Explanation
Display
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.

displayed.
The detailed running status data of the last four trips are also saved
and displayed.
Protection
Refer to Section 8.6 "Protective Functions."
Environment
Refer to the Chapter 2, Section 2.1 "Operating Environment" and Chapter 1, Section 1.4,
"Storage Environment."
