4.6.2. Absolute value encoder initialization
1) When the absolute value encoder requires initialization
- During first operation
- When the encoder cable is separate from the servo drive
- After replacing the battery
- When the absolute encoder related alarm is generated
2) Absolute value encoder initialization (reset) method
- 17bit serial absolute value encoder: When it sets the origin by itself, set the parameter
(P01-20) to “ON” and it will change to “ON =>OFF” to initialize the current position. (Multi-
Turn data reset). When the absolute value related alarm is generated, execute alarm reset
by using alarm reset contact point (ALMRST).
- When it sets the origin by itself, set the parameter (P01-20) to “ON” and it will change to
“ON =>OFF” to initialize the current position. Or connect the power to encoder terminal
ERST (CN2-20) and Vcc terminal (CN2-19) for more than 4 seconds.
