If the generator oscillates around the setpoint during an active phase or if it’s hard to reach the setpoint, it
means that the dead band [E1598] is bad adjusted:
 Decrease dead band [E1598] to improve the accuracy around the setpoint.
 Increase dead band [E1598] if the generator oscillates in frequency or in load.
If the generator takes too much time to reach the nominal speed during the regulation, it means that
period [E1874] is too long.
If you don’t get the desired compensation, check the following points:
 Is the potentiometer still running when GENSYS 2.0 sand an output signal? Est-ce que le
potentiomètre tourne toujours si GENSYS 2.0 envoie un signal de sortie?
 Otherwise, the potentiometer doesn’t control a wide enough speed range .
Note: If a pulse generates an over-compensation, the motor potentiometer still running even if there is no
pulse. A shunt resistor on the motor input can correct this problem.
2/ Frequency center settings
If the generator changes his speed but compensated too much or not enough to reach the nominal speed,
the pulse [E1873] is bad adjusted:
 Decrease [E1873] to reduce the center frequency control
 Increase [E1600] to increase the center frequency control
Note : If an automatic center frequency control exist, (e.g isochronous mode), the parameter [E1873] can be
set to 0.
