When you use an LED keypad to do Control Tuning, set the tuning mode in this order:
1. Set T0-00 = 1.
2. Set T3-00 [Control Loop Tuning Selection] to set the tuning mode.
Note:
The available tuning modes are different for different control methods.
0 : Motor Parameter Tuning
1 : Control Tuning
◆ 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]
