
PU operation-external
operation switchover
Used to switch between PU operation and external
operation from outside the inverter.
V/F-general-purpose
magnetic flux switching
Used to switch between V/F control and general-purpose
magnetic flux vector control from outside the inverter.
