Err Cts for MOP
P3-04 = 100
P3-04 Error Counts for MOP Adjustment Q Q Q Q
When P3-01 is set to Enable w/ MOP, this function watches how much error is occurring in the registration. Consistent
registration error would indicate that the gear ratio setting P1-02 and P1-03 are not set perfect. The registration count
error is summed up in monitor U1-59. When the total is greater than the P3-04 setting, the MOP ratio U1-57 gets
incremented by 0.0001 each time.
Max Correct/scan
P3-05 = 10
P3-05 Maximum Registration Correction Per Scan Q Q Q Q
When starting a new product batch or starting the machine, there may be a lot of registration error on the first couple of
registration marks. This parameter limits the rate of correction. The default setting of 10 will allow 10 counts of correction
every 5 ms scan. On a 1024 PPR encoder this is 30 rpm. Setting this number too high will allow the registration control to
make abrupt corrections when the error is large.
Serial MOP Cntl
Disable
P3-08 Serial MOP Ratio Control Q Q Q Q
Setting Description
0 Disabled. Serial control of Modbus ratio is disabled.
1 Enabled. Allows serial communication to set the value of the MOP
ratio using Modbus address 05a8H. The value sent to address 05a8H
is divided by 10,000 to determine the final ratio. No enter command is
required after writing the information to address 05a8H.

Factory Default: 0
Modbus Address: 05a7H
Setting Range: 0 to 10,000
