YASKAWA P1000 Technical Manual

• When using the drive in common DC bus applications and the internal braking unit is not installed.
Enabling L8-55 under such conditions can incorrectly trigger a braking resistor fault (rF).
Setting 1: Enabled
Enable L8-55 when connecting a braking resistor or a braking resistor unit to the drive built-in braking transistor.
Models 2A0004 to 2A0138, 4A0002 to 4A0072, and 5A0003 to 5A0052 come with a built-in braking transistor.

n
L8-94: LSo Detection Level at Low Speed
Determines the detection level of STo at low speed. Set as a percentage of the maximum frequency (E1-04).
No. Name Setting Range Default
L8-94 LSo Detection Level at Low Speed 0 to 10% 3%
n
L8-95: Average LSo Frequency at Low Speed
Sets the average number of times LSo can occur at low speed.
No. Name Setting Range Default
