IDNP3011 (35 779) Encoder Emulation Configuration
Sets the signaling format for the encoder emulation on connector X5. A new emulation
mode will not become active until the parameter set is saved to non-volatile memory and
a coldstart or warmstart (IDN128) procedure is initiated.

Input
The interface is used as an input.
1
AqB (ROD)
Incremental encoder emulation. Incremental encoder compatible
pulses (max. 250 kHz) are transmitted as two signals (A and B)
with a 90° electrical phase difference (quadrature). A zero marker
pulse is also transmitted. If an encoder with a commutation track is
used, then the output of the zero marker pulse is inhibited until the
zero pulse from the encoder has been evaluated.
2
SSI
Synchron serial interface (SSI) for absolute encoder emulation. The
standard SSI absolute encoder format transmits 24 bits. The upper
12 bits are fixed to zero and the lower 12 bits contain position infor-
mation. For ‘N’ pole resolver feedback systems, the transmitted po-
sition refers to the position within 2/N turns of the motor. If an enco-
der with a commutation track is used as feedback, then the upper
12 bits are set to 1 (invalid data) until homing is performed.

IDNP3015 (35 783) Hardware Limit Switch Consequence
This parameter define the consequence of the Hardware Limit Switch, if the correspond-
ing digital inputs (IDNP3002 and/or P3003) are set to the function "hardware limit
switches".
If the IDNP3015 is set to 0, a warning occurs.
If the IDNP3015 is set to 1, a fault occurs, the amplifier ramps down and sets fault bit 15
in IDN11 and in IDN129 the bit 2.
After the reset class 1 diagnostic command (IDN99) the amplifier can enable again and
move back into the valid range. During the procedure amplifier-controlled homing
(IDN148), the hardware limit switch can be used in the normal way (refer to IDNP3027).
