3.3 Conveyor

3.3.1 Conveyor Drives

Fig. 3-6 Conveyor Drive Parameters

A) Lane Type

0 = no lane

1 = lane

B) Speed Type

0 = lane does not have its own drive motor

1 = lane has its own drive motor

C) Pulses

Number of belt pulses which corresponds to the entered travel path (D).

The default setting is 100 mm.

D) Travel distance in mm, which corresponds to the entered number of belt

pulses (C). The default setting is 675.

With this value the difference between the actual speed and the indicated

actual value can be adjusted. Please note! A change is only permitted,

if anything has changed at the transformation ratio.

E) Max

Maximum possible speed based on electromechanical limitations. The

actual maximum possible speed is limited by the software. The default

setting is 2300.

With this value a difference between actual speed and entered set value

can be adjusted. Please note! A change is only permitted, if anything has

changed at the transformation ratio.

F) Filter

Number of measured values which are averaged together for the actual

value display. A high number results in a stable display value, although

changes to the display value appear very slowly in this case. The default

setting is 10.

G) CCS

Number of measured values which are averaged together for CCS data

logging. This value must correspond with the CCS software settings. The

default setting is 10.

H) Offset

In the closed-loop control mode, the difference between the setpoint and

the actual value is continuously ascertained. An offset is generated

cyclically from this difference for the motor controller module. The current

offset value is displayed here, and minimum and maximum values can be

entered. The default setting is ± 500.

I) Setup Mode / Closed-Loop Control Mode

Settings can be adjusted at the motor controller module in the setup

mode. Offset for the motor controller module is deactivated.

Settings may not be adjusted at the motor controller module in the

closed-loop control mode. Offset for the motor controller module is

activated.

The default setting is closed-loop control mode.

J) Setpoint / Actual Value

Conveyor speed is changed by entering a new setpoint (white field). The

actual value is displayed in the adjacent field.

K) Motor current

Set speed to1800 mm per minute. Switch the conveyor on a read the an-

alog value. Enter this value to „Max. Analog IN“. Connect the ammeter in

series to the motor and read the actual value (mA). Enter the mA value

to „Max. mA“.

To make check the

Speed

1. Turn the conveyor on and check to see whether or not the belt pulse

sensor switches accurately.

2. Open the conveyor window.

3. Set the speed setpoint to 1000 mm per minute, and set manipulated

variable limiting Ymax to 100%.

4. Open the Conveyor Drives window from the service menu.

5. Make sure that switch I is set to setup mode. If not, click switch I. The

text is changed from “Closed-Loop Control Mode” to “Setup Mode”.

6. In order to determine conveyor speed, time required for 1000 mm of

travel must be checked with the help of a stopwatch and a link pin

identified for this purpose.

7. Set switch I back to closed-loop control mode.

8. Save the system parameters to memory.

3.3.2 Conveyor Adjustment

Fig. 3-7 Conveyor Adjustment – Parameters

A) Conveyor adjustment can be operated either automatically or manually.

For further details refer to Main Window, in the chapter entitled “Software”

in the Operating Instructions.

B) Setpoints can be entered here, actual values are displayed and conveyor

tolerances can be entered. Beyond this, the status displays for the

conveyor units (axis) and error messages which have been triggered by

a PCB or the center support can be viewed. For further details refer to

Conveyor Values in the chapter entitled “Software” in the Operating

Instructions.

C) Setup Mode / Closed-Loop Control Mode

The conveyor side panels can be calibrated in the setup mode. Automatic

adjustment is deactivated for all conveyor side panels.

The conveyor side panels cannot be calibrated in the closed-loop control

mode. Automatic adjustment is activated. The default setting is closed-

loop control mode.

Note!

If a dual lane conveyor with asynchronous speed is utilized, the conveyor

speed for lane 2 must be checked separately using the same procedure.
