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.

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 level
Operation level is fixed, presence or absence can be selected.

setting signal
(Note 5)
Digital
input
Entered through CC-Link communication or from the parameter unit.
Start signal (Note 5) Forward and reverse rotation.
Possible by CC-Link
or parameter unit
Alarm reset (Note 6)
Used to reset alarm output provided when protective
function is activated.
Possible by CC-Link,
parameter unit or
input terminal
Multi-speed selection
(Note 6)
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 control panel.)
Second function
selection (Note 6)
Used to select second functions (acceleration time,
deceleration time, torque boost, base frequency,
electronic overcurrent protection).
Output stop (Note 6)
Instantaneous shut-off of inverter output (frequency,
voltage).
External thermal
relay input (Note 6)
Thermal relay contact input for use when the inverter
is stopped by the external thermal relay (Pr. 183).
Control specifications
Input signals
V/F-general-purpose
magnetic flux
switching (Note 6)
Used to switch between V/F control and general-
purpose magnetic flux vector control from outside
the inverter.
Possible by CC-Link
or input terminal
