SINAMICS mode

Function description

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

The actual position values of the leading encoder are interconnected to the Terminal Module 41

via a connector input (p4420). The interconnection is possible for any encoder. This is true no

matter which drive object the encoder is assigned to. 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.

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.
