4.2.1 Keypad LED and Button Functions
Some of the keypad buttons, whose functions are described below, are dual-purpose. The dual-purpose keys have
one function when used in a view-only mode, and another function when used in a programming mode.
*1 The STOP key has highest priority. Pressing the STOP key will always cause the VFD to stop the motor, even if a Run command is active at
any external Run command source.
*2 The LO/RE key can only switch between LOCAL and REMOTE when the VFD is stopped. To enable the LO/RE key to switch between
LOCAL and REMOTE, set parameter O02-01 = 1.
