Parameters and firmware blocks

Group 90 ENC MODULE SEL
Settings for encoder activation, emulation, TTL echo, and communication fault
detection.
The firmware supports two encoders (or resolvers), encoder 1 and 2. Multiturn
encoders are supported only as 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) and two digital inputs for position latching
• Absolute Encoder Interface FEN-11: absolute encoder input, TTL input, TTL
output (for encoder emulation and echo) and two digital inputs for position
latching
• Resolver Interface Module FEN-21: resolver input, TTL input, TTL output (for
encoder emulation echo) and two digital inputs for position latching
• HTL Encoder Interface Module FEN-31: HTL encoder input, TTL output (for
encoder emulation and echo) and two digital inputs for position latching.
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 ABSOL ENC CONF
(page 229), 92 RESOLVER CONF (page 234) and 93 PULSE ENC CONF (page
235).
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.
