* 7. The default depends on the MxC capacity. The values for a 200 V class MxC for 5.5 kW are given.
* 8. The setting range depends on the MxC capacity. The value for a 200 V class MxC for 5.5 kW is given.
* 9. Set T1-02 and T1-04 when 2 is set for T1-01. Only set value 2 is possible for V/f control.
* 10.The setting range is from 10% to 200% of the MxC rated output current. The value for a 200 V class MxC for 5.5 kW is given.
* 11. For induction motors with two, four, or six poles.
‹ Application Settings
Parameters are set as required in Advanced Programming Mode (“ADV” will be displayed on the LCD
screen). 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 prevent the machine from being operated in reverse, set b1-04 to 1 to disable reverse operation.
• To increase the speed of a 60 Hz motor by 10%, set E1-04 to 66.0 Hz.
• To use a 0 V 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 being no-load operation (without connecting the machine and 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).
Always confirm safety around the motor and connected machinery before starting MxC operation from the
digital operator. Confirm that the motor works normally and that no errors are displayed.
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 prevents operation from the digital operator, confirm
that emergency stop circuits and machine safety mechanisms are functioning, and then start running the motor
in Remote Mode (i.e., with a signal from the control signal terminals). The safety precautions must always be
taken before starting the MxC with the motor connected to the machine.
‹ 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.
INFO
Both a Run Command (forward or reverse) and a frequency reference (or multi-step speed reference) must
be provided to start MxC operation.
Input these commands and reference regardless of the operation method (i.e., LOCAL or REMOTE).
