5.2 Drive Communication
Review and be familiar with this section completely before applying
power to the system.
Most drives are shipped from the factory already configured for a
particular motor. This can be verified by applying logic power and
monitoring the Status Display. A factory-configured drive will go
through a power-up sequence flashing all segments of the display
before settling out to a number indicating the mode of operation. If
the drive is not configured with a particular motor, the display will
flash a minus sign “-“ indicating that you must enter drive, motor,
and application variable parameters. The remainder of this section
will describe the process of setting up a non-configured drive.
Caution must be taken when applying power to the drive. It is
factory configured to enable upon application of power.
Verify that the hardware Remote Enable (REMOTE) enable
switch is disabled.
The SERVO
STAR has the flexibility to be addressed and controlled
from a single-line or a daisy-chain (MultiDrop) configuration in RS-
232-A, RS-485, or fiber-optic SERCOS interface. The first five
switches of the 10-position DIP located on the top of the drive set
the binary address number for that particular drive. Switch 6 of the
DIP determines the serial communication baud rate for either 9600
BPS or 19200 bps.
The SERVOSTAR cannot be configured for RS-232-A and RS-
485 at the same time.
5.2.1 RS-232-A CONNECTION
The drive can be configured for a RS-232-A single-ended
connection through the C1 connector by wiring the 9-pin mating
connector. To configure for multiple units, the drives must be daisy-
chained across the C7 connectors of each drive. When
communicating to a single line unit the drive’s DIP switch must be
set for a binary 0 address. When communicating to multiple units,
the DIP switch can be set for any binary equivalent number from 1
to 31 (see table below), as desired. You can also communicate with
any or all drives within the daisy chain configuration from any one
RS-232-A port on that chain (called Global Addressing).
5.2.2 RS-485 CONNECTION
The drive can also be configured for RS-485 differential connection
through the same C1 connector by wiring the 9-pin mating
connector for RS-485. No software or hardware changes are
necessary. Setting the drive’s DIP address is identical to that
described for the RS-232.
When addressing multiple units, the drives must be daisy-chained
across C1. You cannot daisy chain across the C7 connector in RS-
485 configuration
