HSB CurrLim Level
Sets the maximum current output during high-slip braking as a percentage, where
E2-01 [Mot
Rated Current (FLA)]
is 100%. Also set the current suppression to prevent exceeding drive
overload tolerance.
Determined by C6-01 and
L8-38
(0 - 150%)
Note:
The upper limit to the setting range changes when the setting for
C6-01 [Normal / Heavy Duty Selection]
changes.
•
150% when
C6-01 = 0 [HD Rating]
•
120% when
C6-01 = 1 [ND Rating]
When you decrease the setting value for current suppression, it will make the deceleration time longer.
•
When you must detect
ov [DC Bus Overvoltage]
during high-slip braking, set this parameter to a low value.
•
If the motor current increases during high-slip braking, decrease the setting value to prevent burn damage in the
motor.
•
The overload tolerance for the drive is 150% for Heavy Duty Rating (HD) and 110% for Normal Duty Rating
(ND).

HSB DwellTime@Stop
Sets the dwell time, a length of time when high-slip braking is ending and during which the motor
speed decreases and runs at a stable speed. For a set length of time, the drive will hold the actual
output frequency at the minimum output frequency set in
E1-09
.
1.0 s
(0.0 - 10.0 s)
If there is too much inertia or when the motor is coasting to a stop after high-slip braking is complete, increase the
setting value. If the setting value is too low, machine inertia can cause the motor to rotate after high-slip braking is
complete.

HSB Overload Time
Sets the time used to detect
oL7 [High Slip Braking Overload]
, which occurs when the output
frequency does not change during high-slip braking. Usually it is not necessary to change this
parameter.
40 s
(30 - 1200 s)
If a force on the load side is rotating the motor or if there is too much load inertia connected to the motor, the
drive will detect
oL7
.
The current flowing to the motor from the load can overheat the motor and cause burn damage to the motor. Set
this parameter to prevent burn damage to the motor.
■
n3-13: OverExcBr Gain
No.
(Hex.)
Name
Description
Default
(Range)
n3-13
(0531)
OverExcBr Gain
Sets the gain value that the drive multiplies by the V/f pattern output value during overexcitation
deceleration to calculate the overexcitation level.
1.10
(1.00 - 1.40)
The V/f pattern output value goes back to its usual level after the motor stops or accelerates again to the frequency
reference speed.
The best value of this parameter changes when the flux saturation characteristics of the motor change.
•
Gradually increase the value of
n3-13
to 1.25 or 1.30 to increase the braking power of Overexcitation
Deceleration. If the gain is too much, the motor can have flux saturation and cause a large quantity of current to
flow. This can increase the deceleration time.
•
Decrease the setting value if flux saturation causes overcurrent. If you increase the setting value, the drive can
detect
oC [Overcurrent]
,
oL1 [Motor Overload]
, and
oL2 [Drive Overload]
. Decrease the value of
n3-21
[OverExcBr Current Level]
to prevent
oC
and
oL
.
•
Regular use of overexcitation deceleration or extended periods of overexcitation deceleration can increase
internal motor temperatures. Decrease the setting value in these conditions.
