2.2 A: Initialization Parameters
150 YASKAWA TOEPYAIGA5002A GA500 DRIVE PROGRAMMING
Note:
• Before you set A1-06, make sure that you set A1-03 = 2220, 3330 [Initialize Parameters = 2-Wire Initialization, 3-Wire Initialization] to
initialize parameters.
• It is not possible to change the A1-06 value. To set an application preset, set A1-03 = 2220 to initialize parameters, then set this parameter.
If initializing all parameters will cause a problem, do not change the settings.
If you set A2-33 = 1 [User Parameter Auto Selection = Enabled: Auto Save Recent Parms] to set parameters to A2-17 to A2-32 [User
Parameters 17 to 32] automatically, the drive will reset these parameters when you change the A1-06 setting.
