Ambient Temperature
Setting
Ambient Temp
When the Drive is installed in an ambient temperature exceeding its
rating, Drive overload (OL2) protection level is reduced.

OL2 Characteristic
Selection at Low Speeds
OL2 Sel @ L-Spd
This parameter assists in protecting the output transistor junctions from
overheating when output current is high and output frequency is low.

Selection
Hunt Prev Select
0: Disabled (Hunting prevention function disabled.)
1: Enabled (Hunting prevention function enabled.)
If the motor vibrates while lightly loaded, hunting
prevention may reduce the vibration. There is a loss of responsiveness
if hunting prevention is enabled.

Hunting Prevention Gain
Setting
Hunt Prev Gain
Gain setting for the Hunting Prevention Function.
If the motor vibrates while lightly loaded and n1-01=1, increase the
gain by 0.1 until vibration ceases. If the motor stalls while n1-01=1
decrease the gain by 0.1 until the stalling ceases.

High-Slip Braking
Deceleration Frequency
Width
HSB Decel Width 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.

n3-02 0589H
High-Slip Braking
Current Limit
HSB Current Ref
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.

High-Slip Braking Dwell
Time at Stop
HSB DwelTim@ Stp
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.

High-Slip Braking
Overload Time
HSB OL Time
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.
