Control
Command control includes instructions such as Stop, Run, Jog, etc. The source of the Command
signal must be established for normal operation.
Frequency commands control the output speed of the Q9 Plus ASD. The source of the frequency
(speed) control signal must be established for normal operation.
The source of the command control and speed control may be either internal or external. Once the signal
source is selected for either function, the system may be configured to use the selected signal all of the
time or switch under user-defined conditions.
