-
Speed Search
Yes
Yes
Yes (Although NOT operation in
the reverse direction of the Run
command)
Immediately estimates (or detects) motor
speed and direction when coasting to a
stop to quickly start-up the drive without
stopping the motor.
Automatic Energy-
saving Control
No
Yes (IPM motors only)
Yes
Automatically adjusts the voltage that the
drive applies to the motor to maximize
motor efficiency for small and large loads.
High Slip Braking
(HSB)
No (induction motor-specific
function)
No (induction motor-specific
function)
No
Increases motor loss to let the motor
decelerate faster than usual without a
braking resistor. Motor characteristics have
an effect on this function.
Feed Forward Control
No
Yes
No
Compensates effects of the system inertia
to increase the speed precision when the
load changes.
KEB Ride-Thru
Function
Yes
Yes
Yes
Quickly and safely stops the motor during
power loss and automatically starts
operation at the previous speed when the
drive applies power again without coasting
the motor.
Overexcitation
Deceleration
No (induction motor-specific
function)
No (induction motor-specific
function)
No
Sets the V/f higher than the setting value
during deceleration to increase motor loss
and decrease deceleration time.
Overvoltage
Suppression Function
Yes
Yes
Yes
Adjusts speed during regeneration to
prevent overvoltage.
*1
Enabled when
n8-57 = 1 [High-Freq Injection = Enabled]
.
*2
Rotational Auto-Tuning is necessary.
*3
Select the drive capacity accordingly.
*4
Note these points when you use this function:
•
When you can decouple the motor and machine for a test run, use Rotational Auto-Tuning. You must make adjustments to the
control in the range where there is no vibration in the machine after Rotational Auto-Tuning.
•
For vector control, use a 1:1 drive to motor ratio. You cannot use vector control when more than one motor is connected to one
drive. Select a drive capacity so that the motor rated current is 50% to 100% of the drive rated current. If the carrier frequency is
too high, the drive rated current is derated.
*5
Do not use this function with hoist application.
