10.3.1.2 Loop Cable Replacement

Proceed as follows:
Disconnecting cables
1. Disconnect the SAB from its power source (mains
network).
2. Wait for the necessary discharge time to elapse.
3. Disconnect any cables connected to the X3, X4,
or X5 ports on both servo drives for easier access
to the loop cable.
4. Loosen the threaded rings of the loop cable
connectors on both servo drives.
5. Disconnect the loop cable from the servo drives.
Cable replacement
Replace the loop cable with a cable of identical type and
®
length. See the VLT Integrated Servo Drive ISD
Design Guide for part numbers.
Connecting cables
1. Connect the male connector of the loop cable to
the female connector on the servo drive (see
chapter 5.8.2.1 Connecting/Disconnecting Hybrid
Cables).
2. Connect the female connector of the loop cable
to the male connector on the adjacent servo
drive (see chapter 5.8.2.1 Connecting/Disconnecting
Hybrid Cables).
3. Turn the threaded rings hand tight on both servo
drives.
4. Ensure that there is no mechanical tension on the
cables.
5. Tighten the threaded rings of the connectors on
both servo drives.
6. Reconnect any cables that were connected to the
X3, X4, or X5 ports on both servo drives.

10.4 Servo Drive Replacement

10.4.1 Dismounting

The procedure for dismounting the servo drive is the
reverse of the fitting procedure described in chapter
chapter 5 Electrical Installation.
Proceed as follows:
1. Disconnect the supply and wait for the discharge
time to elapse.
2. Disconnect the electrical cables.
3. Dismount the servo drive.
4. Replace the ISD 510 servo drive with an ISD 510
servo drive of the same type. See the VLT
Integrated Servo Drive ISD
Guide for part numbers.

10.4.2 Fitting and Commissioning

The procedure for fitting and commissioning the servo
drive is described in chapter 4.5.3 Fitting Instructions Servo
Drive and chapter 6 Commissioning.
Proceed as follows:
1. Check if preparation is required (see
chapter 4.4.1 Servo Drive).
2. Fit the servo drive (see chapter 4.5.3 Fitting
Instructions Servo Drive).
3. Connect the hybrid cables (see
chapter 5.8.2.1 Connecting/Disconnecting Hybrid
Cables).
4. Connect the I/O and/or encoder cables (see
chapter 5.8.2.2 Connecting/Disconnecting Cables
from Ports X3, X4, and X5).
5. Configure the servo drive parameters according
to the fieldbus used (see chapter 6.2 ID
Assignment).
6. Conduct a test run.

10.5 SAB Replacement

10.5.1 Dismounting
The procedure for dismounting the SAB is as follows:
1. Disconnect the supply and wait for the discharge
time to elapse.
2. Disconnect the electrical cables.
3. Remove the decoupling plate.
4. Dismount the SAB.
10.5.2 Fitting and Commissioning
The procedure for fitting and commissioning the SAB is
described in chapter 4.5.5 Fitting Instructions Servo Access
Box (SAB) and chapter 6 Commissioning.
Proceed as follows:
1. Check if preparation is required (see
chapter 4.4.2 Servo Access Box (SAB)).
2. Fit the SAB as described in chapter 4.5.5 Fitting
Instructions Servo Access Box (SAB).
3. Connect the electrical cables as described in
chapter 5.8.1 Servo Access Box.
4. Switch on the system as described in
chapter 6.3 Switching on the ISD 510 Servo System.
5. Configure the SAB parameters according to the
fieldbus used (see chapter 6.2 ID Assignment).
6. Conduct a test run.
