Power ON sequence for absolute system ABS
Note 1: The figure above shows the power-ON sequence for the setting [0: ABS-REQ signal] for the
parameter of [parameter mode]
→
[ H: ABS data request timing]. For the setting [1: at control
power-ON], the signal in the block is not necessary.
Note 2: An absolute pulse train for absolute encoder is outputted after around 1 ms of outputting
phase-Z signal.
Refer to [3-6-2 Outputting position data from output port: CN2] for outputting position data.
Note 3: The servo-ON signal is unaccepted until completing the transmission of a set of pulse trains by
the [position data request] signal.
Note 4: The [alarm 57] may occur if the encoder rotates more than 127 resolvable position while the
revolution counter is transmitting a pulse train.
Note 5: After turning on the control circuit power, enter Servo ON after turning on the main power even
though the time to turn on the main power is not specified.
