Pr. 80 "motor capacity"
Pr. Setting Range
0.5, 1.0, 1.5,
80
2.0, 3.5
Note: Changing the Pr. 71 or Pr. 80 changes the motor-specific control constants used in the drive
unit. Note that after changing the value, you need to make a reset.
Pr. 736 "overspeed adjustment factor"
Pr. Setting Range
736 0 to 100
The overspeed value depends on the load inertia, acceleration/deceleration time and load torque
(friction torque).
Using the acceleration torque (proportional to load inertia/acceleration/deceleration time) and load
torque (friction torque) to adjust the overspeed adjustment factor as outlined below allows
overspeed to be suppressed effectively.

Pr. 737 "maximum voltage braking ending time (s)"
Pr. Setting Range
737 0.0 to 60.0
Pr. 738 "stop time for operation reversion (s)"
Pr. Setting Range
738 0.0 to 60.0
Unit

Set the motor to be used.
Unit
Set the motor capacity.
kW
Set the same capacity as that of the drive unit.
Unit

Unit
Set the maximum voltage braking ending time when 9999 is set in
Pr. 11 [Section 8.5.4] "voltage braking operation time".
s Normally, the motor stops running within about 3s. When it is
rotated by external force, however, use this parameter to end
voltage braking forcibly.
Unit
Set the stop time for switch-over from forward rotation to reverse
s rotation or from reverse rotation to forward rotation. If you set 0,
there will be a stop time of at least about 100ms.
