SF1 input state SF2 input state STO functional state
ON ON no-trigger

OFF ON trigger
OFF OFF trigger
Note: Conduction ON input voltage requires 24VDC, (each input signal has a minimum current
capacity of 5mA) OFF The input voltage must be 0 to 5VDC or left blank.
4 Mounting the Drive
The SSDC multi-axis series drives can be mounted through the narrow sides of the heat sink
using M3 or M4 screws. If possible, it is best to secure the drive to a smooth, flat metal surface,
which helps to dissipate heat from the drive. If this is not possible, it may be necessary to dissipate
heat through a fan to avoid overheating the drive.
• Do not install the driver in a place without ventilation or where the ambient
temperature is higher than 40
℃
.
• Do not install the driver in a humid area, or where metal debris or other conductive
objects can easily enter the driver and cause a short circuit.
• Ensure that there is sufficient airflow around the drive.
• When installing multiple SSDC drives, ensure that the space distance between the
drives is at least 2cm.
