can have three sources of start and stop control; Terminal, Keypad and Serial. Two parameters, (P4
/ QST 04) - Local Source and (P5 / QST 05) - Remote Source, allows the user to change the control source.
If a digital input is programmed as “L-r” (Local / Remote), then that input selects the control source. When
the input is low, the local source is used. When the input is high, the remote source is used. If no digital input
is programmed as “L-r”, then the local/remote bit in the starter control Modbus register selects the control
source. The default value of the bit is Local (0).
