Parameters and firmware blocks
255
Group 90 ENC MODULE SEL
Settings for encoder activation, emulation, TTL echo, and encoder cable fault
detection.
The firmware supports two encoders, encoder 1 and 2 (but only one FEN-21
Resolver Interface Module). Revolution counting is only supported for encoder 1.
The following optional interface modules are available:
• TTL Encoder Interface Module FEN-01: two TTL inputs, TTL output (for encoder
emulation and echo), two digital inputs for position latching, PTC temperature
sensor connection
• Absolute Encoder Interface FEN-11: absolute encoder input, TTL input, TTL
output (for encoder emulation and echo), two digital inputs for position latching,
PTC/KTY temperature sensor connection
• Resolver Interface Module FEN-21: resolver input, TTL input, TTL output (for
encoder emulation echo), two digital inputs for position latching, PTC/KTY
temperature sensor connection
• HTL Encoder Interface Module FEN-31: HTL encoder input, TTL output (for
encoder emulation and echo), two digital inputs for position latching, PTC/KTY
temperature sensor connection.
The interface module is connected to drive option Slot 1 or 2. Note: Two encoder
interface modules of the same type are not allowed.
For encoder/resolver configuration, see parameter groups 91 (page 260), 92 (page
266) and 93 (page 267).
Note: Configuration data is written into the logic registers of the interface module
once after the power-up. If parameter values are changed, save values into the
permanent memory using parameter 16.07 PARAM SAVE. The new settings will
take effect when the drive is powered up again, or after re-configuration is forced
using parameter 90.10 ENC PAR REFRESH.
