it is advantageous to check that the drive’s common serial communication data
rate is set to its maximum speed. Because the gateway will communicate to
each drive only at the drive’s configured data rate, this will provide the fastest
response time for drive-to-network data transfers. For information on checking
the drive’s common serial communication data rate, refer to the appropriate
manual supplied with your drive.
Note that the common serial communication parameters of each drive are
handled independently by the gateway, which means that different drive
families may be connected to different channels of the unit in any combination,
and that the drives connected to each channel may simultaneously
communicate to the unit at completely different baud rates, parity settings, etc.
Drives can be connected to the gateway on any ASD channel in any order or
combination. When more than one drive is connected to the unit, or if the
optional auxiliary power supply is used, the gateway will draw its control power
from the source with the highest power supply voltage.
Installation of the gateway should only be performed by a qualified technician
familiar with the maintenance and operation of the connected drives. To install
the gateway, complete the steps outlined in the following sections related to
your specific drive.
3.3.1 Installation for G7 ASDs
1. Mount the unit via the desired method (refer to section 3.1).
2.
CAUTION!
Verify that all input power sources to the drives to
be connected have been turned OFF and are locked and tagged out.
3.
DANGER!
Wait at least 5 minutes for the drive’s
electrolytic capacitors to discharge before proceeding to the next step. Do
not touch any internal parts with power applied to the drive, or for at
least 5 minutes after power to the drive has been removed. A hazard
exists temporarily for electrical shock even if the source power has
been removed. Verify that the CHARGE LED has gone out before
continuing the installation process.
4. Remove the drive’s front cover / open the drive’s cabinet door (refer to the
appropriate drive manual for instructions how to do this).
5. The drive’s LCD panel (also called the “Electronic Operator Interface” or
“EOI”) can communicate with the drive via either the RS485/RS232
channel (CNU1/CNU1A) or the common serial channel (CNU2/CNU2A).
Because the gateway uses the common serial channel, the LCD panel
must be configured to use the RS485/RS232 channel. If the drive to be
connected is currently using CNU2 (on the drive control board) and
CNU2A (on the LCD panel), then this connection must first be switched
