13-14 Understanding the Auto-tuning Procedure
7
Running
The drive is currently running.
8 – 11 Reserved
12
Timeout
The inertia test has run for one minute without measuring at least a 5% change in motor speed. Possible excessive load.
Try running a higher level of Autotune Torque (parameter 164).
13
No Trq Lim
The inertia test has measured a Motor Speed (parameter 81) in excess of half the Autotune Speed (parameter 165), but
a Torque Limit Sts (parameter 87) has not been indicated. The drive enters a torque limit condition at the start of the
inertia test.
• Make sure the motor is stopped or at least rotating at less than half the auto-tune speed before beginning the inertia
test.
• If the motor is not rotating at the start of the inertia test, investigate encoder and related wiring as a source for
incorrect speed feedback.
