T1: InductionMotor Auto-Tuning

T1 parameters set the Auto-Tuning input data for induction motor tuning.
Note:
• The base frequency of drive dedicated motors and special motors for use with vector control may be lower than the base frequency of
general-purpose motors, which is 50 Hz or 60 Hz. In such cases, this lower frequency is used as the value for E1-06 [Base Frequency]
and E1-04 [Maximum Output Frequency] after Auto-Tuning completes. If the maximum output frequency is too low and causes
problems, change the setting of E1-04 after Auto-Tuning completes.
• The following induction motor parameters are set automatically.
–E1-xx [V/f Pattern for Motor 1]
–E2-xx [Motor Parameters]
–E3-xx [V/f Pattern for Motor 2]
–E4-xx [Motor 2 Parameters]
–F1-xx [Encoder Options] (only with Closed Loop Vector Control)

Selection
(0700)
Note:
This parameter can be set when H1-xx = 16 [Motor 2 Selection] is ON and is not displayed when H1-xx = 16 is OFF. Motors cannot be
switched via external input. Use the keypad to display T1-00 and change the setting value to switch the motor.
1 : Motor 1 (sets E1-xx, E2-xx)
Auto-Tuning automatically sets parameters E1-xx and E2-xx for motor 1.
2 : Motor 2 (sets E3-xx, E4-xx)
Auto-Tuning automatically sets parameters E3-xx and E4-xx for motor 2. Make sure that motor 2 is connected to
the drive for Auto-Tuning.
