You can use the machine resonance
speed to make this setting to reduce the
1 0 0 to 60 response level of the machine resonance
frequency band, avoiding machine
resonance.

You can make setting to output a signal if
0.1% 150% 0 to 400% the motor torque exceeds the
predetermined value.
Frequency is limited at the set frequency +
0.01Hz 20Hz 0 to 120Hz
Pr.873 during vector control.
At occurrence of any alarm, output is shut
0 off immediately. At this time, the alarm
output also turns on.
At occurrence of external thermal operation
(OHT), electronic thermal relay function
(THM) or PTC thermistor function (PTC)

alarm, the motor is decelerated to a stop
1 and output is shut off.
At occurrence of an alarm other than OHT,
THM and PTC, output is shut off
immediately. Same operation as when "0" is
set is performed under position control.
