Item Explanation
During running/stop
Speed monitor, output current (A), output voltage (V), input power (kW), PID
command value, PID feedback value, PID output, timer (s) and input watt-hour
(kWh).
Select the speed monitor to be displayed from the following:
Output frequency (before slip compensation) (Hz), output frequency (after slip
compensation) (Hz), reference frequency (Hz), load shaft speed (min
-1
), line
speed (m/min), constant feeding rate time (min).
* Speed monitor can display the speed specified with E48.
Life early warning
The life early warning of the main circuit capacitors, capacitors on the PC boards
and the cooling fan can be displayed.
Cumulative run hours
The cumulative motor running hours, cumulative inverter running hours and
cumulative watt-hours can be displayed.
I/O checking Indicate the status of the Di, Do on the control circuit.
Energy saving monitor Input power, Input power × coefficient are indicated.

Display
During running or when
tripped
Trip history: The causes (codes) of the last four trips are saved and displayed.
The detailed running status data of the last four trips are also saved and displayed.
Protection
Refer to Section 8.8 "Details of Protective Functions."
