Sequencing Logic
605C Frequency Inverter
Note:
1.
Jogging is set TRUE once the jog cycle has started, and remains TRUE until the
jog cycle has finished which is when either the stop delay has finished or
another mode is demanded.
2.
Stopping is set TRUE during the stopping cycles commanded by either RUN
going low, JOG going low or if Fast Stop is active.
3.
Once Run and Jog are both FALSE, HEALTHY O/P will be set TRUE.
Transition of States
The transition matrix describes what causes the transition from one state to another, for example
see no. 5 below: the transition from “Ready To Switch On” to “Trip Active” is triggered by
“TRIP” going TRUE.
Refer to the following table and state diagram.
