Note:
When the setting value is increased, a speed search of a motor rotating at a high frequency can be performed. However, if the setting
value is too high, the calculated speed will oscillate and a restart will fail. In such cases reduce the setting value.

Note:
• The value set in n8-51 [Accel / Decel Pull-In Current] is enabled with speeds that do not exceed the value set in n7-10. The value set in
b8-01 [Energy Saving Control Selection] is enabled with speeds higher than the value set in n7-10.
• If a significant amount of oscillation occurs when running at low-speeds, increase the setting value.
• Reduce the setting value when priority is to be placed on energy-saving measures in the low speed range.

Note:
• With the settings n7-17 = 1, 2, there could be some delay before startup because of the adjustment time.
• With the settings n7-17 = 1, 2, the line-to-line resistance value of E9-10 [Motor Line-to-Line Resistance] may be set.
• Set n7-17 = 2 if the temperature state is likely to change at startup.
• To shorten the startup time, set n7-17 = 0, then perform line-to-line resistance tuning.
• If startup from the coasting state can be expected, set n7-17 = 0, then perform line-to-line resistance tuning.

Sets, as a percentage, the Initial Rotor Position Estimated Current, taking
the E5-03 [Motor Rated Current (FLA)] as the 100% value. Normally there
is no need to change this setting.
