8.2.5 Configuration parameters
Parameter P93: valid from next move command.
P93 ="1"
Positioning processes refer to real zero.
To set the reference, use the "Find machine zero" function (Input I1="1" and I2="1",
see Page 148) once the system is switched on.
Various machine zero modes are described from Page 80.
P93 ="2"
Positioning processes always refer to the relevant start position.
The "Find machine zero" function is not necessary but possible.
Set P1 (real zero) = 0.
To avoid inaccuracies during conversions, use the "Increments" measurement
units in continuous mode (see below).
Operation with absolute value sensors is not permitted when working in
continuous mode.
P93 ="4":
In this operating mode, the drive controller operates as a speed controller, the
position controller is switched off. The following applies:
♦ Commands not permitted: POSA, POSR, POSR SPEED, POSR OUTPUT, POSA
HOME, ACCEL-.
♦ The SPEED command contains a prefix for the direction of rotation.
♦ Output O3 is not assigned;
O5 has the "Programmed nominal speed reached" function (see Page 120).
♦ The data record indicator is set to N001 using "Approach real zero".
♦ The "Find machine zero" function (I1&I2) is not assigned.
Parameter P90
P90 ="1"
P90 ="2"
P90 = "0": Accurate increment operation without conversion inaccuracies.
This measuring unit is only useful when using the "General drive" drive type
and especially in continuous mode. The levels of accuracy are not increased
when working with other drive types.
The "Travel per motor revolution" (P83) is specified in increments.
Meaning: P83 = 2
n when n = 4, 5, 6, ...16
This corresponds to a resolution of 16 .... 65 536 increments per motor
revolution.
P83 influences the resolution and also the max. travel distance:
