i950 encoder module: Identification of modules with extension for TTL encoder

Question:

Extended encoder modules for i950 servo inverters with additional function for evaluating TTL encoders (delivery since January 2020).

How can the modules extended for TTL encoders be identified?

Answer:

Encoder modules with extension for TTL encoders can be recognised as follows:

Serial number of the encoder module starts with:
new: '1358 1387' and larger (additionally with TTL encoder evaluation)
before: '1354 4852' and smaller (only 'SinCos / Hiperface / SSI)
Hardware version 1A or higher,
Display parameter:
0x2002:15 Device module: HW version Encoder 1 (for shaft left)
0x2002:18 Device module: HW version Encoder 2 (for shaft right)
Text on front label with nameplate data:
'SinCos / Hiperface / SSI / TTL' (encoder module supplied individually packaged, for application by the customer).
'SinCos / Hiperface / SSI' (encoder module applied to the unit by Lenze)
