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 .
