Application Settings
Parameters are set as required in advanced programming mode (i.e., with the ADV indicator lit on the Digital
Operator). All the parameters that can be set in quick programming mode can also be displayed and set in
advanced programming mode.
Setting Examples
The following are examples of settings for applications.
•
To increase the speed of a 50 Hz motor by 10%, set E1-04 to 55.0 Hz.
•
To use a 0 to 10-V analog signal for a 50 Hz motor for variable-speed operation between 0 and 45 Hz (0%
to 90% speed deduction), set H3-02 to 90.0%.
•
To control speed between 20% and 80% to ensure smooth gear operation and limit the maximum speed of
the machine, set d2-01 to 80.0% and set d2-02 to 20.0%.
No-load Operation
This section describes trial operation in which the motor is in no-load state, that means the machine is not con-
nected to the motor. To avoid failures caused due to the wiring of the control circuit it’s recommended to use
the LOCAL mode. Press the LOCAL/REMOTE Key on the Digital Operator to change to LOCAL mode (the
SEQ and REF indicators on the Digital Operator should be OFF).
Always confirm safety around the motor and machine before starting Inverter operation from the Digital
Operator. Confirm that the motor works normally and that no errors are displayed at the Inverter. For applica-
tions, at which the machine only can be driven in one direction, check the motor rotation direction.
Jog Frequency Reference (d1-17, default: 6.00 Hz) can be started and stopped by pressing and releasing the
JOG Key on the Digital Operator. If the external sequence prevent operation from the Digital Operator, con-
firm that emergency stop circuits and machine safety mechanisms are functioning and then start operation in
REMOTE mode (i.e., with a signal from the control signal terminals). The safety precautions must always be
taken before starting the Inverter with the motor connected to the machine.
Both a RUN command (forward or reverse) and a frequency reference (or multi-step speed command) must
be provided to start Inverter operation.
Input these commands and reference regardless of the operation method (i.e., LOCAL of REMOTE).
