ƒ C0025 = 110, 111, 112 or 113. The number of increments (512, 1024,
2048 or 4096) is set automatically.
The incremental encoder is supplied with voltage by the drive controller.

Stop!
If the supply voltage is too high, it may destroy the incremental
encoder.
Under C0421 you can adjust the supply voltage V
CC
(5 V) of the incremental
encoder in order to compensate for the voltage drop along the incremental
encoder cable (if required).

6.6.3 SinCos encoder at X8
SinCos encoders can be operated at X8. For the wiring diagram and the pin
assignment of X8, please refer to chapter "Wiring of the standard device"
® "Wiring of the feedback system".

Stop!
Uncontrolled acceleration of the motor!
ƒ If the SinCos encoder fails, the motor may accelerate in an
uncontrolled manner.
Protective measures:
ƒ Activate the monitoring for the SinCos encoder with
C0580 = 0.
ƒ SinCos encoder with 5 V supply voltage:
C0025 = 210, 211, 212, or 213. The number of increments (512, 1024,
2048 or 4096) is set automatically.
ƒ Single−turn SinCos encoder with 8 V supply voltage:
C0025 = 309, 310, or 311. The number of increments (128, 512 or 1024)
is set automatically.
ƒ Multi−turn SinCos encoder with 8 V supply voltage:
C0025 = 409, 410, or 411. The number of increments (128, 512 or 1024)
is set automatically.
ƒ Monitoring (SD8) of the SinCos encoder:
C0580 = 0 (TRIP, Lenze setting)
C0580 = 3 (off)
