Chapter 6 - Parameter Description [APP]
6-69
Aux motor starting condition and output
(Pressure, air volume..) adjustment
Inverter turns Aux motors ON automatically when it
is impossible for a main motor to control increased
load, causing shortage in flow rate or flow pressure.
Maximum 4 Aux motors can be used. To turn on the
4 Aux motors automatically, starting frequency for
each motor should be set. (7 motors available with
option board).
Aux motor active condition: Main motor speed
exceeds Aux motor starting frequency (APP-44~50),
for the time over APP-58[Aux motor starting delay
time], Difference between PID reference and
Feedback value exceeds APP-71 [Starting Aux motor
pressure difference].
APP-44~50: Frequency to turn Aux motor ON. It
is set the same as main motor frequency
outputting equally when aux motor is turned ON.
APP-58: It should be set greater than system delay
time.
APP-71: It is set by comparing the pressure
difference when Aux motor is turned ON and that
of Aux motor starting frequency.
APP-61: This is the time inverter frequency is
decreased after Aux motor is turned ON. It should
be set higher than System delay time but it causes
Aux motor ON state to become too long.
Aux motor stopping condition and output
(Pressure, air volume..) adjustment
Inverter turns off the Aux motors when flow rate or
flow pressure is too large due to decreased load. For
Inverter to turn off Max 4 Aux motors automatically,
4 stopping frequency should be set separately. (7
motors available with Option board)
Aux motors are opened when main motor rotates
below APP-51~57 [Aux motor stopping frequency]
for the time over APP-59 [Aux motor stopping delay
time] and pressure difference between PID reference
and Feedback value exceeds the set value in APP-
71[Aux motor starting /stopping pressure difference].
APP-51~57: The Aux motors are turned off at this
frequency. It is set as dF, whose output matches
when Aux motor is off.
(dF = Aux motor On Freq – Aux motor Off Freq)
APP-59: It should be set higher than System Delay
Time.
APP-60: This is the time inverter frequency is
increased after Aux motor is turned OFF. It
should be set higher than System delay time but it
causes Aux motor OFF state to become too long.
