ECON-4 1.4.0 Global Guide

Load ctrl: SpeedReqRPM
IMPORTANT: Configuration of Analog output AOUT2 from IS2GASXX to ECON-4 has to be
configured as SpeedReqRPMx8
Controller setting in case ECON4 is set to communicate with controller via CAN1 (Speed request set to DATA
mode)
Besides the above mentioned inputs/outputs adjustment, the IGS-NT setpoints shall be adjusted in the
following way:
Sync/Load ctrl: SpeedGov Bias = 0 Volts
Sync/Load ctrl: SpeedGovLoLim = -10 Volts
Sync/Load ctrl: SpeedGovHiLim = 10 Volts
Sync/Load ctrl: Freq gain = 5 %
Sync/Load ctrl: Freq int = 5 %
Sync/Load ctrl: Angle gain = 10 %
IMPORTANT: Please, take in account, there are several setpoints of ECON-4, which are not
accessible via IGS-NT control unit in case of DATA mode. These parameters are crucial for ECON-4
and used Actuator adjustment and so these are accessible via ECON-4 connection ONLY. Use
ComAp PC sw WinScope to adjust these setpoints.
For all modes of ECON-4 usage adjust
Type of used Actuator – Main PID: Actuator type, PWM rate. The ACT1-4 are preadjusted, see: Act type 1 –
predefined for Woodward ITB 0-200mA, PWM rate [Hz].Speed PID loop – MAIN PID: Speed gain = 10%,
Speed Int = 10%, Speed der = 40%Type of ECON-4 communication mode: Engine RPM: Speed RequestIdle,
Nominal, Overspeed RPM: Engine RPM: Idle RPM, Nominal RPM, Overspeed.
