Parameters and firmware blocks
160
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 165 ), 92 RESOLVER CONF (page 170 ) and 93 PULSE ENC CONF (page
171 ).
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 .
