INPUT MONITORING
These MVs monitor the M–Traverse's inputs.
MV-41 LEAD FREQUENCY
The Lead Frequency displays the frequency of the Lead Frequency Input (J3, pin 3, 4,
5) in hertz (pulses per second). MV-41 is averaged; it is the 250 millisecond frequency
calculation prior to the display update.
MV-42 FEEDBACK FREQUENCY
The Feedback Frequency displays the frequency of the Feedback Frequency Input (J3,
pin 7, 8, 9) in hertz (pulses per second). MV-42 is averaged; it is the 250 millisecond
frequency calculation prior to the display update.
MV-53 DISCRETE INPUTS - GROUP A
The Discrete Inputs - Group A displays the status of the Jog, Jog Forward/Reverse,
Run, Wait, F-Stop, and Keypad Lockout discrete inputs. The number “1” indicates an
open, or logic high level. The number “0” indicates a closed, or logic low level (shorted
to common). In the example below, “Jog Forward/Reverse” is the open or logic high
level.
