Chapter 2 I/O ports
HA-680_V04 - 37 -
(I/O signal functions for speed control)
CN2-12 Input signal common: IN-COM (input)
● Function
The common for input signals CN2-7, 8, 9, 10, and 11. It provides the input signal external power supply.
◆ Connection
Connect +24 V of the input signal external power supply.
CN2-13 Encoder Monitor ground: MON-GND (output)
● Function
This is the common port for the monitor ports [CN2-21~26].
◆ Connection
Make connection as the ground for encoder monitor terminals C2-21 to 26.
CN2-19 Speed command: SPD-CMD (input)
● Function
Input the speed command voltage signal which is obtained by [parameter]→[9: speed conversion factor].
This speed command voltage can be obtained using “30: Speed command input factor” in “Parameter.”
The direction of rotation is specified by the polarity (+/-) of the speed command and input signals of
[CN2-8 FWD enable: FWD-EN ] and [CN2-9 REV enable: REV-EN].
While the [FWD enable]: is ON the actuator rotates forward when the [CN2-19 Speed command:
SPD-CMD] is [+]. In contrast, the actuator rotates in reverse for the [CN2-19] is [-].
While the [REV enable]: is ON the actuator rotates in reverse the [CN2-19 Speed command: SPD-CMD]
is [+]. In contrast, the actuator rotates forward when the [CN2-19] is [-].
When both signals [FWD enable] and [REV enable] are ON or OFF, depending on the setting of
[parameter]→[38: zero clamp], the actuator is either holding the position (setting:1) or zero speed
(setting: 0).

Observe the allowable input voltage.
The range of the input voltage is between –10 V and +10 V.
Any voltage outside this range may damage the driver.
