■ n: Advanced Performance Set-Up
The n parameters are used to adjust more advanced performance characteristics such as speed feedback detection, Online
Tuning for motor line-to-line resistance, and PM motor control tuning.
n1: Hunting Prevention
n2: Speed Feedback Detection Control (AFR) Tuning
L8-62
(529H)
Operation Selection at Input
Phase Loss
Sets stopping method when a Input phase loss fault (PF) occurs. See parameter
L8-05.
0: Ramp to Stop - Decelerate to stop using the deceleration ramp in C1-02.
1: Coast to Stop
2: Fast Stop - Decelerate to stop using the deceleration ramp in C1-09.
3: Alarm only - Drive continues operation.
Default: 1
Min: 0
Max: 3
L8-77
(61EH)
Oscillation Suppression
Used to suppress speed oscillations that occur with an unloaded motor and that
have the same frequency as the output frequency.
Default: 0
Min: -100
Max: 100
L8-88
(2F5H)
Safe Disable Operation Mode 0: Mode 0
1: Mode 1
Default: 1

1: Enabled
Default: 0
Min: 0
Max: 1
L8-99
(B98H)
Current Monitoring Level
Sets the current monitoring level as a percentage of the drive's rated current. Sets
the level of current used to monitor the status of the current (H2-
. = 5C)
when the Current Monitoring Selection (L8-89) is enabled and set to 1.
Default: 10.0 %
Min: 0.0 %
Max: 50.0 %
<1> Default setting is determined by the drive model (o2-04).
<3> Setting 3 available in V/f and OLV control only.
<4> Parameter setting value is not reset to the default value when the drive is initialized.
