CxLetterScan General Settings
Here you will find all available settings for the CxLetterScan module. These are the global settings that are valid for all modules. Among them are also the parameters for AutoSpeed (400 - 430), this is a function that is active under all use cases. With this the tape speed is controlled automatically, so that as few errors and timeouts as possible are triggered. The values are all given as a percentage, and the percentage range of the tape speed is always based on the set speed. This feature cannot be switched off.

General settings
| Designation (Custfieldname) | Default value | Value (Table ID: 2291, lID = 0) |
| 110: AutoStopp: Time in seconds until the machine stops when no shipments are processed. | 30 | If Autostop is activated in the control, the machine is stopped after a defined time if no letter has been read in. This waiting time can be defined between 1 and 999 seconds. |
| 111: Motor ramp to start and stop the tape, a multiple of 50 milliseconds. | 60 | The motor control is always based on a ramp. The ramp determines how long the acceleration of the motor from 0 to 100% should take. |
| 120: Speed reduction: Value of the belt speed in mm/s when the machine is ready. Value range: 0 - 700 mm/s | 200 | When there are no more shipments on the machine, the belt speed is lowered to the set belt speed, so that the machine and the treadmill can be spared. |
| 121: Speed reduction: Time in seconds after processing the last transmission of a batch until the belt speed is reduced. Value range: 0 - 60 seconds | 10 | Time to wait after the last transmission before using the tape lowering speed. |
| 122: Speed reduction in use case Manual Capture: Time in seconds after processing the last transmission of a batch until the tape speed is reduced. Value range: 0 - 255 seconds | 60 | Time which is waited after the last transmission until the tape lowering speed is used, but only valid if the use case 'Manuel Capture' is used. |
| 123: Minimum belt speed in mm/s. (40 - 100 mm/s) | 80 | This setting defines the lowest possible belt speed at which the machine can run. The default setting defines the speed at which the belts will still turn, anything below this will not make sense as the motor will not turn enough to move the belts. If a speed below this is set, it will automatically be increased to this minimum speed. |
| 124: Maximum belt speed in mm/s (300 - 700 mm/s) | 700 | This setting defines the maximum possible belt speed at which the machine can run. The value can be set from 300 to 700 mm/s, where 700 mm/s is the highest speed at which the machine can still function correctly. Please note that depending on the processing of a letter (extensive image analysis, etc.), this speed may be too high. Please note!!! If you change this setting, it is mandatory to restart CodX PostOffice, because this setting is a basic setting for the machine control and cannot be changed at runtime. |
| 130: Speed stroke in % for the belt speed per module | 5 | This setting defines the increase of the belt speed from one module to the next in percent. The order of the modules results from their programming, i.e. first the camera module, then the printer module and then all sorting modules. The belt speed is programmed in this order, each with a speed increase of x percent.
This speed increase can be defined between 0 and 20 percent. Please note that the 2nd motor of the Cameramodule is also calculated with the speed increment. The value must be set so that envelopes of all sizes are easily pulled from the front belt. 5% can be used as a base, then gradually increase the value to a maximum of 8% or reduce it to a minimum of 3% if necessary. The target value is as low as possible. |
| 150: Idle mode: Maximum permissible belt speed as a percentage of the effective machine speed when the machine is running in idle mode. | 300 | This factor is used to specify the belt speed in mm/s for moving empty. This is a percentage of the maximum possible belt speed. |
| 160: Empty run: Time in seconds that the machine runs empty until an error occurs if there are still letters on the machine. Value range: 0 to 60 seconds | 30 | This time factor can be used to prevent the machine's idle mode from lasting too long. Possible cause is that someone continues to hang up transmissions or the feeder is permanently covered. |
| 210: Shipment length: Shortest permissible length of the shipment in the direction of travel in mm. Value range: 50 to 500 mm | 140 | Shortest item length that is allowed. Please make sure that you make this length long enough to get an image at this minimum length for skewed feeds. |
| 220: Shipment length: Longest permissible length of the shipment in the direction of travel in mm. Value range: 50 to 500 mm | 330 | Maximum mail length that is allowed. This allows double prints (overlapping letters) to be detected. |
| 310: Machine status: Time interval in milliseconds for querying the machine status. | 100 | The machine status is queried cyclically so that errors on the machine are detected. This cycle can be changed, between 10 and 32768 milliseconds. |
| 311: Board test: Time interval in milliseconds to execute the board test | 200 | When a module is tested with the board test, the board test function is called cyclically on the module and status messages are transmitted to the software. This cycle can be defined between 10 and 60000 milliseconds. |
| 320: Timeout End: Maximum permissible processing time for saving the data in seconds. | 10 | Maximum time in seconds that may be used to save a program. If the time is above this, an error is triggered and the machine is stopped. |
| 400: Maximum processing time in % at which the belt speed is set to the lowest belt speed (430). | 80 | Based on the current belt speed, each letter is given a certain amount of time that it can consume as a maximum for a process. When this time is reached as a percentage of the set value, the belt speed is immediately set to the factor (see 430). This is to prevent a letter taking longer to process from triggering a timeout. This value is set as a percentage of the maximum processing time from 1 to 100. |
| 410: Average processing time in % at which the belt speed is set higher or lower by a factor (420). | 50 | This percentage of the processing time defines when the belt speed is to be increased or decreased by the factor (see 420). As soon as a process approaches more than this factor in percent of the maximum processing time, the belt speed is lowered by a factor (see 420) to a minimum of the lowest possible belt speed (see 430). If no process needs more than this factor in percent of the maximum processing time, the tape speed is increased by (see 420), up to the maximum set speed (the tape speed set by the user in the user interface). Possible values are from 1 to 99 percent. |
| 420: Tape speed factor in % by which is increased or decreased. | 50 | This is the factor in percent by which the belt speed is increased or decreased, depending on whether the processing time needs to be above or below the factor of the average processing time of a process (see 410). Possible values are from 1 to 99 percent. |
| 430: Smallest possible belt speed in mm/s that is set at maximum processing time (400). | 300 | When the maximum processing time of a process (see 400) is reached, the belt speed is reduced to this factor in percent. Possible values are from 1 to 700 mm/s. |
| 440: Delay in milliseconds for motor control | 200 | This value controls the delay for switching the speed up or down between modules. The default value is set to 200 milliseconds, possible settings are from 0 to 1000 milliseconds. This delay does not apply between sort modules if there is more than one. Example with 200 ms delay when speeding up: Sort module 2: new speed Sort module 1: new speed Print module: new speed Wait 200 ms Camera module motor 2: new speed Wait 200 ms Cameramodul motor 1: new speed To slow down, the reverse order applies. |
| 450: I-component for the PID controller of the motor control (0.00 - 100.00) | 2.0 | Control factor I component for the PID controller. (For more detailed information on the functioning and setting of the PID controller, read WS article WS#79550). |
| 460: D-component for the PID controller of the motor control (0.00 - 100.00) | 0.0 | Control factor D component for the PID controller. (For more detailed information on how the PID controller works and how to set it, read WS article WS#79550) |
| 470: P-component for the PID controller of the motor control (0.00 - 100.00) | 0.4 | Control factor P component for the PID controller. (For more detailed information on how the PID controller works and how to set it, read WS article WS#79550) |
| 480: Cycle [s] in which the PID initial values in the modules are updated (0 = off, 1 = 3600 seconds). | 60 | When the settings for the PID controller are changed, these are written to the modules. This happens at the interval specified here. For production systems that are well set, this value can either be set to 0 (disabled) or very high. |
| 490: Cycle [ms] in which the PID regulator of the firmware calculates the values (1 - 10000 milliseconds) | 1 | The interval at which the PID controller is recalculated in the firmware. The best setting so far is 1 millisecond based on experience. The value can be changed from 1 to 10000 milliseconds. The longer the interval, the longer it takes to settle to the correct speed. |
| 500: Disable selective USB power saving | Enabled | If this option is enabled, the power saving function on USB devices is disabled when CodX PostOffice is started. This prevents a control unit or print module from going to sleep because of the power saving feature. |
