Description
Speed Request (page 256) is decreased / increased when the binary input is closed. Speed Down has
higher priority when both Up and Down inputs are active. RPM inc/dec rate is defined by BI Speed Ramp
(page 122).
Engine speed can be set by Logical Analog Input Requested RPM or by SPEED UP (PAGE 179) and SPEED
DOWN (PAGE 178).
Following Speed Request initialization is valid when REQUESTED RPM (PAGE 236) is not configured.
Speed Request (Idle) = 0.0%. Inputs are active in LOC (Local) mode.
Speed Request (Running) = 50.0% for AUX (ECU 50% = Nominal RPM).
Speed Request (Running) = 0.0% for PRP.
See Engine Values: (page 257) (page 257) and (page 257) (page 257) modes.
The Binary inputs SpeedUp and SpeedDown ramp
function is for the 0.6 sec constant 0.4%/s and does not
depend on BI Speed Ramp (page 122) setting. This
function enables fine setting of Engine speed to specific
like 1500RPM value.
Dual rate ramp
Note: Minimal Speed Up and Speed Down pulse duration is 110ms to be accepted by controller.
