<1> Upper limit is dependent on parameter L8-38, Frequency Reduction Selection.
<2> The setting range is 0 to 2 in OLV/PM control mode.
<3> Default setting is dependent on parameter E1-01, Input voltage Setting.
<4> Values shown are specific to 200 V class drives. Double the value for 400 V class drives.
<5> Default setting is determined by parameter A1-02, Control Mode Setting.
<6> Parameter value changes automatically if E2-11 is manually changed or changed by Auto-Tuning.
<7> Default setting is dependent on parameter o2-04, Drive Model Selection.

When DC bus capacitors have been added externally, be sure
ExtDC busCapSize to add those values to the internal capacitor table for proper DC
bus calculations.

L4-01 sets the frequency detection level for digital output
Spd Agree Level functions H2-
L4-02 sets the hysteresis or allowable margin for speed
Spd Agree Width detection.
L4-03 sets the frequency detection level for digital output
Spd Agree Lvl+- functions H2-
L4-04 sets the hysteresis or allowable margin for speed
Spd Agree Wdth+- detection.
Ref Loss Sel 0: Stop. Drive stops when the frequency reference is lost.
0: Stop 1: Run. Drive runs at a reduced speed when the frequency
1: Run@L4-06PrevRef reference is lost.
Sets the percentage of the frequency reference that the drive
Fref at Floss should run with when the frequency reference is lost.
Freq Detect Sel 0: No detection during baseblock.
0: No Detection @BB 1: Detection always enabled.
1: Always Detected
