PLCopenPlus Function Blocks for Motion Control 2013-04-13 268
Y_ResetAbsoluteEncoder
This Function Block clears absolute encoder alarms caused by battery
power loss, cable disconnection, etc. This function block is equivalent to
the Fn008 servo amplifier function, which can be performed from the front
panel of an SGDH amplifier or via SigmaWin, or via the MPiec controllers
webserver page.
WARNING: After performing this function, the motor position will be
cleared and must be re-established (see
MC_SetPosition ) to avoid
mechanical damage to the machine.
With firmware 1.2.3 and higher, an A.CC0 alarm (multiturn disagreement
alarm) can also be cleared.
