Table 1.  Equipment Setup Items

ITEM DESCRIPTION

Material Factor

default: 1.00

min: 0.10

max: 10.00

This specifies the scale factor used in computing flow control (analog output). It can be changed as material viscosity and temperature changes.

Flow Rate Bias

default: 0.00 V

min: -9.99 V

max: 10.00 V

This value will be added to the flow rate voltage while sealing. Most sealing equipment respond only in a linear fashion to voltages within a limited range, often 3 to 8 volts. Use Flow Rate Bias to help compensate for non-linearity in the sealing equipment flow rate response.

Typical values of Flow Rate Bias are between 0.0 and 2.0 volts. To determine the appropriate value for your dispensing equipment, contact your dispensing equipment supplier or determine the value yourself by generating a voltage-in to sealant-out chart. Use the chart to find the flow rate bias by drawing a line through the region of the chart that has the most linear response. The point where this line crosses the voltage axis is the flow rate bias.

Minimum Flow Command

default: 0.00 V

min: 0.00 V

max: 10.00 V0

This specifies the minimum flow command voltage that will be sent to the dispensing equipment while sealing. If the requested flow rate specified in the current Seal Schedule ever goes below the Minimum Flow Command, the Minimum Flow Command will be sent to the dispensing equipment.

Flow Command AOUT Type

values: Volts, Current

default: Volts

This selects the type of analog output:

  • Volts - Type II output - range 0-10 volts

  • Current - Type III output - range 1-5 volts

Style ID ack time-out

default: 0 msec

min: 0

max: 30,000

An error "SEAL-246 Style ID communication timeout (E%s)" will be posted if the dispenser does not raise the IN_PROCESS signal within the time specified by this item after Style_strobe output is turned on by the robot.

Dispense Complete time-out

default: 0 msec

min: 0

max: 30,000

"SEAL-305 Dispense complete timeout (E%s)" will be posted if the dispenser does not turn off the IN_PROCESS signal with the time specified by this item after Dispense_Complete output is turned on by the robot.

Fault Reset pulse width

default: 300 msec

min: 0

max: 3,000

This item specifies the pulse width of the "fault reset" signal from the robot to the dispenser. Fault reset will be automatically attempted when the robot detects the major fault signal on or the dispenser ready signal off before sending the style ID or before resuming a paused program.

Fault Reset time-out

default: 2000 msec

min: 0

max:30,000

"SEAL-308 Fault Reset Timeout (E%s)" will be posted if the dispenser does not turn on the dispenser ready signal or if the dispenser does not turn off the major fault signal within the time specified by this item after the fault reset signal is asserted by the robot.

Note

The time-out error will not be posted if the robot is running dry (dispensing disabled).

Rmt Start/Purge time-out

default: 10,000 ms:

min: 0

max: 30,000

At the beginning of a job, if dispenser ready DI is not ON, the robot initiates a remote start sequence by setting the Remote start digital output. If the dispenser ready input does not turn ON within this time, the following error is posted:“SEAL-314 Rmt Strt/Purge Request Timeout”

Set Task OK upon recovery

values: ENABLE, DISABLE

default: ENABLE

If enabled, the robot sets the Task OK signal on when you select one of the following error recovery options: Continue Weld/Wet or FastFaultRecovery.

Bead shaping factor*

default: 1.00

min: 0.01

max: 10.00

This specifies the global scale factor used in computing atomizing air. Changing this factor has an effect on all atomizing air values specified in sealing schedules.

Bead shaping AOUT type*

values: Volts, Current

default: Volts

This selects the type of the analog output:

  • Volts - Type II output - range 0-10 volts

  • Current - Type III output - range 1-5 volts

Bead shaping max out*

default: 10.00 V

min: 0.00 V

max: 10.00 V

This sets the maximum analog voltage for atomizing air for the dispensing equipment. If the intended analog voltage exceeds this value, then an alarm will occur. Maximum voltage will not exceed this value.

Use default ACC

values: ENABLE, DISABLE

default: DISABLE

This item enables/disables the Default Acc feature.

Default ACC

default: 20

min:

max:

If Default Acc is enabled, the valued specified in this item will be used as Acc (acceleration) value for all motions that do not have the Acc modifier. If the Acc modifier is specified in the teach pendant program, the specified Acc value is used instead of the default Acc value.

This feature allows the dispenser with slower response time to follow the flow command changes due to robot speed variation.

User def recvry delay

default: 0.00 msec

min:

max:

This item adjusts the gun open timing when the gun is reopened after fast fault recovery. A positive value will open the gun earlier by the specified amount of time.

Guns Used in Calibration

default: INCOMPLETE

min: 1

max: 6

This specifies the guns that DispenseTool will use in equipment calibrations. Up to six guns can be used. Guns can be used only if they have been defined during DispenseTool configuration. The Gun Selection for Calibrations item displays the status of the six possible guns using a six-character expression. The first character represents gun 1, the second character represents gun 2, the third character represents gun 3, and so on. If a gun has not been defined, it is represented by a*. You cannot change the value of a gun that has not been defined. If a gun has been defined, you can specify whether it will be used during calibration:
  • Thegun number indicates that the gun will be used.

  • Theminus symbol, "- ", indicates that the gun will not be used.

    To change the value of a gun that has been defined, use the appropriate function keys.

3.  SETUP FLOW RATE CALIBRATION SCREEN

Flow rate control calibration will lead you through a sequence of operations that will set up a scale factor for the current flow rate type. This calibration runs a sample program (MOV_SEAM, by default) and asks you to measure and enter the actual sealant dispensed. The robot uses this information to calculate the scale factor for the flow rate type.

Table 3.  Flow Rate Control Calibration Items

ITEM DESCRIPTION

Calibration Status

This item displays the calibration completion status for the selected flow rate type.

  • DEFAULT indicates that calibration has not been performed for the selected flow rate type and that the scale factor for the selected flow rate type is still 1.0.

  • COMPLETE indicates that calibration has been performed successfully for the selected flow rate type and that the scale factor for the selected flow rate type probably is not 1.0.

Seal Schedule in MOV_SEAM value: 30

This item indicates the sealing schedule that must be used in the current sample program, which is MOV_SEAM in this case. The information in this sealing schedule will be used to calculate the scale factor for the flow rate type in the specified schedule.

Flow Rate Type

This item indicates the flow rate type that will be used in this calibration. You must set this to the flow rate type you are using in the calibration. Editing this item is the same as editing Flow rate type in the specified sealing schedule, which is sealing schedule 30 by default.

Desired Flow Rate

This item indicates the target flow rate that will be used for this calibration. Set this to the flow rate that will be used most often in your process. Editing this item is the same as editing Flow rate type in the specified sealing schedule, which is sealing schedule 30 by default.

Sample Program default: MOV_SEAM

This item indicates the program that will be run as part of this calibration. The sample program should dispense a simple seam at a steady speed so that you can measure the dispensing rate manually and enter the results into the robot. The sample program must use only SS[30] (where 30 is the number defined in the Seal sched used in MOV_SEAM item) to start sealing. No other SS should be used in this program. A default MOV_SEAM program is provided that includes the appropriate instructions. To use the default program, touch up the positions.

Home Program default: MOV_HOME

This item indicates the name of a program that moves the robot to the home position. When you perform this calibration, you have the option of running this program before and after you run the sample program, to ensure that the robot starts and ends the calibration at the home position.

TCPP BW Scale Factor

This item shows the result of the linear flow rate calibration.

TCPP BW Sqr-scale Factor

This item shows the result of the square flow rate calibration.
