Setting range of Ap, Al, and Am
The 16-bit mode and 32-bit mode are provided for each Ap, Al, and Am, and they can be switched by setting a value in [Pr.62]
Electronic gear selection. When the resolution of the servo amplifier is high, values of Ap and Al can be set without reducing
the values by using an electronic gear with 32 bits.
Determined setting ranges are available for Ap, Al, and Am. The following table shows the setting ranges.
For details on the settings, refer to the following.

Page 380 [Pr.1] Unit setting

Page 381 [Pr.2] No. of pulses per rotation (16 bits) (Ap)

Page 382 [Pr.3] Movement amount per rotation (16 bits) (Al)

Page 387 [Pr.2] No. of pulses per rotation (32 bits) (Ap)

Page 388 [Pr.3] Movement amount per rotation (32 bits) (Al)
In addition, use the value set in [Pr.3] Movement amount per rotation as the movement amount per rotation (Al) to calculate
the movement amount per pulse (A).

If the value is beyond the setting range, setting values of each parameter can be decreased by reducing the numerator and
denominator with the movement amount per pulse (A) kept.
