Performing Parallel Operation
During parallel operation, the slew rate and response speed settings on the master unit are
used. The maximum slew rate is the maximum value on the master unit.
If a unit on which the response speed has been set to 1/1 is set as the master unit for parallel
operation, its response speed is changed to 1/2 to ensure operational stability. You can use
the menu settings to return the response speed to 1/1.
If large voltage drops occur because of increased wiring inductance or if oscillations occur
due to instability of the product caused by current phase lag, reduce the response speed to
ensure stable operation.
Turning the power on and off
■
Turning the power on
1
Turn the POWER switches of all slave units on.
2
Turn the master unit’s POWER switch on.
■
Turning the power off
There is no set order for turning the power off. Turn all the electronic loads off.
Alarms during parallel operation
If an alarm occurs during parallel operation, an error message is displayed, and all electronic
loads turn their load off. If the alarm occurred on a slave unit, “ALARM EXTERNAL” is
displayed on the master unit. Clear the alarm on the master unit.
