Chapter 3 I/O ports
- 36 -
CN2-26 +24V: +24V (input)
CN2-27 FWD pulse+: FWD+ (input)
CN2-28 FWD pulse-: FWD- (input)
CN2-29 REV pulse+: REV+ (input)
CN2-30 REV pulse-: REV- (input)
● Function
These ports receive position commands in the position mode.
The both [line driver] and [open collector] can be used for the commands. For the [open collector]
system, both signal voltage of [+24V] and [+5V] are acceptable. The connection to the ports is different
in the selections.
Note 1: The port [CN2-26 +24V] is not a power supply. The HA-655 driver does not have an internal
power supply for inputs.
Note 2: Three types of command configurations of [2-pulse],[1-pulse],[2 phase pulse] are available by
setting [parameter mode] → [1: command configuration]. This has no effect on the connection
specifications.
● Connection
The details of the input ports are shown in the figure below.
Specifications of the input ports
are as follows:
Specifications of the input ports
(1) Power voltage:
In case of +24V: +24V±10%
In case of +5V: +5V±10%
(2) Current I: 16mA
(less than 20mA)
◆ Connections for Line driver command
(1) Connect FWD command to [CN2-27: FWD+]
and [CN2-28: FWD−].
(2) Connect REV command to [CN2-29: REV+]
and [CN2-30: REV−].
(3) Open [CN2-26: +24V].
Note: Use line drivers of EIA-422A
standard.
