Note:
Set L3-01 = 3 [Stall Prevent Limit during Accel = ILim Mode] to enable this function.
■ L3-39: Current Limit Filter Time @Accel
No.
(Hex.)
Name Description
Default
(Range)
L3-39
(11D3)
Current Limit Filter
Time @Accel
Sets the time constant to adjust the acceleration rate when L3-01 = 3 [Stall
Prevention during Accel = Current Limit Method]. Usually it is not
necessary to change this setting.
100.0 ms
(1.0 - 1000.0 ms)
Note:
Set L3-01 = 3 [Stall Prevention during Accel = Current Limit Method] to enable this function.
■ L3-40: Current Limit S-Curve @ Acc/Dec
No.
(Hex.)
Name Description
Default
(Range)
L3-40
(11D4)
Current Limit S-
Curve @ Acc/Dec
Sets the function to enable and disable the best S-curve characteristic used
for current-limited acceleration.
0
(0, 1)
Makes the best motor acceleration rate for start up. If you set this parameter to 1, it will make acceleration more
stable, but it can also increase the acceleration time to be longer than the set time. If the drive detects oC
[Overcurrent] faults immediately after acceleration starts, set this parameter.
0 : Disabled
1 : Enabled
Note:
Set L3-01 = 3 [Stall Prevention during Accel = Current Limit Method] to enable this function.
◆ L4: Speed Detection
L4 parameters set the output of signals to the MFDO terminals, for example frequency agree and speed detection.
The drive detects motor speed in CLVor CLV/PM control methods.
■ L4-01: Speed Agree Detection Level
No.
(Hex.)
Name Description
Default
(Range)
L4-01
(0499)
Speed Agree
Detection Level
Sets the level to detect speed agree or motor speed.
Determined by A1-02
(Determined by A1-
02)
Sets the level to detect speed agree or motor speed when H2-01 to H2-03 = 2, 3, 4, 5 [MFDO Function Select =
Speed Agree 1, User-set Speed Agree 1, Frequency Detection 1, Frequency Detection 2].
■ L4-02: Speed Agree Detection Width
No.
(Hex.)
Name Description
Default
(Range)
L4-02
(049A)
Speed Agree
Detection Width
Sets the width to detect speed agree or motor speed.
Determined by A1-02
(Determined by A1-
02)
Sets the width to detect speed agree or motor speed when H2-01 to H2-03 = 2, 3, 4, 5 [MFDO Function Select =
Speed Agree 1, User-set Speed Agree 1, Frequency Detection 1, Frequency Detection 2].
