Switch Description
S100 Modbus link termination and biasing
(TERM voltages to the bus.
& BIAS) Set to ON position when the drive is the
last unit on the link.
S100 Modbus link termination. Must be set to
(TERM) the terminated (ON) position when the
drive is the first or last unit on the link.
S200 Switches on the biasing voltages to the
(BIAS) bus. One (and only one) device, prefer-
ably at the end of the bus must have the
bias on.
