manual.
Failure to follow these instructions can result in death, serious
injury, or equipment damage.
Cable Routing Practices
Routing Cable in a Building
When wiring ATV21 drive controllers to the field bus, follow all wiring
practices required by national and local electrical codes. Also observe the
following guidelines:
•
Avoid areas of high temperature, moisture, vibration, or other
mechanical stress.
•
Secure the cable where necessary to prevent its weight and the weight
of other cables from pulling or twisting the cable.
•
Use cable ducts, raceways, or other structures to protect the cable.
These structures must not contain power wiring.
•
Avoid sources of electrical interference that could induce noise into the
cable. Use the maximum practical separation from such sources.
When planning cable routing within a building, follow these guidelines:
•
Maintain a minimum separation of 1 m (3.3 ft) from the following
equipment:
— air conditioners and large blowers
— elevators and escalators
— radios and televisions
— intercom and security systems
— fluorescent, incandescent, and neon lighting fixtures

Routing Cable in Electrical Equipment
Rooms
© 2007 Schneider Electric All Rights Reserved
When wiring in electrical equipment rooms or large electrical equipment
line-ups, observe the following guidelines for cable segregation and
separation of circuits:
•
Use metallic conduit for all drive controller wiring. Do not run control,
network, and power wiring in the same conduit.
•
Separate non-metallic conduits or cable trays carrying power wiring from
metallic conduits carrying low-level control network wiring by at least
305 mm (12 in.).
•
Separate metallic conduits carrying power wiring from those carrying
low-level control network wiring by at least 76 mm (3 in.).
•
Whenever power and control wiring cross, the metallic conduits and
non-metallic conduits or trays must cross at right angles.
•
If necessary, use filters to attenuate conducted emissions from the drive
controller to the line to prevent interference with telecommunication,
radio, and sensitive electronic equipment. Contact your Schneider
Electric representative for selection and application of electromagnetic
interference (EMI) filters.

For additional information, refer to NEMA ICS 1.1 (latest edition), “Safety Guidelines for the
Application, Installation, and Maintenance of Solid State Control” and to NEMA ICS 7.1 (latest
edition), “Safety Standards for Construction and Guide for Selection, Installation and Operation
of Adjustable-Speed Drive Systems.”
Selecting Local or Remote Mode
DANGER
UNINTENDED EQUIPMENT OPERATION
• Know the state of the frequency and run commands from the remote
source before exiting the local mode.
• Upon entering the remote mode, the drive controller will respond to the
most recent command from the remote source, even if it was received
before entering or while in the local mode.
Failure to follow these instructions will result in death or serious
injury.
Use the LOC/REM key on the drive controller’s keypad to switch between
local and remote mode.
The LOC/REM key can be disabled by setting parameter F732 to 1.
When parameter F295 is set to 1 (factory setting), a bumpless transfer of
motor operation is achieved when switching from remote to local mode. For
example, if the bumpless transfer feature is active and if the motor is
running at full speed with the drive controller in remote mode, the motor will
still run at full speed after the drive controller is transferred to local mode.
Conversely, when switching from local to remote mode, the run and speed
command is not transferred to the remote mode. Upon entering the remote
mode, the drive will operate on the run and speed command set by the
remote source even if it was received before entering or while in the
local mode.
Refer to Figure 5 on page 17 for an example timing diagram.

Configuration
Control Configurations
30072-451-97A
09/2007
There are three means of controlling the drive controller with the option card
installed:
•
•
•
The drive controller keypad
The BACnet network
The drive controller terminals
The keypad has priority when the LOC/REM key is in the LOC (local)
position. To switch to network or terminal control, set the LOC/REM key to
the REM (remote) position. See “Selecting Local or Remote Mode” on
page 16.
To allow switching between network and terminal control, assign the forced
local function to:
•
•
Logic input F by setting parameter F111 to 48, or
Logic input R by setting parameter or F112 to 48
In addition, you must set binary output points 11 (SPTSEL) and 12
(CMDSEL) according to Table 6 to define the switching behavior of the
speed reference and command channels.

Additional Functions
The BACnet card provides the additional functions described in this section.
Full Parameter Access
With indirect access, it is possible to read or write to any of the internal drive
controller parameters using the following four objects:
•
•
•
•
MBOX DATA
MBOX PARAM
MBOX READ
MBOX WRITE.
To read the value of a parameter:
1. Write the logic address of the parameter to the present value property of
the object MBOX PARAM.
2. Set the present value property of the object MBOX READ to “read”.
The current value of the parameter can be read in the present value
property of MBOX DATA.
To write a value to a parameter:
1. Write the logic address of the parameter to the present value property of
the object MBOX PARAM.
2. Write the new value in the present value property of the object
MBOX DATA.
3. Set the present value property of the object MBOX WRITE to “write”.
NOTE: MBOX READ and MBOX WRITE automatically become inactive
once a command is sent. They always return a “0” when read.
Drive Controller Identification
Information about the drive controller is stored in a unique object called
ATV21 (Device object type). Table 24 lists the properties of this object.
These properties are formatted as a character string.
