(1) Contacts shown in unpowered state. Any relay programmed as Fault or Alarm will energize (pick
up) when power is applied to drive and deenergize (drop out) when fault or alarm exists. Relays
selected for other functions will energize only when that condition exists and will deenergize when
condition is removed.
(2) These inputs/outputs are dependent on a number of parameters. See “Related Parameters.”
(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 only available with Enhanced Control drives.
