Description
Set the type of the SSI encoder.
• Single Turn
• Multi Turn
Set the frequency of the clock signal to perform
synchronous data communication with the SSI
encoder.
Indicates the time until the next communication is
ready to start after the output of the last clock signal.
Set the monoflop time according to the specifications of
the SSI encoder to be connected.
For details on the monoflop time, refer to the following.
Page 120 Monoflop time
Set whether to detect an error (disconnection, short-
circuit) of the data signal wire externally connected to
the SSI encoder.
• Error detection disabled: Disable
• Error detection enabled: Enable
For details on the signal error detection, refer to the
following.
Page 121 Signal error detection
The counting direction of received data from the SSI
encoder can be changed by setting this item.
• Forward
• Reverse
For details on the counting direction setting, refer to the
following.
