Serial absolute synchronous encoder specifications
*1 When "o-ring" is required, please purchase separately by a customer.
*2 If it exceeds a permitted speed at power OFF, a position displacement is generated.
The serial absolute synchronous encoder backs up the absolute position with the battery for back up of
absolute position data of the servo amplifier (MR-J4-B-RJ) it is connected to.
Specifications of serial absolute synchronous encoder input (CN2L) of servo amplifier
