5 Learning Advanced Features
This chapter describes the advanced features of the H100 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.144
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.149
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.151
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.152
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.153
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.155
Slip compensation This feature ensures that the motor rotates at a constant speed,
by compensating for the motor slip as a load increases.
p.158
PID control
PID control provides constant automated control of flow,
pressure, and temperature by adjusting the output frequency of
the inverter.
p.159
Sleep-wakeup
operation
When the inverter operation continues below the PID
conditions for a set time period, the PID reference is
automatically raised to extend the operation standby time. This
keeps the inverter in a standby (sleep) mode when the demand
is very low.
p.175
Auto-tuning
Used to automatically measure the motor control parameters to
optimize the inverter‘s control mode performance.
