„ Detecting Motor Overspeed
An error is detected when the number of motor rotations exceeds the regulated limit. An overspeed (OS) is
detected when a frequency that exceeds the set value in F1-08 continues for longer than the time set in F1-09.
After detecting an overspeed (OS), the MxC stops according to the setting in F1-03.
„ Detecting Speed Difference between the Motor and Speed Reference
An error is detected when the speed deviation (i.e., the difference between the designated speed and the actual
motor speed) is too great. Speed deviation (DEV) situation occurs after speed agree. The difference between
the speed reference and actual workpiece speed is becomes greater than F1-10 and continues for longer than
the time set in F1-11. After a speed deviation situation is detected, the MxC stops according to the setting in
F1-04.
‹ Using Digital Output Cards
There are two types of MxC digital output cards:
• DO-02C
Relay contact output (DPDT contact)
• DO-08
6 photocoupler output channels (shared commons)
2 (independent) relay contact output channels (NC contact)
