CN2-4 FWD enable: FWD-EN (input)
CN2-5 REV enable: REV-EN (input)
● Function
While the [FWD enable] is [ON] the actuator rotates forward when the [CN2-31 speed command:
SPD-CMD] is [+]. In contrast, the actuator rotates in reverse for the [CN2-31] is [-].
While the [REV enable] is [ON] the actuator rotates in reverse when the [CN2-31 speed command:
SPD-CMD] is [+]. Conversely, the actuator rotates forward when the [CN2-31] is [-].
When both signals of [FWD enable] and [REV enable] are [ON] or [OFF], the actuator is holding the
position or zero speed depending on the setting of [parameter mode]→[7: zero clamp].

● Connection
Refer to [CN2-1: input signal common].
CN2-6 Command change: CMD-CHG(input)
● Function
The function can operate the actuator without a command signal at the speed specified by [tune mode]
→[6: internal speed command].
OFF: command speed
ON: internal speed
● Connection
Refer to [CN2-1: input signal common].
CN2-8 Input common: IN-COM(input)
● Function
The same functions as CN2-1

free state occurs at alarm
occurrences
during
no power
supply for the main circuit or the control circuit, or no servo-
ON
signal. If large unbalanced load is applied
to actuators, the
servo-free state may cause physical injury.
