9.8.12 Connection and parameters of the position sensing system
Commissioning step:
Set the parameters of the position sensing system:
Follow function diagram [815] in order to connect the technology with
the position sensing system for the motor encoder [330] or an external
machine encoder [335]. On this sheet, you will find two columns for
each type of position sensing with the parameter settings (one for the
control signals and one for the evaluation signals). In the factory
setting, the motor encoder is prewired to a large extent. If you use the
motor encoder − this is normally the case − you only need to change
the following parameter settings:
; Position sensing for motor encoder in slot C [330]:
------------------------------------------------------
; Connect to technology [330] <==> [815] [836]:
U535=120 P172=302
U539=122 P174=301
P184=303
; Additional connections usually required for synchronization
; [330] ==> [836.4] (not required for positioning!)
U665=122 ; Meas. pos. for pos. correction [330] ==> [836.4]
U671=120 ; Use actual position as initial set value
; for slave path setpoint
; Configuration for incremental encoder (resolver, ERN encoder...):
P183=xx01 ; No homing (e.g. for
; roll feed or synchronization)
P183=xx11 ; Home position to right of rough pulse/ BERO
; (see also MD5 and [821])
P183=xx21 ; Home position to left of rough pulse/ BERO
; Configuration for absolute encoder:
P183=xxx2 ;[330]
U950.19=3 ; Nest encoder detection in sampling time [260.8]
; If not standard encoder: set parameters as
; described in "Multiturn encoder evaluation"
