Param eters A uto-T uning
T2-01 = 3
• Should be performed after motor Auto-Tuning in order to determine the PG encoder tuning method.
• Attempts to detect the motor rotor position, determines whether PG encoder offset can be tuned using Stationary Encoder Offset
Tuning and sets parameters needed for Initial Magnet Pole Search (n8-36, n8-37).
• W hen using the R escue Operation mode, perform this tuning to let the drive automatically set the parameters needed for Initial
Magnet Pole Search with power supply from a battery or UPS (n8-81, n8-82).
• Must be performed when using an incremental PG encoder.
Im portant: If this tuning fails when using a PG-X3 card with an incremental PG encoder the motor cannot be driven using an incre
mental PG encoder. Change the PG encoder to an absolute PG encoder.

A uto-T uning
T2-01 = 4
• Tunes the PG encoder offset without rotating the motor.
• If the PG encoder offset cannot be tuned properly by this method, try Rotating PG Encoder Offset Tuning.
R otation al P G E ncoder O ffset
A uto-T uning
T2-01 = 10
• Tunes the PG encoder offset w hile rotating the motor.
• Motor and m echanical system must be uncoupled (ropes must be removed from traction sheave).
