(33) Speed search 2 (03-0X =34)
(34) Switching between motor 1 and motor 2 (03-0X =40)
(35) Fire mode (03-0X=47)
When input is active (03-00~03-05=47) disables all inverter warning and hardware protections.
This function is commonly used in commercial applications where the inverter controls an
exhaust fan and needs run to destruction in case of a fire.
(36) KEB acceleration (03-0X=48)
When input is active enables KEB (Kinetic Energy Braking) during acceleration. Refer to the
parameter description of 11-47 and 11-48. Note: To enable set parameter 11-47 to a value
greater than 0.
(37) Forced Frequency Run (03-0X=57)
This function enables with the corresponding of parameter 23-28 and the source of frequency
command of parameter 00-05 set to the value of 5 (PID given, namely the parameter of 10-03
needs to be active.)
When any one of the multi-function digital input terminal (S1~S6) is set to the value of 16 (the
interdiction of PID function), pump will not depend on feedback to do any PID output
adjustment; simultaneously another one is set to the value of 57 (forced frequency run) and
inverter will have the frequency run setting depending on the parameter of 23-28. Inverter will
stop output when digital input terminals (S1~S6) are removed.
This function is applied to inverter output being controlled by external pressure sensor (eg.
differential pressure switch) when pressure sensor disconnects.
(38) Switch to Tolerance Range of Constant Pressure (03-0X=63)
When using in PUMP mode (23-00=1), the tolerance range of constant pressure (23-09) will be
used for walking up the inverter. When digital input terminal enables, the tolerance range of
constant pressure 2 (23-24) will be used.
(39) Short-circuit braking (03-0X=65)
To stop inverter by turning on Short-circuit braking with setting terminal. If executing run
command or jog command, short-circuit braking command will erased and start to run. The
following picture is short-circuit braking time process.
