Interface
4.3.2 Analog Output
AO (P3.23)
The analog output is a single-ended signal (with reference to Analog Common (ACOM)
which can represent the following motor data:
• Not Assigned • Phase R Current • Iq Current
• RMS Phase Current • Phase S Current • Id Current
• Peak Phase Current • Phase T Current
• Motor Velocity
Motor phase U, V and W corresponds to R, S and T respectively.
MotionView Setup program can be used to select the signal source for the analog
output as well as its scaling.
If the output function is set to “Not Assigned” then the output can be controlled directly
from user’s program. Refer to the PositionServo Programming Manual (PM94P01) for
programming details.
STOP!
Upon application of power to the PositionServo, the Analog Output supplies
-10VDC until bootup is complete. Once bootup is complete, the Analog Output will
supply the commanded voltage.
4.4 Communication Interfaces
4.4.1 Ethernet Interface (standard)
Programming and diagnostics of the drive are performed over the standard Ethernet
communication port. The Drives IP address can be displayed from the drive’s front
panel display. The last octet of the drive’s IP address can be set from the drive’s display.
Changes do not take affect until after a power cycle. The interface supports both 100
BASE-TX as well as 10 BASE-T. This configuration allows the user to monitor and
program multiple drives from MotionView. Refer to section 5.4.1 for PC configuration
information.
4.4.2 RS485 Interface (option)
PositionServo drives can be equipped with an RS485 communication interface option
module (E94ZARS41) which is optically isolated from the rest of the drive’s circuitry.
This option module can be used for two functions: drive programming and diagnostics
using MotionView from a PC (with RS485 port) or as a Modbus RTU slave. The
PositionServo drives support 5 different baud rates, ranging from 9600 to 115200.
Drives are addressable with up to 32 addresses from 0-31. The factory setting for
the baud rate is 38,400 with a node address of “1”. The drives address must be set
from the front panel display of the drive. When used with MotionView software, the
communication speed is also set from the front panel display. If used for Modbus RTU
communications, the Modbus baud rate is set as a parameter within MotionView.
