Pulse I/O Board 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: Acceleration + Independent Mode; Mode 1: Acceleration + Con-
tinuous Mode; Mode 2: Deceleration + Independent Mode; Mode 3: Decel-
eration + Continuous Mode.
2. The port modes for both ports 1 and 2 is always set to the same mode, i.e.,
either High-speed Counter Mode and Simple Positioning Mode. The mode
cannot be set separately for each port.
