Parameterization of the TTL encoder

Interface configuration of encoder for loop control

By way of P 0520, P 0521, P 0522 the physical encoder interface is adapted to the
current, speed or position controller.

Parameters

P. no.	Parameter Setting	Function
P 0520	ENC_MCon Encoder	Selection of encoder channel for commutation angle and current control. Feedback signal for field-oriented regulation.
P 0521	ENC_SCon Encoder	Selection of encoder channel for speed configuration. Feedback signal for speed controller
P 0522	ENC_PCon Encoder	Selection of encoder channel for position information. Feedback signal for position controller
Parameter settings apply to P 0520, P 0521, P 0522
(0)	Off
(1)	CH1
(2)	CH2
(3)	CH3

Configuration of TTL encoder simulation and repeater mode

The TTL module can simulate a TTL encoder with the aid of encoder simulation. In this, the encoder simulation forms incremental encoder-compatible pulses from the position of the rotary encoder connected to the motor. Two 90° offset signals are generated on tracks A and B as well as a zero pulse (track R). The pulses per revolution of the encoder simulation can be set over a range from 0 to 65535 by way of P 2621.
In repeater mode (only TTL signals can be evaluated) the TTL signal connected to X7 or X8 is outputted by way of encoder simulation. The transmission is isolated. The signal delay of the repeater function is < 2 µs.
