<1> Default setting is determined by parameter o2-04, Drive Model Selection.
<2> Setting range value is dependent on parameter C1-10, Accel/Decel Time Setting Units. When C1-10 = 0 (units of 0.01 seconds), the setting range
becomes 0.00 to 600.00 seconds.
<3> Values shown are specific to 200 V class drives. Double the value for 400 V class drives.
