■ 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
smoother, 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 : Disable
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].
■ L4-03: Speed Agree Detection Level (+/-)
No.
(Hex.)
Name Description
Default
(Range)
L4-03
(049B)
Speed Agree Detection
Level (+/-)
Sets the level to detect speed agree or motor speed.
Determined by A1-02
(Determined by A1-02)
Sets the speed agree detection level or motor speed detection level when H2-01 to H2-03 = 13, 14, 15, 16 [MFDO
Function Selection = Speed Agree 2, User-set Speed Agree 2, Frequency Detection 3, Frequency Detection 4].
