■
L3-40: Current Limit S-Curve @ Acc/Dec
No.
Name
(Hex.)
L3-40 Current Limit S-Curve @
Acc/Dec
(11D4)
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 : No
1 : Yes
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 CLV or CLV/PM control methods.

L4-01: Speed Agree Detection Level
No.
Name
(Hex.)
L4-01 Speed Agree Detection
Level
(0499)
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.
Name
(Hex.)
L4-02 Speed Agree Detection
Width
(049A)
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.
Name
(Hex.)
L4-03 Speed Agree Detection
Level (+/-)
(049B)
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].
■
L4-04: Speed Agree Detection Width (+/-)
No.
Name
(Hex.)
L4-04 Speed Agree Detection
Width (+/-)
(049C)
Sets the width to detect speed agree or motor speed 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].
