7.11.1 Master/Slave Starter Configuration:
In the master / slave configuration, one "master" starter can directly control the output of one or more "slave" starters. To utilize the
master / slave configuration, one starter needs to be defined as the "master" starter. The Starter Type parameter of the "master" starter
should be configured appropriately as a Soft Starter (normal or ID), Phase Controller or Current Follower. If configured as a soft starter,
the acceleration and deceleration profiles need to be configured for proper operation.
To configure a master / slave application:
1. The analog output of the master MX
2
control card needs to be connected to the analog input(s) of the slave card(s).
2. The master MX
2
's analog output needs to be configured. Set the Analog Output Function parameter to option 10 or "0 - 100% firing".
The Analog Output Span parameter should be set to provide a 0-10V or 0-20 milliamp output to the slave starter(s). Adjust analog
output jumper (JP1) to provide either a voltage or a current output. Set the slave MX
2
's Starter Type parameter to Phase Control and
verify that the Analog Input Offset and Analog Input Span parameters are set to accept the master signal.
3. The slave MX
2
needs to be provided with a start command from the master MX
2
. A RUN programmed relay from the master MX
2
can
be used to provide the start command to the slaves. The slave(s) Control Source parameters (Local Source and Remote Source)
settings need to be set appropriately.
4. The slave MX
2
analog input(s) needs to be configured for the appropriate voltage or current input signal type. Set the analog input
jumper (SWI-1) to the desired input type.
For additional master/slave application information, consult the factory.
