be controlled through communication network (address 43420).

If parameter 42419 (Enables Control through communication network) is
“0”, the drive only can
be controlled through digital inputs or in not protected manual mode from the display.
If there is any digital input configured with option 75 (ALTERNATIVE MACRO CTRL), and it is closed:
 If parameter 42419 (Enables Control through communication network) is “1”, the drive only can
be controlled through communication network (address 43420).
 If parameter 42419 (Enables Control through communication network) is “0”, the drive cannot
be started or stopped until the digital input is opened or the control through communication
network is enabled.
If there is any digital input configured with option 75 (ALTERNATIVE MACRO CTRL), and it is
