Motor/Load Inertia Ratio
0 to 3
0
Setting 0: Below 1:10
The inertia ratio between the motor and the load is just less than 1:10.
Setting 1: Between 1:10 and 1:30
The inertia ratio between the motor and the load is between 1:10 and 1:30. Set n8-55 to 1 if a STo fault occurs as a result
of impact load or sudden acceleration/deceleration when n8-55 = 0.
Setting 2: Between 1:30 and 1:50
The inertia ratio between the motor and the load is between 1:30 and 1:50. Set n8-55 to 2 if a STo fault occurs as a result
of impact load or sudden acceleration/deceleration when n8-55 = 1.
Setting 3: Beyond 1:50
The inertia ratio between the motor and the load is higher than 1:50. Set n8-55 to 3 if a STo fault occurs as a result of
impact load or sudden acceleration/deceleration when n8-55 = 2.
n
n8-62: Output Voltage Limit (for PM OLV)
Sets the output voltage limit to prevent output voltage saturation. This value should not be set higher than the actual input
voltage.

n8-65: Speed Feedback Detection Control Gain during ov Suppression (for PM OLV)
Sets the gain for internal speed feedback detection control when overvoltage suppression is active. Although this setting
rarely needs to be changed, adjustment may be necessary under the following conditions:
• Increase this setting if motor oscillation or hunting occurs when ov suppression is active.
• Decrease this setting in increments of 0.05 to decrease the drive responsiveness during ov suppression.
