7.5.14.2 Object 0x5869: Integrator preload gain
This parameter contains the integrator preload gain.
7.5.14.3 Object 0x586A: Integrator preload parameter
With this parameter every INT16 application parameter can be mapped as preload input. Per default the pres-
sure setpoint <PrsSetpoint> (0x6380) is mapped.
Value description
This pointer contains a combination of index, sub-index and length of the parameter to be used. It may only
refer to parameters with a bit length of 0x10.
The default value is 0x63800110, which refers to the <PrsSetpoint> (0x6380), sub-index 0x01 with a length of
16 bit (16=0x10).
7.5.14.4 Object 0x5860: Integrator preload values
This object contains two pre-calculated preload values.
These values can be mapped using the parameter <IntegratorPreloadParameter> (0x586A) to the integrator
preload input.
