4.4.3 RS485 Communication Setup

When establishing communication between MotionView and a PositionServo drive, a
communication method must be selected. The connection choice can be either “UPP
over RS485/RS232” or “Ethernet”. The “UPP over RS485/RS232” selection establishes
a RS485 connection between MotionView and the first drive on the network. Multiple
drives can then be added to the network via RS485. Each drive on the network must
have a different Node Address. When setting up communications the node address of
the target drive must be set. MotionView will then send out a communications packet
to the drives on the network, via the RS485 connection. The message, “Device with
address # not present in the network” will appear If the target node could not be found.

4.4.4 MODBUS RTU Support

As a default, the Ethernet and RS485 interfaces are configured to support MotionView
program operations. In addition, the Ethernet port can support MODBUS TCP/IP slave
protocals and the RS485 interface can be configured to support the MODBUS RTU
slave protocol. These interfaces are configured through the MotionView program
environment. When configured for MODBUS operation, the baud rate for RS485 is
set by the parameter “Modbus baud rate” in MotionView. MODBUS RTU requires 8
data bits. The MODBUS RTU slave interface protocol definitions can be found in the
MotionView help menu under “Product Manuals”.

4.4.5 CAN Interface (option)

An optional CANopen communication module (E94ZACAN1) is available for the
PositionServo drive. Installed in Option Bay 1 as P21, the CANopen module is optically
isolated from the rest of the drive’s circuitry. The 3-pin CANopen module is for HW/SW
1A10 and the 5-pin CANopen module is for HW/SW 1B10 or higher. Refer to the PS
CANopen Reference Guide (P94CAN01) for more information.

Motor Selection

The PostionServo drive is compatible with many 3-phase AC synchronous servo motors
as well as 3-phase AC asynchronous servo motors. MotionView is equipped with a
motor database that contains over 600 motors for use with the PositionServo drive.
If the desired motor is in the database, no data to set it up is needed. Just select the
motor and click “OK”. However, if your motor is not in the database, it can still be used,
but some electrical and mechanical data must be provided to create a custom motor
profile. The auto-phasing feature of the PositionServo drive allows the user to correctly
determine the relationship between phase voltage and hall sensor signals, eliminating
the need to use a multi-channel oscilloscope.

4.5.1 Motor Connection

Motor phase U, V, W (or R, S, T) are connected to terminal P7. It is very important
that motor cable shield is connected to Earth ground terminal (PE) or the drive’s case.
The motor’s encoder/resolver feedback cable must be connected to terminal P4. If a
resolver option module is used, connect to terminal P11, and if a second encoder option
module is used, connect to terminal P12.
