No-Load Operation; Loaded Operation - Omron SYSDRIVE RV Series User Manual

To use a 0 to 10-V analog signal for a 60 Hz motor for variable-speed operation between 0 and 54 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

To start no-load operation (without connecting the machine to the motor), 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).
The motor and the machine must be checked for safety before starting Inverter operation from the Digital
Operator. Confirm that the motor works normally and that no errors are displayed at the Inverter.
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.
INFO

Loaded Operation

Connect the machine to the motor and then start operation as described for no-load operation (i.e., from the
Digital Operator or by using control circuit terminal signals).
Connecting the Load
After confirming that the motor has stopped completely, connect the mechanical system.
•
Be sure to tighten all the screws when securing the motor shaft to the mechanical system.
•
Operation Using the Digital Operator
Use the Digital Operator to start operation in LOCAL mode in the same way as in no-load operation.
•
Make sure the STOP Key on the Digital Operator is easily accessible so that any unexpected movement
•
can be stopped.
At first, set the frequency reference to a low speed of one tenth the normal operating speed.
•
Checking Operating Status
Having checked that the operating direction is correct and that the machine is operating smoothly at slow
•
speed, increase the frequency reference.
After changing the frequency reference or the rotation direction, check that there is no oscillation or abnor-
•
mal sound from the motor. Check the monitor display to ensure that U1-03 (Output Current) is not too
high.

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).
