SPX Advanced application – monitoring values
SPX ADVANCED APPLICATION MANUAL
SVCH0203—October 2017 www.eaton.com
V7.27.2
PI Actual value
ID21
PI Actual value. Actual input is selected by
ID number.
V7.27.3
PI Output
ID23
PI Output before scaling. This value uses PI out
high and low for limiting.
V7.27.4
PI Output scaled
ID1807
Scaled PI Output.
This is used for ID connection. Scaling
function is used to scale value more suitable
for connected signal. e.g. when output is
connected to torque limit actual value need
to be –1000 ...+1000 (–100,0 %..+100,0 %)
But PI Out High and Low can be from
–30000...+30000 to have more accurate
PI control.
3.2.5 Frequency chain
V7.28.1
Frequency reference 1
Hz
1126
Frequency reference before speed share.
Speed Share is used also for reference
direction control.
V7.28.2
Frequency reference 2
Hz
1126
Frequency reference after speed share and
reference adjust but before interpolator.
V7.28.3
Frequency reference
Hz
25
Frequency reference after interpolator but
before second order filtering.
V7.28.4
Frequency reference actual
Hz
1128
Frequency reference for ramp control.
V7.28.5
Frequency ramp out
Hz
1129
Ramp control output.
V7.28.6
Frequency reference final
Hz
1131
Final reference to speed controller. After ramp
generator and after Speed Step function,
used for closed loop speed tuning when used
together with Encoder 1 frequency.
V7.28.7
Encoder 1 frequency
Hz
1164
Encoder frequency, monitored directly
from encoder.
3.2.6 Torque chain
V7.29.1
Torque reference
%
ID 18
Torque reference value before load share.
V7.29.2
Torque reference 3
%
1144
Torque reference after load share. But before
torque step.
V7.29.3
Torque ref final
%
1145
Final torque reference in torque reference
chain, before acceleration compensation and
speed controller output.
V7.29.4
Speed control out
%
1134
Closed loop speed controller output.
V7.29.5
Torque reference actual
%
1180
Final torque reference from speed control and
torque control. Also includes torque step and
acceleration compensation factors.
3.2.7 Counters
Below counter values are not visible as a standard
monitoring signal but are accessible with ID numbers
from fieldbus.
3.2.7.1 Power on time counter
This timer is counting when control board is powered
(i.e. counting when only 24 Vdc is given to control board).
ID10 PowerOnTimeTripCounter
Resetable power on time counter.
UINT value. READ only access.
Use ID1050 to define format.
Use ID1051 to reset value
ID1050 PowerOnTripCounterUnit
Read or select power on counter format.
USINT value. WRITE access.
1 = 1 ms
2 = 10 ms
3 = 100 ms
4 = 1 s
5 = 1 min
6 = 1 h (Default)
7 = 1 d
ID1051 ResetOnTimeTripCounter
Reset Power on trip counter, rising edge will
reset counter.
BOOL value. WRITE access.
Write INT value 1 to reset if Process Data
is used.
3.2.7.2 Energy meter counter monitoring
ID11 EnergyMeter
Read ID80 and ID81 to see used format.
UINT value. READ only access.
ID82 EnergyMeterFormat
Decimal point place in the value
60 = 6 max number of digits, 0 fractional digits
61 = 6 max number of digits, 1 fractional digits
62 = 6 max number of digits, 2 fractional digits
UINT value. READ only access.
otee:
N
Most of the standard applications use ID number
ID80 for this variable.
ID81 EnergyMeterUnit
Unit for the energy meter
USINT value. READ only access.
1 = kWh
2 = MWh
3 = GWh
4 = TWh
