Table 27 Types of Auto-Tuning for PG Encoder Offset
Setting
• 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).
• When using the Rescue Operation mode, perform this tuning to let the drive automatically set the
T2-01 = 3
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.
Important: If this tuning fails when using a PG-X3 card with an incremental PG encoder the motor
cannot be driven using an incremental PG encoder. Change the PG encoder to an absolute PG encoder.
• Tunes the PG encoder offset without rotating the motor.
T2-01 = 4
• If the PG encoder offset cannot be tuned properly by this method, try Rotating PG Encoder Offset
Tuning.
• Tunes the PG encoder offset while rotating the motor.
T2-01 = 10
• Motor and mechanical system must be uncoupled (ropes must be removed from traction sheave).
