D/A monitor option D1

Calculation of	PG =
physical parameter
using the measured	PG:
value:	MW:
	BG:
	VS:

MW * BG

VS * 10V

physical parameter

voltage on output channel in [V] reference value from the above table gain factor

Example: P76 = 4.000 0010 P77 = 13.000 0005 Therefore the following applies:

channel 2: measuring parameter 4 (actual speed value). gain factor = 10

channel 3: measuring parameter 13 (phase current for phase U). gain factor = 5

measured values:

channel 0:MW=2.5V=> PG =	2,5	* 20000min	− 1
				=500 rpm
		10 * 10V
channel 1: MW = 3V => PG =	3 *	200A = 12A
	5 * 10V

The parameters of the D/A monitor can also be set to status S15 or be viewed via the optimization display (see Page 133).

7.9.7 D/A monitor option D1

The measuring parameters are selected using P73 or P74

The option D1 cannot be used for COMPAX 1000SL.

This option provides you with two additional analogue output channels with a resolution of 12 bit. These channels are updated every 100 µs. Use the parameters P73 and P74 (as you do with the service D/A monitor) to select 2 quantities and to adapt them to the required measuring range using 2 parameters (P71 and P72). D/A monitor option D1 must be ordered as a separate item.

To obtain output from the measured signals, you will need an externally connected monitor box (ASS1/01) with 2 BNC bushes for connecting the measurement instruments. This is connected as follows:

!monitor box is connected to COMPAX connector X17.

!the initiator line is connected from X17 to the monitor box. The signals are fed through the monitor box.

Meaning and range of values of P71 - P74

No.	Parameter	Range
P71	Gain factor from channel 0.	1...10 000
P72	Gain factor from channel 1.	1...10 000
P73	Measuring parameter of channel 0. (For the meaning, see	0...18
	table on Page 56).
P74	Measuring parameter of channel 1. (For the meaning, see	0...18
	table on Page 56).

The parameter can only be actuated once you have entered the password.

Example:P71=10 P72=5 P73=4 P74=13 Therefore, the following applies:

channel 0: measuring parameter 4 (actual speed value). gain factor = 10

channel 1: measuring parameter 13 (phase current for phase U). gain factor = 5
