0
Encoder
Forward rotation is clockwise rotation
when viewed from A.
1
Encoder
(Factory setting)
Forward rotation is counterclockwise rotation
when viewed from A.
Set the excitation ratio under no load.
0 to 100%
Use for utilization of the tuning data or direct input.
You can use the mechanical resonance speed to make this setting to reduce the
response level of the mechanical resonance frequency band, avoiding mechanical
resonance.
0 to 31
Set the depth at which the gain of the mechanical resonance frequency set in Pr. 862 is
lowered.
0 to 3
You can make setting to output a signal if the motor torque exceeds the predetermined
value.
0 to 400%
You can make setting to output a signal if the speed has fallen to or below the preset
low speed.
0 to 3600r/min
Set the reference for the motor torque or load meter torque monitoring output (DA1 or
other analog output).
0 to 400%
Set the primary delay filter for the DA1 analog output.
0 to 5s
You can change the setting of the multi-function analog terminal (terminal 1).

9999 No function
If the difference between speed command value and speed exceeds the setting of the
speed deviation level (Pr. 870) for longer than the setting of the speed deviation time
(Pr. 871), speed deviation excessive "E.OSD" is displayed and the motor stops.
0 to 1500r/min, 9999
CAUTION
Use this function when a difference in speed will constitute a hindrance. It is
independent of torque control.
0 to 100s
0 to 3600r/min
Set the load level of the motor at which OLT alarm.
0 to 200%
You can classify faults into a minor fault and major faults according to the alarms, and
make setting to select between immediate output shutoff and output shutoff after
deceleration to stop.
0: Immediate output shutoff
1: Output shutoff after deceleration to stop (Immediate output shutoff other than OHT
and THM)
When using the motor provided with encoder, you can input the contact signal of a
thermal relay etc. to terminal OH to provide motor protection against overheat.
0: None
1: Thermal relay input available
