Torque Limit Delay
Time
TRQ Dly Filter T
Sets the filter time constant in seconds for the torque limit value
to
return to set value when the Power KEB Ride-Thru is enabled
(L2-29 = 1). If oscillation occurs during Power KEB Ride-
Thru, gradually increase this setting in increments of 0.010 s.
Note: This parameter is not available in models
4A0930 and 4A1200.
Default:
<9>
Min.: 0.000
Max.: 1.000

Speed Agree Width at
Intelligent Stall
Prevention during
Deceleration
IntDecSpdAgrWdth
Sets the width of the speed agree when L3-04 = 2 (Intelligent
Stall Prevention during deceleration) in units of 0.01 Hz.
There is normally no need to change this parameter from the
default value.
Note: This parameter is not available in models
4A0930 and 4A1200.
Default: 0.00 Hz
Min.: 0.00
Max.: 1.00

<1> The default setting and upper limit are determined by C6-01, Drive Duty Selection, and L8-38, Frequency Reduction Selection.
<2>
The setting range is 0 to 2 in OLV/PM control mode. The setting range is 0 and 1 in CLV or AOLV/PM control modes.
<3> Default setting is determined by parameter E1-01, Input voltage Setting.
<4> Default setting is determined by parameter A1-02, Control Method Selection.
<5> Parameter value changes automatically if E2-11 is manually changed or changed by Auto-Tuning.
<6> Default setting is determined by parameters C6-01, Drive Duty Selection, and o2-04, Drive Model Selection.
<7> Default setting is determined by parameter E5-01, Motor Code Selection.
<8> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives, but
set the value below 1040 Vdc (overvoltage protection level).
<9> Default setting is determined by parameter A1-02, Control Method Selection.
When A1-02 = 6 (AOLV/PM), default is 0.2
When A1-02 = 7 (CLV/PM), default is 0.02.
<10> Available in drive software versions PRG: 1018 and later.
