8.3.1.1 Transmitter systems for direct drives
The Feedback option F12 makes it possible to operate linear motors as well as
torque motors. Compax3 supports the following transmitter systems:
Special encoder systems for direct
drives
Option F12
Analog hall sensors
!
Sine - cosine signal (max. 5Vss
1
; typical
1Vss) 90° offset
!
U-V Signal (max. 5Vss
2
; typical 1Vss)
120° offset.
Encoder
(linear or rotatory)
!
Sine-cosine (max. 5Vss
3
; typical 1Vss)
(max. 400kHz) or
!
TTL (RS422) (max. 5MHz)
with the following modes of commutation:
!
automatic commutation (see on page
108) or
!
Digital hall sensors
Distance coded
feedback systems
!
Distance coding with 1VSS - Interface
!
Distance coding with RS422 - Interface
(Encoder)
The motor performs automatic commutation after:
!
Power on,
!
A configuration download or
!
An IEC program download
The time duration (typically 5-10 sec) of automatic commutation can be optimized
with the start current (see in the optimization display of the C3 ServoManager;

2
Max. differential input between SIN- (X13/7) and SIN+ (X13/8).
3
Max. differential input between SIN- (X13/7) and SIN+ (X13/8).
