Note: 1. Rotational Auto-Tuning T1-01=0 (recomm ended method)
• Rotational Auto-Tuning provides more accurate tuning results compared to Non-Rotating Auto-Tuning.
• Perform Rotational Auto-Tuning when the m otor can be uncoupled from the elevator mechanical system (remove ropes from
traction sheave).
• M ake sure to release the mechanical brake (if installed) for Rotational A uto-Tuning methods.
Stationary A uto-Tuning T1-01=1,2,or 4 (alternate method)
• Perform Stationary Auto-Tuning when the motor and mechanical system cannot be uncoupled.
• M ake sure that the mechanical brake rem ains applied for all Stationary A uto-Tuning methods.
2. W hen using a m otor contactor, make sure it rem ains closed during the A uto-Tuning process.
3. Ensure H1 and H2 signals are ON when performing Auto-Tuning.
4. A digital input programmed for B aseblock (Н 1-СЮ = 8/9) must be set so that the drive is not in a baseblock condition during A uto
Tuning.
5. Ensure the m otor is securely m ounted and bolted in place prior to Auto-Tuning.
6. To cancel Auto-Tuning, press the STOP key on the digital operator.
7. M ake sure m otor nam eplate data is readily available before A uto-Tuning the drive. A uto-Tuning requires the user to input data from
the motor nameplate or m otor test report.
8. W hen performing Auto-Tuning for m otor 2, make sure m otor 2 is connected to the drive output terminals.
9. For best performance, the drive input pow er supply voltage should be greater than the m otor rated voltage.
10. Im proved performance is possible w hen using a m otor w ith a base voltage that is 10% less than the input supply voltage. This is
particularly im portant w hen operating the m otor above 90% o f base speed, where high torque precision is required.
