M–TRAVERSE CALIBRATION
1) Make sure that the M–Traverse is still in “F–Stop”. If it is not, put the
M–Traverse in “F–Stop” by opening the F–Stop Logic input (J4 pins 9
and 10). Refer to
Installation/Setup: Wiring, F–Stop .
2) Enter the resolution (PPRs) of the feedback sensor in the PPR Follower
(CP-18) parameter by entering the following on the keypad:
Press “Code Select”
Enter “18”
Press “Enter”
Enter the Pulses Per Revolution (PPR) of the feedback sensor
Press “Enter”
The Tach is now scaled for feedback RPMs.
3) If the M–Traverse is using the drive voltage for reference (J1 pin 8),
then set the drive's max speed potentiometer to its minimum setting. If
the M–Traverse is using its internal voltage for reference (no
connection to J1 pin 8) then set the drive's max speed potentiometer to
its maximum setting and set the M–Traverse's scale pot to its minimum
setting (fully counterclockwise). Figure 2-28 shows the location of the
M–Traverse scale pot.
4) The M-Traverse is defaulted for use with bi-directional drives that use
bipolar (positive and negative) voltage commands to indicate the
direction. If you are using a single quadrant (direction) drive, then
change CP-29 to unipolar operation, as follows:
Press “Code Select”
Enter “29”
Press “Enter”
Enter “1”
Press “Enter”
5) Enable the M–Traverse's direct control mode by entering the following
on the keypad:
Press “Code Select”
Enter “14”
Press “Enter”
Enter “2”
Press “Enter”
