Error and warning bits can be cleared by issuing the SCLR command or by power cycling. See Section 8.6 for details on issuing this
command. The SCLR command may also be issued manually using the Position Preset pin. See Section 6.1 for details.

7. SSI Protocol

7.1 Overview

Synchronous Serial Interface, or SSI, is a simple serial communications protocol designed for data transfer between computers or
user terminals and smart sensors.
Model A36R encoders with SSI communication are always slave devices. The fieldbus device (i.e., controller, counter) is always the
master device, supplying a clock signal to which the encoder responds synchronously.
The SSI master must be configured to the correct data length and clock rate.
The master must also be configured to display the correct data type (gray or binary) supplied by the encoder. This is determined
by the order code and cannot be changed.

Solution
Verify +VDC is within specified range.
Internal temperature sensor is not yet in steady state. If you are trying to
read temperature or manipulate temperature limits, wait until device is
ready.
Sensor junction temperature is above specified maximum threshold. See
Section 8.6 for setails on setting this threshold. Temperature high limit is
140° C by default.
Sensor junction temperature below specified minimum threshold. See
Section 8.6 for setails on setting this threshold. Temperature low limit is
-40° C by default.
Voltage at V is below the early warning threshold (see Table 1). Replace
BAT
battery soon or check that external voltage source at VBAT is set correctly.
These bits are unused.
