Description
Change in direction of rotation allowed below 2440 Hz.
Change in direction of rotation allowed below 1220 Hz.
Change in direction of rotation allowed at any pulse
frequency.

Selects which encoder cable channels and wires are
monitored for wiring faults.

A+, A-, B+ and B-.
A+, A-, B+, B-, Z+ and Z-.
(Visible when 92.01 Encoder 1 type
Selects the serial link mode with an EnDat or SSI encoder.
Single position transfer mode (initial position).
Continuous position data transfer mode.
(Visible when 92.01 Encoder 1 type
Selects the maximum encoder calculation time for an EnDat
encoder.
Note: This parameter needs to be set only when an EnDat
encoder is used in continuous mode, ie. without incremental
sin/cos signals (supported only as encoder 1). See also
parameter 92.30 Serial link

(Visible when 92.01 Encoder 1 type
Selects the transmission cycle for an SSI encoder.
Note: This parameter needs to be set only when an SSI
encoder is used in continuous mode, ie. without incremental
sin/cos signals (supported only as encoder 1). See also

(Visible when 92.01 Encoder 1 type
Defines the length of an SSI message. The length is defined
as the number of clock cycles. The number of cycles can be
calculated by adding 1 to the number of bits in an SSI
message frame.
