Figure 26 - Wiring Example
Drive Configuration Both of the digital inputs required to monitor for motor over temperature must
be configured correctly to assure that the drive will shut down independent of
drive software operation, and be put into a fault condition that will require a fault
reset before the drive can be restarted.
Hardware
Digital Input 6 must be configured as a Hardware Enable. This is accomplished
by removing Jumper J10 from the Main Control Board in the I/O Control
Cassette. Refer to the instructions in the I/O wiring section of the Installation
Instructions.
Firmware
• The functionality of Digital Input 5 is determined by parameter 365
[Digital In5 Sel]. (If a different digital input “x” is selected, refer to the
corresponding [Digital In “x” Sel] parameter.) This parameter must be set
to a value of “3” to configure this input as an “Aux Fault.” When this digital
input is opened, the drive will immediately shut down in a fault condition
and require a fault reset before the drive can be restarted.
• Opening Digital Input 6 when configured as a Hardware Enable will
interrupt IGBT gate firing directly. Additionally, Digital Input 6 will put
the drive into a normal “not-enabled” shutdown condition. It is configured
by parameter 366 [Digital In6 Sel]. This parameter must be set to a value
of “1” to configure this input as an “Enable.” When Digital Input 6 is
opened, the gate firing will be interrupted and the drive will go into a “not-
enabled” shutdown condition. Because the additional digital Input
(typically Digital Input 5) must be wired to open simultaneously and be
configured to put the drive into a fault condition, the drive will not restart
if a new start command is given until the fault is reset.
