Address:21184 ( 52C0 hex )
Format: 16 bit unsigned
Note: Linear Scaling ( 1 =
0.006104 % ) iERS Rate
Determines the rate at which the
load is regulated during the iERS
energy saving mode
During periods of instability the
"Current Irms" and "True Power
Factor" will oscillate rapidly.
Increase if the applications shows
signs of instability.
Reduce to increase the speed of
response
0 ( 0 hex ) 0
16384 ( 4000 hex ) 100
4096 ( 1000 hex ) 25
% R/W
Address:21320 ( 5348 hex )
Format: 16 bit unsigned
Note: Linear Scaling ( 1 =
0.006104 % ) Start Saving Level
The current in Amps at which the
iERS is enabled or disabled.
The iERS function is active when
the motor current is less than the
"Start Saving Level"
When the iERS function is disabled
internal bypass relays close to
improve efficiency.
8192 ( 2000 hex ) 50% I-motor

Address:21376 ( 5380 hex )
Format: 16 bit unsigned
Note: Linear Scaling ( 1 =
0.006104 % ) iERS Level
Determines the maximum energy
saving potential.
Reduce if the application shows
signs of instability.
The amount of energy that can be
saved may fall as the "iERS level"
is reduced.

Note: Linear Scaling (1 = 1° of
mains cycle)
Time(ms)=(Value/PNU32000)*(25
/9) Ref PF Degrees
The Reference Power Factor used
by the iERS saving function
This is the target Power Factor for
the iERS saving function.
The parameter will change
dynamically dependant on motor
operation
The parameter displays the
displacement part of the True
Power Factor and is used for
diagnostic purposes.

Note: Linear Scaling (1 = 1° of
mains cycle)
Time(ms)=(Value/PNU32000)*(25
/9) Pres PF Degrees
The Present Power Factor used by
the iERS saving function
This is the actual Power Factor for
the iERS saving function.
The "Delay" is constantly adjusted
to minimise the control loop error
between "Pres PF Degrees" and
"Ref PF Degrees"
The parameter displays the
displacement part of the True
Power Factor and is used for
diagnostic purposes.
