Carrier Frequency Reduction
Time
Sets the time for that the drive continues running with reduced
carrier frequency after the carrier reduction condition has gone
(see also L8-38).
A setting of 0.00 s disables the carrier frequency reduction
time.

STo Fault Detection Level
Sets the STo detection level as a percentage of the motor rated
current.
Increase this value to detect pull-out more quickly during
acceleration. The drive calculates this value automatically

<1> Setting 6 available in drive software versions PRG: 1016 and later.
<2> Default setting value is dependent on parameter A1-02, Control Method Selection. The value shown is for A1-02 = 0-V/f Control.
<3> Default setting value is dependent on parameter o2-04, Drive Model Selection.
<4> Default setting value is dependent on parameter o2-04, Drive Model Selection and C6-01, Drive Duty Selection.
<5> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.
<6> Default setting value is dependent on parameter E1-01, Input Voltage Setting.
<7> Setting value 2 is not available A1-02 = 5-PM OLV Control. When enabled, the drive stops accelerating when it exceeds the value of L3-02, Stall
Prevention Level. The drive decelerates after 100 ms and begins accelerating again after restoring the current level.
<8> Default setting value is 120% when C6-01 is set to 1 (ND) and 150% when C6-01 is set to 0 (HD).
<9> The setting range depends on the control mode set in A1-02. For PM OLV Control the setting range is 0 to 2 and 7.
<10> Default setting value is dependent on parameter E5-01, Motor Code Selection.
<11> Parameter value is changed if E2-11 is manually changed or changed by Auto-Tuning.
<12> Available in drive software versions PRG: 1016 and later.
<13> Parameter setting value is not reset to the default value during drive initialization, A1-03 = 1110, 2220, 3330.
<14> Available in drive software versions PRG: 1018 and later. There is normally no need to change this parameter from the default value.
<15> Default setting is determined by drive software version and C6-02 setting. Drive software versions PRG: 1021 and later have a default setting of 0
when the carrier frequency is set for Leakage Current Rejection PWM (C6-02 = B), and 1 when C6-02 is set to any other value.
<16> Parameter can be changed during Run.
<17> Available in drive software versions PRG: 1021 and later.
<18> The default setting and the upper limit of the setting range are determined by C6-01, Drive Duty Mode, and L8-38, Carrier Frequency Reduction
Selection.
