HVAC Drive H300 165
Issue Number: 3
When this parameter is set to OFF (0) the integrator operates normally.
Setting this parameter to On (1) will cause the integrator value to be
held. Setting this parameter does not prevent the integrator from being
reset to zero if the PID controller is disabled.
If PID is used to control the motor output via Menu 1 and sleep mode is
enabled, then the drive will automatically stop the motor when the output
drops below the sleep/wake threshold. The feedback may then fall
causing the output and hence the feedback to rise again. Setting
Pr 14.028 and Pr 14.029 to non zero values results in the value in
Pr 14.028 being added to the PID reference for a length of time defined
in Pr 14.029 when the drive attempts to enter sleep mode.. This will
reduce the frequency of the transitions into sleep mode. Pr 14.030
indicates when the boost system is enabled.
