L&T VFD Sx series Multi Keypad Function

Use multi-keypad settings to control more than one inverter with one keypad. To use this function, first configure RS-485 communication.
The group of inverters to be controlled by the keypad will include a master inverter. The master inverter monitors the other inverters, and slave inverter responds to the master inverter’s input. When using multi-function output, a slave inverter can select to use either the master inverter’s output or its
own output. When using the multi keypad, first designate the slave inverter and then the master inverter. If the master inverter is designated first, connected inverters may interpret the condition as a loss of communication.
