9: Drive Enable / Drive Disable - For use with external control logic, all Drive Enable in-
puts must be on, and all Drive Disable inputs off, for the drive to run. If a Drive Enable in-
put is removed while the motor is running, the motor will coast to a stop.
10: Input Phase Fault - For use with an external incoming line voltage protection relay, if
this input goes high, the drive will fault.
11: Transformer Fault - For use with protection switches on a remotely located front end
transformer, such as applications monitoring pressure or level switches of an oil-filled
transformer. If this input goes low, the drive will fault.
12: Transformer Warning -Also for use with protection switches on a remotely located
front end transformer. If this input goes low, the drive will indicate a warning.
13: Converter Warning - For use with protection switches in the Convertor or rectifier sec-
tion. If this input goes low, the drive will indicate a warning.
14: Converter Fault - Also for use with protection switches in the Converter or rectifier
section. If this input goes low, the drive will fault.
15: Main Contactor Feedback - For internal control logic only. The drive uses this input to
monitor the main contactor in the Inverter section.
16:
Output Contactor Feedback - When there is an output contactor controlled by the
drive with a digital output programmed as “Output Contactor Control”, a digital input
should be programmed to monitor feedback from its normally open auxiliary contact.
17:
Input Disconnect Feeback – When there is an input disconnect switch, a digital input
should be programmed to monitor feedback from its normally open auxiliary contact.
18:
Output Disconnect Feedback – When there is an output disconnect switch, a digital
input should be programmed to monitor feedback from its normally open auxiliary con-
tact.
19:
DC Link Rector Warning – When there is a DC link reactor, a digital input should be
programmed to monitor its normally closed temperature warning switch.
20:
DC Link Ractor Fault – When there is a DC link reactor, a digital input should be pro-
grammed to monitor its normally close temperature trip switch.
21:
Output Reactor Warning – When there is an output reactor, a digital input should be
programmed to monitor its normally closed temperature warning switch.
22:
Output Reactor Fault – When there is an output reactor, a digital input should be pro-
grammed to monitor its normally closed temperature trip switch.
