6.1 Connecting the Components
1. Connect the mains supply line to the power
supply module and the control terminal strip of
the power supply module in accordance with the
wiring diagram in the
VLT
®
ISD 410 Design Guide .
2. Connect the DC supply from the power supply
module to the connection box and wire the
safety circuit.
3. Connect the feed cable from the connection box
to the first servomotor by connecting the cable
leads on the connection box and the servomotor
using the threaded connectors.
4. Using the loop cables intended for this purpose,
connect the other servomotors in the group.
5. Fit a CAN terminating resistor on the last
servomotor.
6. Connect the CAN bus to the connection box.
7. Connect the encoder box (if present) and the
power supply module to the CAN network.
6.2 CAN-ID Setting
The default ID of the connection box is preset to 110. All
the settings can be read from the object dictionary.
There are several ways to set/change the CAN-ID. The
easiest way is setting via the BCD switch. The ID setting
should be executed in an unpowered state.
BCD switch is set to 0
•
The ISD ID setting protocol can be used to give
another ID to the box.
BCD switch is set to between 1 and 9
•
The CAN-ID is calculated by the preset value of
110 + the value of BCD switch.
The message for the ID setting over CAN bus is shown in
Table 6.1 . Note that the first 4 bytes have to be 0,
otherwise the connection box will ignore the ID setting
message. This is also the case if the BCD switch is not set
to 0. After this message is sent, the new CAN-ID will start
blinking on the connection box display. Press the <SET>
button on the connection box to accept the new ID. The
connection box will only leave this ID setting mode
following the acceptance of the new ID or after sending an
NMT reset communication.
Note that the other ISD servo system components will also
be in ID setting mode after this message is sent, so an
“NMT reset communication” message has to be sent to
release all devices from this mode.
Note that whilst in ID setting mode, it is not possible to
communicate with the device. An NMT reset communi-
cation leaves the ID setting mode for the connection box
without changing any other state. This ensures that drive
operation is not interrupted. The new ID is then valid
when the connection box has been power cycled or the
NMT reset node message has been sent to the connection
box.

6.3 Functional Operation Test
Always check the following items before initial commis-
sioning, before commencing operation after extended
downtime, or before commencing operation after motor
overhaul:
•
Are all threaded connectors of mechanical and
electrical components firmly tightened?
•
Is the free circulation of cooling air (inlet and
outlet) assured?
•
Are the devices for protection against
overheating (temperature sensor monitoring)
operational?
•
Are the electrical connections OK?
•
Is contact protection in place for rotating parts
and surfaces that can become hot?
