Selects the function for the digital inputs. Refer to the flowchart on page 1-24 for more information on
speed reference control priority.
Options 0 “Not Used” Terminal has no function but can be read over network
communications via d302
[Contrl In Status].
1 “Purge”
(1)
(T051 Default) Starts the drive at Purge speed regardless of the
selected start source. Purge can occur, and is
operational, at any time whether the drive is running or
stopped. If a valid stop condition is present, other than
from the Comm Port or SW Enable input (I/O Terminal
03), the drive will not start on the Purge Input Transition.
2 “Auto Mode”
(1)
When active, forces drive into “Auto” control mode. Start
source determined by P036 [Start Source] and speed
reference determined by P038
[Speed Reference].
3 “Local”
(1)
(T052 Default) When active, sets integral keypad as start source and
digital speed keys on the integral keypad as speed
source.
4 “Comm Port”
(1)
(T054 Default)
When active, sets communication device as default start/
speed command source.
5 “PID Disable” Disables PID function. Drive uses the next valid non-PID
speed reference.
6 “PID Hold” Drive output remains at current value.The integrator for
Process PID loop is also clamped at current value.
7 “PID Reset” The integrator for the Process PID loop is reset to zero
and drive output is set to Preload value.
8 “Preset Freq” Preset speed inputs that enable the use of preset
speeds.
9 “Aux Fault” If input is enable but not active, the drive will immediately
fault.
10 “Clear Fault” (T053 Default) Clears an active fault.
11 “RampStop,CF” The drive immediately ramps to stop. Can also be used
to clear a fault.
12 “CoastStop,CF” The drive immediately coasts to stop. Can also be used
to clear a fault.
13 “DCInjStop,CF” The drive immediately begins a DC Injection stop. Can
also be used to clear a fault.
Stop drive before changing this parameter.
!
ATTENTION: A Purge command will take precedence over a stop
command from the Comm Port/Network and over a SW Enable command
from the terminal block. Insure that another stop method is available, such
as I/O Terminal 01 of the control terminal block, if stopping is necessary
during a purge.
