Encoder Clear Using Remote Operator (When Absolute Encoder Is Used) - Sanyo SUPER BL P5 Manual

6. OPERATION
6.4 Encoder Clear Using Remote Operator
When the power is first turned on after the amplifier and the motor are wired, the alarm "U"
(battery alarm) may come on even though a lithium battery is connected. This is because,
when an absolute encoder is used, the absolute position is not fixed inside the encoder if the
battery backup is less than 20 hours, causing an alarm to be output. The encoder can be
cleared without wiring for CN1 encoder clear signal by executing ECLR (mode 7, page 4)
using the remote operator and turning the power on again, which releases the battery alarm.

The alarm "U" will be cleared.
1 Our recommendation: Use a Toshiba lithium battery (ER6V: 3.6 V, 2,000 mAh).
The battery life is estimated at approximately 6 years.
2 On the ABS-E absolute encoder, alarm "8" (sensor error) may be issued after the power
is turned on for the first time after the amplifier or motor is wired. This is because the
voltage to be supplied to the sensor is lowered due to charging to the capacitor in the
encoder. The alarm can be reset by turning the control power on again.
In case of use without connecting retium battery in an application not using multiple
rotational data for wiring-saved absolute sensor (ABS-E.S1), set Func6, bit5 to "1" before
turning control power ON again. Thus, alarm "U" (battery alarm) shall not be detected
when turning control power ON again.
