PW Digital power supply
The working power of digital input is
provided by an external power supply.
Power range: 12 V
–30 V
Y1 Digital output
1. Contact capacity: 50mA/30V;
2. Output frequency range: 0
– 1kHz;
3. Default is STO state output indicator.
STO function
input
24V-H1 STO input 1
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.
