Setting 0: Disable
Setting 1: Enable and Declare Fault
Setting 2: Enable and Alarm Only
n Z1-32: Loss of Load Drive Frequency
Sets the value to which the drive output frequency must be equal to or greater than for the drive to detect a loss of load.
No.
Z1-32
<1> Values are given in Hz, but actual values are dependent upon unit settings using drive parameters o1-03, o1-09, o1-10, and o1-11.
n Z1-33: Loss of Load Drive Output Current
Sets the value to which the drive output current must be equal to or less than for the drive to detect a loss of load.
No.
Z1-33
n Z1-34: Loss of Load Drive Time
While in Drive mode, the Loss of Load detection conditions must be met for the length of time entered here before detecting
a loss of load.
No.
Z1-34
n Z1-35: Loss of Load Bypass Output Current
The motor current must be equal to or less than this value to detect a loss of load.
