n3 High-Slip Braking
◆ n3-01 High-Slip Braking Deceleration Frequency
Setting Range: 1.0 ~ 20.0%
Factory Defaults: 5%
Sets how aggressively the drive decreases the output frequency as it stops the motor. If overvoltage (OV) faults occur during HSB, this
parameter may need to be increased.
Note: Function Deactivated
◆ n3-02 High-Slip Braking Current Limit
Setting Range: 100.0 ~ 200.0%
Factory Defaults: 150%
Sets the maximum current to be drawn during a HSB stop. Higher n3-02 settings will shorten motor stopping times but cause increased
motor current and therefore, increased motor heating.
Note: Function Deactivated
◆ n3-03 High-Slip Braking Dwell Time at Stop
Setting Range: 0.00 ~ 10.00 s
Factory Defaults: 1.0 s
Sets the amount of time the drive will dwell at E1-09 (Minimum Frequency). If this time is set too low, the machine inertia can cause the
motor to rotate slightly after the HSB stop is complete and drive output is shut off.
Note: Function Deactivated
◆ n3-04 High-Slip Braking Overload Time
Setting Range: 30.0 ~ 1200.0 s
Factory Defaults: 40 s
Sets the time required for a HSB Overload Fault to occur when the drive output frequency does not change for some reason during a HSB
stop. Normally this does not need to be adjusted.
Note: Function Deactivated
