MODIFIED CONSTANTS MODE
Compares the constant values preset at the factory with the values changed by the user, and displays
the constants changed from the preset constants automatically. In the modified constants mode,
constants can be read; in addition, they can also be set or changed.
( Example )
Read the constants C1
− 01 (accel time 1) and E1 − 01 (input voltage) when the factory settings
have been changed. In addition, change the setting of E1 − 01 (input voltage) from 575V to
600V in this mode.
