12.9 L: Protection Functions
690 YASKAWA SIEPC71061753A GA500 Technical Manual
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.

Fref Loss Detection
Selection
Sets the operation when the drive detects a loss of frequency reference.
0
(0, 1)
Enables the detection of a loss of an analog frequency reference when MFAI terminals (A1 and A2) input the
frequency reference. Set
H2-01 to H2-03 = C [MFDO Function Selection = Frequency Reference Loss] to enable
this function.
If the frequency reference is less than 10% in 400 ms, the drive detects frequency reference loss.
