5 Learning Advanced Features
This chapter describes the advanced features of the G100 inverter. Check the
reference page in the table to see the detailed description for each of the application
features.
Advanced Tasks Use Example 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.109
Jog operation
Jog operation is a kind of a manual operation. The inverter
operates to a set of parameter settings predefined for Jog
operation, while the Jog command button is pressed.
p.113
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.115
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.117
Safe 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.119
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.120
Slip compensation
This feature ensures that the motor rotates at a constant
speed, by compensating for the motor slip as a load
increases.
p.122
PID Control
PID control provides automat
ic control of the inverter’s
output frequency for the purpose of constant automated
control of flow, pressure, and temperature. p.123
Auto tuning
Used to automatically measure the motor control
parameters to optimize the inverter’s control mode
performance.
p.131
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.134
Energy buffering
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 trip.
p.140
Energy saving Used to save energy by reducing the voltage supplied to p.144
