1. Internal impedance: 3.3kΩ
2. 12 – 30V voltage input is available
3. The terminal is the dual-direction input
terminal
4. Max. input frequency: 1kHz
Except for S1 – S4, this terminal can be
used as high frequency input channel.
Max. input frequency: 50kHz
Duty cycle: 30% – 70%
The working power of digital input is
provided by an external power supply.
Power range: 12 V–30 V
1. Contact capacity: 50mA/30V;
2. Output frequency range: 0 – 1kHz;
3. Default is STO state output indicator.
1. Safe torque stop (STO) redundant input,
externally connected to NC contact, STO
acts when the contact is open, and the
drive stops output;
2. The safe input signal cable should be
shield cable within 25m.
3. When employing STO function, please
disassemble the short circuit plate on the
terminals shown in fig 3.10 and fig 3.11.
External 24V±10% power supply and the
maximum output current is 200mA。
Generally used as the operation power
supply of digital input and output or external
sensor power supply
