CL Setting range Description
[Default]
Speed offset
(S6 Scania, EMS2 Volvo, EGS Woodward, Cummins)
The easYgen sends a speed offset with a range of 0 to 100 % (every 20 ms).
50 % = rated speed.
There is also an internal speed offset configured in the ECU, this parameter
determines what corresponds with 0 % or 100 %. If there is a positive and a
negative speed offset, they should be symmetrical in the ECU.
We recommend to have the same speed offset configured in the ECU and in
this parameter here. A different setting will result in an additional "controller
gain".
How to test this parameter during commissioning:
Isolated operation
Disable the frequency controller and change parameter
initial state between 0 and 100 %, the engine should change the speed as fol‐
lows:
n
n
n
Mains parallel operation
Check with the setpoint in the display if the engine is able to deliver the full
power.
Speed setpoint
(EMR2 Deutz, ADEC MTU, EGS Woodward, EEM SISU, Standard)
The easYgen sends a speed setpoint in rpm (every 10 ms) that varies around
the rated speed in the range of +/- the speed deviation.
How to test this parameter during commissioning:
Isolated operation
Disable the frequency controller and change parameter
initial state between 0 and 100 %, the engine should change the speed as fol‐
lows:
n
n
n
Mains parallel operation
Check with the setpoint in the display if the engine is able to deliver the full
power.
Keep this value as small as possible, i.e. do not enter a speed deviation of
500, if the engine varies only between 1,400 and 1,600 rpm.

0 = rated speed – negative speed offset from ECU
50 = rated speed
100 = rated speed + positive speed offset from ECU
0 = rated speed – speed deviation ECU
e.g.: 1,500 – 120 = 1,380 rpm
50 = rated speed
e.g.: = 1,500 rpm
100 = rated speed + speed deviation ECU
e.g.: 1,500 + 120 = 1,620 rpm
