Parameters and firmware blocks
264
91.26 SSI TRANSMIT CYC FW block: ABSOL ENC CONF (see above)
Selects the transmission cycle for SSI encoder.
Note: This parameter needs to be set only when an SSI encoder is used in continuous mode, ie, SSI
encoder without incremental sin/cos signals (supported only as encoder 1). SSI encoder is selected
by setting parameter 91.02 ABS ENC INTERF to (4) SSI.
(0) 50 us 50 µs.
(1) 100 us 100 µs.
(2) 200 us 200 µs.
(3) 500 us 500 µs.
(4) 1 ms 1 ms.
(5) 2 ms 2 ms.
91.27 SSI ZERO PHASE FW block: ABSOL ENC CONF (see above)
Defines the phase angle within one sine/cosine signal period that corresponds to the value of zero on
the SSI serial link data. The parameter is used to adjust the synchronization of the SSI position data
and the position based on sine/cosine incremental signals. Incorrect synchronization may cause an
error of ±1 incremental period.
Note: This parameter needs to be set only when an SSI encoder with sine/cosine incremental signals
is used in initial position mode.
(0) 315–45 deg 315–45 degrees.
(1) 45–135 deg 45–135 degrees.
(2) 135–225 deg 135–225 degrees.
(3) 225–315 deg 225–315 degrees.
91.30 ENDAT MODE FW block: ABSOL ENC CONF (see above)
Selects the EnDat encoder mode.
Note: This parameter needs to be set only when an EnDat encoder is used in continuous mode, ie,
EnDat encoder without incremental sin/cos signals (supported only as encoder 1). EnDat encoder is
selected by setting parameter 91.02 ABS ENC INTERF to (2) EnDat.
(0) Initial pos. Single position transfer mode (initial position).
(1) Continuous Continuous position data transfer mode. Measured encoder speed is
not calculated and is always 0.
(3) Cont.spd+pos. Both speed and absolute position are transferred continuously.
91.31 ENDAT MAX CALC FW block: ABSOL ENC CONF (see above)
Selects the maximum encoder calculation time for EnDat encoder.
Note: This parameter needs to be set only when an EnDat encoder is used in continuous mode, ie,
EnDat encoder without incremental sin/cos signals (supported only as encoder 1). EnDat encoder is
selected by setting parameter 91.02 ABS ENC INTERF to (2) EnDat.
(0) 10 us 10 µs.
