L8-18: Software CLA Selection
■
The Software Current Limit (CLA) is a drive protection function that prevents main circuit transistor failures caused by
high current. Parameter L8-18 enables or disables a drive protection function.
Note: This setting should not be changed unless absolutely necessary. For proper drive protection and operation leave the Software
CLA function enabled.
No.
L8-18
Setting 0: Software CLA disabled (gain = 0)
The drive may trip on an oC fault if the load is too heavy or the acceleration is too short.
Setting 1: Software CLA enabled
When the soft CLA current level is reached, the drive reduces the output voltage in order to reduce the current. If the
current level drops below the Software CLA level, then normal operation will continue.
L8-32: Backup Fan Use Selection
■
Sets whether the backup fan is used or not.
No.
L8-32
Setting 0: Backup fan provided
Setting 1: No backup fan
L8-33: Fan Board Use Selection
■
Sets the number of fan control boards (FFB boards) used.
No.
L8-33
<1> For details on the default settings, refer to
Setting 0: No fan boards used
Setting 1: One fan boards used
Setting 2: Two fan boards used
■ L8-63: Output Side Overvoltage Detection Level
Parameter L8-63 sets the detection level for overvoltage at the output side. Set as a percentage of the maximum motor
voltage in 0.1% units.
No.
L8-63 Output Overvoltage Detection Level
L8-64: Output Overvoltage Detection Time
■
Sets the time before an Output Overvoltage (oov) is detected, in 0.01 s units. If the state in which the output voltage
exceeds the value set for L8-63 continues for the time set for L8-64 or longer, Output Overvoltage (oov) is detected.
No.
L8-64 Output Overvoltage Detection Time
