SINAMICS mode

The SINAMICS mode of the incremental encoder emulation is set using parameter p4400 =
1. The incremental encoder emulation is based on the encoder actual position value of the
leading encoder.
The actual position values of the leading encoder are interconnected to the Terminal Module
41 via a connector input (p4420). This is possible for every encoder, irrespective of the drive
object to which it is assigned. This means that the actual position values at the TM41 are
available as pulse encoder emulation - including the zero mark. The signals of the pulse
encoder emulation appear just like the signals of a TTL encoder - and can be processed by
an external controller or hardware.
Note
Connector input p4420 should be interconnected with signal source r0479 (diagnostics
encoder actual position value Gn_XACT1). The value is updated with each DRIVE-CLiQ
base cycle and displayed with the correct sign.
The TM41 supports a step-up/step-down ratio between the output signal of the leading
encoder and the output signal of the TM41. The number of encoder pulses per revolution of
the leading encoder is set using p4408. The pulse number of the TM41 encoder emulation is
set using p0408. The parameters p4408 and p0408 may have any relationship with each
other.
The zero mark signal for the TM41 is generated from the zero position of the leading
encoder. Parameters p0493, p0494 and p0495 of the drive/encoder object apply to the
generation of the zero position of the leading encoder.
