5 Learning Advanced Features
This chapter describes the advanced features of the ”S” Series inverter. Check the reference page in
the table to see the detailed description for each of the advanced features.
Advanced Tasks Description Ref.
Auxiliary frequency
operation
Use the main and auxiliary frequencies in the predefined
formulas to create various operating conditions. Auxiliary
frequency operation is ideal for Draw Operation* as this
feature enables fine-tuning of operation speeds.
p.120
Jog operation
Jog operation is a manual operation. The inverter operates to
a set of parameter settings predefined for Jog operation
when the Jog command button is applied.
p.125
Up-down operation
Uses the upper and lower limit value switch output signals
(i.e. signals from a flow meter) as Acc/Dec commands to
motors.
p.128
3-wire operation
3-wire operation is used to latch an input signal. This
configuration is used to operate the inverter by a push
button.
p.129
Safety operation mode
This safety feature allows the inverter’s operation only after a
signal is input to the multi-function terminal designated for
the safety operation mode. This feature is useful when extra
care is needed in operating the inverter using the multi-
purpose terminals.
p.130
Dwell operation
Use this feature for the lift-type loads such as elevators, when
the torque needs to be maintained while the brakes are
applied or released.
p.132
Slip compensation
This feature ensures that the motor rotates at a constant
speed, by compensating for the motor slip as a load
increases.
p.133
PID control
PID control provides constant automated control of flow,
pressure, and temperature by adjusting the output frequency
of the inverter.
p.135
Auto-tuning
Used to automatically measure the motor control
parameters to optimize the inverter’s control mode
performance.
p.143
Sensorless vector control
An efficient mode to control magnetic flux and torque
without special sensors. Efficiency is achieved through the
high torque characteristics at low current when compared
with the V/F control mode.
p.146
Energy buffering operation
Used to maintain the DC link voltage for as long as possible
by controlling the inverter output frequency during power
interruptions, thus to delay a low voltage fault.
p.154
Energy saving operation Used to save energy by reducing the voltage supplied to
