High frequency
input channel
Except for S1–S4, this terminal can be
used as high frequency input channel.
Max. input frequency: 50kHz
Duty cycle: 30%–70%
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 off (STO) redundant inputs,
connected to external NC contacts. When
the contacts open, STO acts and inverter
output stops.
2. Safety input signal cable: shielded, with
length within 25m
3. H1 and H2 terminals are short connected
to +24V by default. Remove the jumper on
the terminal before using STO function.
