T1: Induction Motor 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)
