20.ANALOG INPUT #1 HIGH ENGINEERING UNITS (EGU)

USE PARAMETER #18 TO SELECT THE MAXI- MUM ANALOG INPUT #1 EFFECT.

RANGE OF VALUES: FFFE 7961h to 0001 869Fh -99,999 to +99,999 (dec.)

Default Value: 0000 06D6h

1750 (decimal)

(See Parameter 14 for the definition

and purpose of EGU) Parameter #20 sets the maximum level for

effectiveness of Analog Input #1 at the highest signal level.

Assume that the maximum speed of the 1750 RPM motor is set to 12500 EGU’s in parameter #14 (representing, perhaps, 125.00 RPM on an extruder screw) and the Analog input is set for a Speed Reference Input of 0 to +10VDC. The default value of parameter 20 is 1750. This means that when 10VDC is present at Analog Input #1, the resulting speed will be 1750/12500 = 14 percent of maximum speed, or 245 RPM.

Now, if we want to set the maximum speed of this system at 100.00, we set a value of 10000 in parameter #20. This means that when 10VDC is present at Analog Input #1, the motor will run at a speed of 10000/12500 = 80 percent of the maximum speed of the motor, or 1400 RPM. (see also param- eter #19).

21.ANALOG INPUT #2 MODE SELECT

USE PARAMETER #21 TO SELECT THE PUR- POSE OF A SIGNAL AT ANALOG INPUT #2. RANGE OF VALUES: 0000 0000h to 0000 001Fh

0 TO 32 (decimal)

Default Value: 0000 0000h

0 (decimal)

See parameter #17. The operation of Analog Input #2 is identical to the operation of Analog Input #1, EXCEPT the parameters which set the form of the input signal (#22) and low and high EGU’s ( #23 and #24).

Both Analog Inputs #1 and #2 may be set up as General Purpose Inputs, but all other modes are mutually exclusive. If one of the Analog Inputs is set up as a Speed Reference Input, the other Analog

Input may not be set up as a Speed Reference Input. Attempting to set up a second Analog Input as a Speed Reference Input when one is already set up in that mode will cause the second input to be inopera- tive.

22.ANALOG INPUT #2 SIGNAL CONDITIONING

USE PARAMETER #17 TO SELECT THE FORM OF THE SIGNAL AT ANALOG INPUT #1. RANGE OF VALUES: 0000 0000h to 0000 001Fh

0 TO 32 (decimal)

Default Value: 0000 0000h

0 (decimal)

See parameter #18. Signal conditioning selection for Analog Input #2 is identical to Analog Input #1.

23.ANALOG INPUT #2 LOW ENGINEERING UNITS (EGU)

USE PARAMETER #23 TO SELECT THE MAXIMUM ANALOG INPUT #2 EFFECT. RANGE OF VALUES: FFFE 7961h to 0001 869Fh

-99,999 to +99,999 (dec.)

Default Value: 0000 0000h

0 (decimal)

Analog Input #2 works exactly the same way that Analog Input #1 works. Parameter #23 does for Analog Input #2 what parameter #19 does for Analog Input #1. Refer to parameter #19.

24.ANALOG INPUT #2 HIGH ENGINEERING UNITS (EGU)

USE PARAMETER #24 TO SELECT THE MAXIMUM ANALOG INPUT #2 EFFECT. RANGE OF VALUES: FFFE 7961h to 0001 869Fh

-99,999 to +99,999 (dec.)

Default Value: 0000 0000h

0 (decimal)

Analog Input #2 works exactly the same way that Analog Input #1 works. Parameter #24 does for Analog Input #2 what parameter #20 does for Analog Input #1. Refer to parameter #20.
