Drive Setup & Programming
3 Drive Setup and Programming
Most drive parameters (including those required for serial communications) are not accessible through the
N2 Network. They can only be accessed by entering the Programming Mode of the drive itself. Refer to the
MCH Installation and Operation Manual (MH01) for more information.
When in Programming Mode, the drive will not accept any write, memorize or characterize commands from
the N2 Network. This is necessary to prevent conflicts between the two modes of parameter modification.
3.1 Serial Communication Setup
The factory default values for all drive parameters are setup to allow immediate serial communications
(without serial start and serial speed/setpoint commands). For serial speed/setpoint and/or serial start
control, modify the setting of Drive Parameter #30 (Control). The drive parameters that are required for
serial communications, including Drive Parameter #30, are described below.
30 CONTROL This parameter should be set to accommodate the specific application intent:
NORMAL Serial start and serial speed/setpoint commands are invalid.
Therefore Points 3-03, 3-04 and 3-05 are forced to act as
monitor points only and Point 4-01 can only be commanded
to 0 (STOP).
NORM NO HAND Same as NORMAL except the HAND/OFF/AUTO, herein
referred to as H/O/A, is limited to settings of OFF and AUTO.
SERIAL SPEED Serial start commands are invalid. Point 4-01 can only be
commanded to 0 (STOP). Points 3-03, 3-04 and 3-05, the
serial speed/setpoint commands, are valid in AUTO H/O/A
only.
S SPD/NO HAND Same as SERIAL SPEED except H/O/A is limited to settings of
OFF and AUTO.
SERIAL AUTO This setting forces the drive to be started over the N2 Network
when in AUTO H/O/A. Serial start and serial speed/setpoint
commands are all valid in AUTO H/O/A.
S AUTO/NO HND Same as SERIAL AUTO except H/O/A is limited to settings of
OFF and AUTO. Serial STOP commands are accepted from the
N2 Network regardless of this parameter setting.
57 SERIAL This parameter must be set to either WITH TIMER (default) or W/O TIMER for the
drive to communicate with the N2 Network. Serial communications will not work
if this parameter is set to DISABLED.
58 SERIAL ADDRESS This parameter contains the address of the N2 Network device. It is adjustable
from 1−255.
