91.26 SSI TRANSMIT CYC
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
(0) 50 us
(1) 100 us
(2) 200 us
(3) 500 us
(4) 1 ms
(5) 2 ms
91.27 SSI ZERO PHASE
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
(1) 45–135 deg
(2) 135–225 deg
(3) 225–315 deg
91.30 ENDAT MODE
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
(0) Initial pos.
(1) Continuous
(3) Cont.spd+pos.
91.31 ENDAT MAX CALC
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
(0) 10 us
