Rockwell Automation 1395 Digital DC Drive FRN 5-10.10/9.30 - Manual (Page 194)

Chapter 7
Programming Parameters
7-28
The drive will continue to run using the Jog 1 speed reference until
this bit is set to 0. At this time, velocity reference will be set to zero
and the drive regenerate to a stop. Once the motor has stopped,
velocity regulation will stop. The contactor will remain closed for the
time specified by Jog Dwell (Parameter 711). For jogging, the ramp
function may be using the Jog Ramp Enable (Parameter 626).
Normal Stop (Bit 11) : A 1-bit field specifying the drive to decelerate
the motor to zero velocity, and when at zero velocity, open the
contactor. The normal stop bits in both Logic Command 1,2 and 3
are active, regardless of the state of the command enable bit in Logic
Command 1 or 3. Normal Stop will override the Start function.
Important: Refer to Chapter 6 – Installation, for important
information and warnings regarding stop mode interfaces with the
1395.
Start (Bit 12) : A 1-bit field specifying the drive to close the
contactor and run the motor at the speed specified in the reference
select A, B or C in the logic command (bits 0,1,2). This bit will be
treated as a maintained signal if the Maintained Start (Parameter 624)
is set to 1. For a maintained Start, the motor will stop should this bit
be cleared. If maintained Start is not selected (Parameter 624 = 0),
this bit will be latched by the Drive and a Stop input will be required
to stop the motor.
Close Contactor (Bit 13) : A 1-bit field when set to 1, closes the
motor contactor. When set to 0, opens the contactor. On the rise of
this input, the contactor will be manually closed. The contactor will
remain closed until this bit is set to 0, or a hard fault, soft fault or
ECOAST request occurs.
Clear Fault (Bit 14) : A 1-bit field that will clear all warning and
most soft faults present in the Drive when set to 1. When set to 0, the
clear faults is inactive. Hard faults (except Communication Faults via
PLC/RIO) require system reset or cycling of control power.
Process trim enable (Bit 15): A 1-bit field that will make the Process
trim function active when set to 1. The Process Trim Reference and
Feedback (Parameters 161,162) will be used to generate the Process
Trim Output (Parameter 119). When this bit is set to 0, the Process
Trim Output is set to zero and the Process Trim Reference and
Feedback inputs are not used.
Parameter 151 – Logic Command 2 [Logic Cmd 2]
Internal units : None
Programming Terminal units: Bit Field
Description : This word controls Drive logic operation when the
Command/Enable bit in Logic Command 1 and Logic Command 3 is
low (0). The Stop request bit in Logic Command 2 is active,
regardless of the Command/Enable selection status. All other
functions present in Logic Command 2 are identical to Logic
Command 1.
