7.12 Encoder Interface
Overview
The SINAMICS G115D inverter has a simple HTL encoder interface where the A and B tracks of
the HTL encoder are read into the inverter via two digital inputs (DI0 and DI1).
The other encoder signals, inverted A and B tracks and zero signals, are not read in or evaluated.
As an alternative to the HTL encoder, one sensor can be connected as a pulse encoder or two
sensors/signals as pulse/direction encoders.
An encoder or sensor connected to the SINAMICS G115D is not used for motor control.
The SINAMICS G115D inverter is only a decentralized encoder interface for a higher-level
controller (PLC).
This means that the encoder signal is acquired in the SINAMICS G115D and the counter value
can be sent to the control system via Pro󹪝net with telegram 3 in order to realize positioning
with a technology object.
When using an HTL encoder:
• An HTL encoder can be read in via DI0 and DI1 (A and B track only).
• 2-bit 󹪝ne resolution
• Pulse multiplication (fourfold)
When using sensors (pulse / direction interface):
• One sensor (pulse) or two sensors / signals (pulse and direction) can be connected
• 2-bit 󹪝ne resolution
• No pulse multiplication
Speci󹪝cations
Maximum resolution: 2048 pulses/rotation
Maximum HTL frequency: 200 KHz
Maximum permitted cable length for the Encoder: 30 m with shielding.
