Output On/Off Synchronization Appendix D

Synchronizing Multiple Mainframes

The output turn-on synchronization function can be used across multiple mainframes that have coupled output channels. Each mainframe that will be synchronized must have at least one coupled channel. Note that cross-frame synchronization must be enabled for any mainframe that contains synchronized output channels.

Procedure

1.Configure the output channels on each mainframe as described in steps 1 through 3 of the previous procedure.

2.This step is required if you have power modules with different minimum delay offsets. Specify a common delay offset for all of the synchronized output channels. This value must be the largest delay offset of all synchronized output channels regardless of the mainframe in which they are installed. This same value must be specified as the common delay offset for each mainframe.

3.Connect and configure the digital connector pins of the synchronized mainframes as described in the following section.

Digital Connections and Configuration

 

Only pins 4 through 7 can be configured as synchronization pins. You cannot

NOTE

 

configure more than one ON couple and one OFF couple pin per mainframe.

 

The polarity of the pins is not programmable.

 

 

 

The digital connector pins of the synchronized mainframes that

 

contain coupled channels must be connected together as shown in

 

the following figure. In this example, pin 6 will be configured as the

 

output On control. Pin 7 will be configured as the output Off control.

 

The ground or Common pins also need to be connected together.
