Inertia ID Error
The inertia found by the drive was too
small or too large during Inertia Tuning
(10% or less, or 50000% or more).
•
Decrease the values set for the frequency and
amplitude of the test signals used when doing
inertia tuning. First, decrease the test signal
amplitude, and then do Inertia Tuning. If the
error continues, decrease the test signal
frequency and do Inertia Tuning again
•
Correctly set the motor inertia as specified by
the motor, and do Inertia Tuning again.
Er-17
Reverse Prohibited Error
b1-04 = 1 [Reverse Operation Selection
= Reverse disabled]
has been set.
Note:
You cannot do Inertia Tuning if the
drive cannot rotate the motor in
reverse.
1. Enable reverse in the target machine.
2. Set
b1-04 = 0 [Reverse enabled]
.
3. Do Inertia Tuning again.
