M220: Drive Overload
If the output current exceeds the unit's rated current, the display value counts up from 0%.In the
normal-duty mode (Normal-duty, A401 = 5/6/7/8), the display counts up at rate of 120%/minute in
respect to the unit's rated current. In the heavy-duty mode (Heavy-duty, A401 = 1/2/3/4), the display
counts up at a rate of 150%/minute.
When this display value reaches 100%, a fault "Drive Over Load" occurs.
Note: The unit rated current value differs for normal-duty mode and heavy-duty mode.
M221: Motor Overload
If the output current exceeds the motor overload reference, the display counts up from 0%.
When this display value reaches 100%, a fault "Motor
Over Load" occurs.

M301: Total Conductivity Time (Hrs)
The total (cumulative) power on time after product shipment is counted and displayed in this
parameter.
M302: Total Run Time (Hrs)
The total (cumulative) AC DRIVE run time after product shipment is counted and displayed in this
parameter.
M303: Automatic Tuning display
This parameter displays the progress of auto tuning process, when auto-tuning function is executed. It
will start with 0% and reach to 100% when auto-tuning is over. It will show zero otherwise.
M304: Rated Current (A)
This parameter displays the rated current capacity of the unit.
M305: Inverter Type (kW)
This parameter displays the rated kW capacity of the unit.
M306: Control Version
This parameter displays the ROM version of DSP Control Board (PCA-2014A) of AC DRIVE.
M307: Programmable Sequence Inputs
This parameter displays the status of various programmable sequence inputs.
M o d e - M G r o u p - 3

As shown above, line-2 shows the programmable sequence input and line-3 shows the status of
respective input. The zero value indicates that the programmable sequence input is OFF and 1
indicates ON. In the above screen, only PSI-2 is ON and the others are OFF.
