3.2 Monitoring values description
otee:
N
for DriveSynch Systems:
In a DriveSynch system, only Master drive monitoring
signals are reliable.
Only directly measured values are reliable in follower units.
Even the Output Frequency of DriveSynch follower is not
directly observed and thus may not show actual output
frequency that is controlled by DriveSynch Master Drive.
V7.1
Output frequency
[#,## Hz] ......ID1
Output frequency to motor, updated at 10 ms
time level.
V7.2
Frequency reference
[#,## Hz] ......ID 25
Frequency reference to motor control, after
speed share function. updates at 1 ms time level.
V7.3
Motor speed
[ # rpm]
ID 2
Motor speed in rpm
V7.4
Motor current
[A] ...............ID 3
Open loop:
1 s linear filtering.
Closed loop:
32 ms filtering
Drive Synch Operation Master drive:
This value is the total current of the system
divided by number of drives in the system
(SbLastID). SbLastId cannot be changed;
it needs to be set according to how many
drives are linked with system bus.
Drive Synch Operation Follower drive:
This value is the current of the drive’s own
power unit.
Current scaling in different size of units

ID 4
In % of Motor nominal torque
Open loop:
1 s linear filtering
Closed loop:
32 ms filtering
Drive Synch Operation Follower drive:
This value is the torque of the drive’s own
power calculated in open loop. Motor torque is
valid only in Master drive.
V7.6
Motor power

ID 5
Calculated motor power
V7.7
Motor voltage V
ID 6
Calculated motor voltage
V7.8
DC link voltage V
ID 7
Measured DC voltage, filtered.
V7.9
Unit temperature oC
ID 8

ID 9
Calculated motor temperature
105 % is tripping limit if response is fault.
V7.11
Analog input 1

ID 13
V7.12
Analog input 2

ID 14
Unfiltered analog input level.
0 % = 0 mA/0 V, –100 % = –10 V, 100 %
= 20 mA/10 V.
Monitoring scaling is determined by the option
board parameter.

V7.14
Analog input 4

ID 28
It is possible to adjust this input value from
fieldbus when the input terminal selection is 0.1.
This way it is possible to adjust the free analog
input from fieldbus and have all analog input
functions available for fieldbus process data.

V7.21
Power reference
%
ID 1700
Power reference monitoring value. If power
reference is not selected in the reference
group it can be directly written to this
monitoring variable from fieldbus and only
ramping rate function is active from power
reference group.
V7.22
PT-100 Temperature Cº
ID 42
Highest temperature of OPTB8 board. 4 s filtering.
