 Parameter
Table (1)Encoder constant-setup sets up the actual number of pulses of the encoder based on the ter-
minals to be used.
Table (2) encoder phase sequence selection is set up in accordance with the encoder’s phase
sequence.
When [CA-90] = 02, the main-body speed feedback is enabled while [CA-90] ≠ 02, PG option unit
speed feedback is enabled.
