3.2.37 Command: RS - Resolver Shaft
Function:
it informs about the phase shift between motor and resolver.
Syntax:
data monitoring:

1 RS <CR>: the answer for axis 1 will be: "A1 RESOLVER SHAFT BIT = XXXXX". Where, if the
autophasing has been correctly made:
XXXXX = 14000 to 16000 for 6 pole motor and resolver or 8 pole motor and resolver
XXXXX = approx. 17000 or approx. 39000 or approx. 61000 for 2 pole resolver and 6 or
8 pole motor.
3.2.38 Command: RX - Maximum of R/D resolution
Function:
it allows to set the maximum of Resolver to Digital converter
resolution. The R/D resolution will automatically be switched
according to actual speed for optimum system performance
between RN (minimum) and RX (maximum).
The default is 16 bit.
If acceleration [rad/s
2
] > 314000/NP, then RX must be set to 14.
If RX equals RN, the R/D resolution is fixed.

Range:
10, 12, 14 and 16 (it must be

2 RX <CR>: questions axis 2 about the maximum resolution of R/D. The answer is: "A02 MAXIMAL R/D
RES. = 16" (if 16 bit R/D resolution has been set for axis 2).
