(1) Contacts shown in unpowered state. Any relay that is programmed as fault or alarm energizes (pick up) when power is applied to drive and deenergizes (drop out) when fault or alarm exists. Relays
selected for other functions energize when the condition exists, and deenergize when the condition is removed.
(2) These inputs/outputs are dependent on a number of parameters. See the Related Parameters column in Tab le 1 7
.
(3) Differential isolation - external source must be less than 10V with respect to PE.
(4) Differential isolation - external source must be maintained at less than 160V with respect to PE. Input provides high common mode immunity.
(5) Analog output current is available only with enhanced control drives.
