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.
Output frequency range 0.2 to 400Hz (starting frequency variable between 0 and 60Hz)
Frequency
setting
resolution
Digital input 0.01Hz (less than 100Hz), 0.1Hz (100Hz or more)
Frequency
accuracy
Digital input Within 0.01% of set output frequency.
Voltage/frequency
characteristic
Base frequency set as required between 0 and 400Hz. Constant torque
or variable torque pattern can be selected.
Starting torque
150% or more (at 1Hz), 200% or more (at 3Hz) when general-purpose
magnetic flux vector control or slip compensation is 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
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.
Fast-response current limit

Operation level is fixed, presence or absence can be selected.
Frequency
setting signal
Digital
input
Entered through DeviceNet
TM
communication or from the parameter
unit.
Start signal Forward rotation and reverse rotation.
Possible by
DeviceNet or
parameter unit
Alarm reset
Used to reset alarm output provided when protective
function is activated.
Possible by
DeviceNet,
parameter unit
or (Pr. 192)
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 parameter unit (FR-
PU04).)
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).
External thermal relay
input
Thermal relay contact input for use when the inverter is
stopped by the external thermal relay.
Control specifications
Input signals
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.
Possible with
DeviceNet or
input terminal.
