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.
■ 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.
■ n8-63/ n8-68: Output Voltage Limit Gain 1/2
n8-63 determines the gain level applied to the input voltage set in units of 0.01.
n8-68 determines a second gain level applied to the input voltage.
These parameters rarely need to be changed.
Note: These parameters are valid form the software versions 6002 or later.
■
n8-65: Speed Feedback Detection Control Gain during ov Suppression (OLV/PM)
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.
■ n8-74: Id No Load Start (for PM OLV)
Sets Id current level 1 for light loads.
Note: 1. This parameter is valid from software version 6002 or later.
2. An Operator Programming Error (oPE) occurs if the setting value deviates from the following condition: n8-74
≤
n8-75
≤
n8-50.
■ n8-75: Id No Load End (for PM OLV)
Sets Id current level 2 for light loads.
Note: 1. This parameter is valid from software version 6002 or later.
2. An Operator Programming Error (oPE) occurs if the setting value deviates from the following condition: n8-74
≤
n8-75
≤
n8-50.
