Section 2-2
Ports1 and 2
Two pulse inputs (high-speed counter) and two pulse outputs can be used
simultaneously via ports 1 and 2. To determine which has functional priority,
the appropriate Port Mode setting must be entered in the PC Setup
(DM 6611).
Note
1.
Mode 0: Accele Independent Mode; Mode 1: Accele Con-
tinuous Mode; Mode 2: Decele Independent Mode; Mode 3: Decel-
