Caution
Set 2nd inertia ratio.
You can set up the ratio of the load inertia against the rotor (of the motor) inertia.
Pr6.13 = (load inertia/ rotor inertia) × 100 [%]
If the inertia ratio is correctly set, the setup unit of Pr1.01 and Pr1.06 becomes (Hz). When
the inertia ratio of Pr0.04 is larger than the actual, the setup unit of the velocity loop gain
becomes larger, and when the inertia ratio of Pr0.04 is smaller than the actual, the setup unit
of the velocity loop gain becomes smaller.

P S T F
Set up the time allowed to complete emergency stop in an alarm condition. Exceeding this
time puts the system in alarm state.
When setup value is 0, immediate stop is disabled and the immediate alarm stop is enabled.

When the motor speed exceeds this setup time, Err26.1 2nd over-speed protection will be
activated.
The over-speed level becomes 1.2 times of the motor max. speed by setting up this to 0.

) after power-up.
For example, when setup value is 10, then 1.5 s + (10 × 0.1 s) = approx. 2.5 s.
