Option terminals
SinCos, SinCosHiperface, EnDat, SSI encoder interface cards (ATV ... 383)
Encoder interface cards with RS422 compatible differential outputs with encoder emulation (ATV ... 383)
This encoder card has two groups of parameter switches:
• The first is for selecting the supply voltage supplied by the interface card to the encoder: 5 V or 15 V.
• The second is a set of five switches numbered 1 to 5 (see diagram below). The division ratio for the ESIM outputs is selected using
switches 1, 2 and 3. Switches 4 and 5 are used to select the input signals for the encoder card. Fault detection will be inhibited for
the
inputs selected using these switches.
Selecting the encoder
The encoder interface cards available as options with the ATV71 enable the use of different encoder technologies (incremental ou absolute).
• Incremental encoder with differential outputs compatible with the RS422 standard
• Incremental encoder with open collector outputs
• Incremental encoder with push-pull outputs
• Incremental encoder with RS422-compatible differential outputs with encoder emulation
• Resolver absolute encoder
• SinCos incremental, SinCosHiperface absolute, EnDat absolute, SSI absolute encoders
The VW3 A3 408, VW3 A3 409 and VW3 A3 411 encoder cards available as an option with the ATV71 specification 383 can be used with
a synchronous or asynchronous motor for closed-loop control.
