Parameters and firmware blocks
267
Group 93 PULSE ENC CONF
TTL/HTL input and TTL output configuration. See also parameter group 90 on page
256 , and the appropriate encoder extension module manual.
Parameters 93.01 … 93.06 are used when a TTL/HTL encoder is used as encoder 1
(see parameter 90.01 ENCODER 1 SEL ).
Parameters 93.11 … 93.16 are used when a TTL/HTL encoder is used as encoder 2
(see parameter 90.02 ENCODER 2 SEL ).
Typically, only parameter 93.01 / 93.11 needs to be set for TTL/HTL encoders.
Note: Configuration data is written into the logic registers of the adapter once after
the power-up. If parameter values are changed, save values into the permanent
memory by parameter
16.07 PARAM SAVE . The new settings will take effect when
the drive is powered up again, or after re-configuration is forced by parameter 90.10
ENC PAR REFRESH .

Firmware block:
PULSE ENC CONF
(93)
This block configures the TTL/HTL
input and TTL output.
93.01 ENC1 PULSE NR FW block: PULSE ENC CONF (see above)
Defines the pulse number per revolution for encoder 1.
0…65535 Pulses per revolution for encoder 1.
93.02 ENC1 TYPE FW block: PULSE ENC CONF (see above)
Selects the type of encoder 1.
(0) Quadrature Quadrature encoder (two channels, channels A and B).
(1) single track Single track encoder (one channel, channel A).
93.03 ENC1 SP CALCMODE FW block: PULSE ENC CONF (see above)
Selects the speed calculation mode for encoder 1.
*When single track mode has been selected by parameter
93.02 ENC1 TYPE , the speed is always
positive.
