10V * VS
BG * MW
PG =
PG: physical parameter
MW: voltage on output channel in [V]
BG: reference value from the above table
VS: gain factor
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=>
10V * 10

PG = = 12A
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 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
table on Page 56). 0...18
P74 Measuring parameter of channel 1. (For the meaning, see
table on Page 56). 0...18
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
