Chapter 1 – Overview
1-2 ACS 600 Master/Follower Application Macro
Checklist for a
Quick Start-up
The installation and start-up procedure of the ACS 600 is explained in the
Start-up Guide and the Hardware Manual. An additional checklist for the
Master/Follower application is given below:
1 Switch off the power supplies of the ACS 600 units. Wait for five
minutes to ensure that the intermediate circuits are discharged.
2 Build the Master/Follower Link. See Chapter 2 – Installation and M/F
Link Specification.
3 Connect the external control signals to the Master. Wire the Run
enable signal of the Master via the fault indicating relay output of the
Followers. See
Chapter 2 – Installation and M/F Link Specification.
4 Switch on the power supplies.
5 Activate the M/F Macro in all ACS 600 drives (Parameter 99.02).
6 On the Master ACS 600: Change Parameter 60.01 MASTER LINK
MODE to MASTER.
7
On the Follower ACS 600: Adjust the parameters according to the
basic set suitable for your application. The Follower Torque Control
and Follower Speed Control parameter sets are given in
Appendix B
– Parameter Settings.
Switch all ACS 600 units to external control with the key on the
Control Panel (there should be no L on the first row of the display).
8
Perform a test run with the motors still de-coupled from the driven
machinery. Give the control signals both through the Master analogue/
digital inputs and from the Master Control Panel. Check the correct
operation of the Master and Follower drives visually (motor & Control
Panel display):
• Start, Stop, Direction and Run enable signals given to the Master
are received by all drives.
• The Master follows the speed reference.
• The Follower follows Master speed reference or torque reference. In
torque control, the window control restricts the excessive speed rise
of the motor. Thus the actual speed of the unloaded Follower is
greater than that of the Master, but does not reach the maximum
speed limit.
9 Disconnect the Control Panels from the Follower drives to avoid
accidental use. See CAUTION! below.
10
Switch off the power supplies.
11 Couple the motor shafts to the driven machinery and switch on the
power supplies.
CAUTION! To avoid contradictory control, the drives coupled to the same
machinery should receive the external control signals only via the Master.
As general rules:
– Connect all external control signals to the Master drive only.
– Never control the Follower(s) with the Control Panel or through a fieldbus
system.
