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
MC3000 Installation and Operation Manual (M301) 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 should be set to accommodate the specific application intent. The action of a
Watchdog timeout depends on the setting of the CONTROL parameter. If the
CONTROL parameter is set for:
− LOCAL : the drive will stop when a serial timeout occurs.
− KEYPAD 2 (LOCAL contol without the need for TB-1 to run): the drive will stop
when a serial timeout occurs.
− REMOTE: serial timeout will not work since the drive cannot be unlocked in
REMOTE mode.
MC3000 drives STOP when a serial timeout occurs. There is no fault for this. Any
time CONTROL is changed from LOCAL to REMOTE the drive STOPS immediately.
The Control Parameter on MC drives (Programming Parameter #30 / AC Tech Register #81) determines
how much control a user has over a drive via the serial link. The Control Parameter must be appropriately
programmed for a particular application. Refer to the MC Series Installation and Operation Manual (M301)
for a detailed explanation on programming the drive parameters.
