n
n8-55: Load Inertia (OLV/PM)
Sets the ratio between motor inertia and the inertia of the connected machinery. If this value is set too low, the motor may not
start very smoothly and trigger an STo (Motor Step-Out) fault.
Increase this setting for large inertia loads or to improve speed control response. A high setting with low inertia load may
cause oscillation.
No.
n8-55
Setting 0: Below 1:10
The inertia ratio between the motor and the load is lower 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 an 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 an 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 an STo fault occurs as a result of impact
load or sudden acceleration/deceleration when n8-55 = 2.
n
n8-62: Output Voltage Limit
Sets the output voltage limit to prevent voltage saturation. Do not set this value higher than the actual input voltage.
No.
n8-62
<1> Values shown are specific to 200 V class drives. Double value for 400 V class drives.
n
n8-63: Output Voltage Limit Proportional Gain (for PM Motors)
Stabilizes constant output.
There is normally no need to change this parameter from the default value.
Note:
1. This parameter is only available in OLV/PM.
2. This parameter is available in drive software versions PRG: 6114 and later.

n8-64: Output Voltage Limit Integral Time (for PM Motors)
There is normally no need to change this parameter from the default value.
Note:
1. This parameter is only available in OLV/PM.
2. This parameter is available in drive software versions PRG: 6114 and later.
No.

n8-66: Output Voltage Limit Output Filter Time Constant (for PM Motors)
There is normally no need to change this parameter from the default value.
Note:
1. This parameter is only available in OLV/PM.
2. This parameter is available in drive software versions PRG: 6114 and later.
